- The first lectures were too basic. » (Adequate)
- The course and webpage has been great reference for beginners in OF. » (Good)
- Very stressful.» (Good)
- I thought that it was a nice course for learning tips and tricks for OpenFOAM. The course it self is not so much about CFD in general and more about using OpenFOAM. I think that maybe this should be stated more clearly in the advertisement of the course. » (Good)
- Covers a lot of variety of topics in openfoam. Will be useful in the future.» (Good)
- Well thought out course with very good content.» (Excellent)
- Very good approach for spreading the use of OpenFOAM. The teaching and tutoring approach of the teacher is brilliant.» (Excellent)
- A very well structured course with an appropriate tempo, really good pedagogy, resourceful course material that make this course can offer knowledge to students with a wide range of different research projects» (Excellent)
- Even though at the beginning everything seemed to be confusing, it all became clearer while working on our own project. Really nice course in order to get an idea on how to work in OpenFOAM» (Excellent)

3. How much time did you spend on this course, and did it correspond to 7.5 "Higher education credits"?

We mean total time, that is, it comprises the time you spent in class and the time you spent on your own work. What should be added/removed?

- The time spent was much larger than other 7.5 credit courses but that is more due to the problems of the (choosen) individual tasks and previous programming knowledge. »
- I had to spent lot of time on the course especially for the project. I think it should be more than 7.5 credits. »
- I"ve spent more time, as it ties into my PhD well.»
- 280-300. It was mainly attributed to the project not developing as smoothly as planned.»
- I spent nearly 175 to 180 hours which includes attending the lecture and executing the project in the course. Yes, this course definitely corresponds to 7.5 ""Higher Education Credits"" »
- Approximately 200 h including lectures and presentation time.»
- 170 - 200 hrs. »
- The work load reflects the amount of credits earned»
- A lot of time, nearly half of the study time last semester.»
- I spent about 2 weeks on the project work and maybe 3 hours each on assignment 1 and 2.»
- 120 hours»
- 52 for lectures + presentation day For project = 110 hours (Before presentation) 18 hours for fixing and checking final report (Too slow) About 20 hours for assignments 8 hours for peer review Total 208 hours (Could be slightly under 200 though) »
- At least 100 hours»
- The course corresponded to at least 7.5 credits»
- I would say that it required much more than a usual Chalmers 7.5 ECTS course»
- Nothing to be removed as such. The project work took approximately the same time as mentioned in the course page. »
- 200 hours. »

4. Comment the schedule of the course.

The idea was to cover as much as possible in the beginning of the course in order to have as much free project work time as possible at the end of the course (it is after all a project course). One reason for having full days is to allow long distance PhD students.

- The schedule was reasonable. Unfortunately missing one lecture means missing a very large portion of all lectures.»
- I felt the schedule of the class okay. It is nice to finish all the assignments as soon as possible to have more time on project.»
- The teaching days are a bit ram-packed, but as you said, it makes it a lot easier for us who have to travel. Also, coming out 3x in a row is quite expensive, so could put students off. Maybe a more intense week or week and a half would be better?»
- The setup was very good. I wish there were more courses with similar scheduling.»
- The schedule of the course is very well planned and organized. Credits to Professor Håkan Nilsson for not only making the lectures useful and interesting but also to dedicate sufficient time to assist students at the later stage of the project. »
- The planning and schedual was very good. »
- Good and well structured.»
- Although this schedule is adopted to better suit the PhD students, considering to split the whole long day in two may improve considerably the attention and the assimilation of the lectures" content.»
- The schedule was tight. »
- The long hours of this course was rather exhausting from time to time. However, I understand the reasoning behind the scheduling and I do not think that you should change it.»
- The schedule of the course was intensive. This is definitely due to the fact that you have to accommodate long distance PhD students. So if it cannot be helped then it is the way it is. »
- It was good. The lectures were more like workshops, which I liked.»
- To have full day"s schedule is actually good for intensive learning with good understanding, while offering as possible schedules for as everybody»
- Having full days with intense teaching is a very nice concept. »
- I completely agree with the proposed schedule»
- Schedule of the course was good. Especially 2 weeks gap between lectures helps us go through the material in greater detail.»
- More breaks during the course would be nice. I think the course could have been reduced by a month. A lot of students started their work late.»

- I did learn quite a lot of stuff in this course. However, most of the stuff is what I would call "Tips and Tricks". I did not really learn anything major. But I understand that the course has to cater to people who have never used OpenFOAM before. » (Some extent)
- Hakan is very helpful, and willing to share his knowledge.» (Large extent)
- I had some prior experience in using OpenFOAM and ParaView, so the first occasion was a bit redundant for me.» (Large extent)
- The contents of the lecture were well presented, making it easy for the reader to execute the same commands for learning without difficulty. And the important steps for someone new to openfoam were discussed (starting from accessing computers till implementing models and debugging). » (Large extent)
- Overall the lecture were well planned and rather easy to follow. The main drawback is if you for some reason fall behind during the extensive copy pasting it is very tough to catch up and at the same time follow the lecture.» (Large extent)
- Everything pretty much was really nice to follow during clases. The only part that I think might be improved is the part regarding C++. Even though it was not the main objective of the course I think it was way to much to cover in only one day for those who had no C++ experience. Maybe an extra day could be added on that part» (Large extent)
- The teaching was really good but in my case If I am unable to have breaks at regular interval atleast 70 mins once, it is really hard to grasp all the information presented at the lecture.» (Great extent)

- I did consult the course material from time to time to remember certain commands.» (Some extent)
- it"s good for reference.» (Large extent)
- Without the course material I could not finish the two assignments at least. » (Large extent)
- I always check the commands in the lecture notes during my project which is in OpenFoam.» (Large extent)
- The course material gives basic knowledge plus viable online resources.» (Great extent)
- The slides are really clear and very useful» (Great extent)
- Course material is very well designed and I referred to it during the project work throughout» (Great extent)

- I did not think that Assignment 1 and 2 were very helpful. They were mostly tedious. A lot of small assignments containing quite easy stuff. I would have preferred two single assignments with some more contents. E.G "Implement this and simulate that". However not as time consuming as the project. Something that could be done in a 5-6 hour session» (Small extent)
- I didn"t like the high pass mark, as the questions were sometimes subjective.» (Some extent)
- Maybe the assignments were a bit too theoretical.Maybe running small test cases with a very small report could be a better choice as we have 2 weeks to submit the assignments» (Some extent)
- I would say that instead of having such theoretical questions in the assignments, it might better to hand out a case and ask direct questions on that case. For example hand in a case which is completely prepared and ready to run and ask question such as, what is the boundary condition applied in the inlet patch? so the student has to search through a real project in order to find the answers» (Large extent)
- Made me think a little. » (Large extent)
- The C++ part really helps me to improve my ability in reading codes. » (Great extent)
- Generally good, personally I think there are a little bit too many straight forward questions that can be found directly from course slides. Some questions that requires self learning are relatively moe intersting, and they can be also less challenging if guides are provided well. Also as I"ve been experienced that some questions can be easily misunderstood, which makes me a bit nervous combined with pass/fail grades. But again, some pressure is always good as motivation.» (Great extent)

- I should have selected a different project. » (Some extent)
- I have a hard time seeing a better way of getting used to the software and the capabilities.» (Great extent)
- It forced myself to acquire knowledge in a so far untouched field, which I will now use for my PhD work.» (Great extent)
- The project was the main part of the course and where I learned most.» (Great extent)
- It is a project that pushes me reading a lot on the source code. The report revision helps me understand a lot with the ideas behind the software.» (Great extent)
- A case/project study is always the best way to learn as practice.» (Great extent)
- Having to prepare and modify actual OpenFoam projects made you realize of a lot of details that can not be covered in the lectures» (Great extent)
- Project was essential in understanding the nuances of the code. We had to search for a lot of resources online which additionally helped build our knowledge not only in the software but also in the domain we were working in.» (Great extent)

9. Comment the assessment of your learning.

Is the assessment of your learning (the assignments, the project, and the peer-review) appropriate? Give some suggestions.

- I felt the peer-review really useful in writing the final project report.»
- The idea of assessing the course based on project work is very good. The idea of peer-review among students is also very good. Regarding the assignments: I personally do not think that asking for written answers in the exam is worth the correcting effort. The necessary work for correction simply does not match the learning outcome.»
- Yes, the assessment was appropriate.»
- The lectures were good but sometimes not easy to do all the steps your self during sessions. The first two sessions could include more information and examples at a higher level. Now the first session was very basic and known to most of the course participants. »
- The assignments helped recapping the lectures. The project helped into understanding the classes, structure and skeleton of the OF software.»
- Yes, it is. The peer-review process is so much helpful. »
- I would have liked it if the workshops were a bit more interactive and if they encouraged us to think a little bit more. Now it was just copy past into the terminal, and it got quite mechanical after a couple of hours.»
- The assessment was fair enough.»
- Yes it was appropriate. »
- I can only say something about assignment and I think I"ve talked a bit of it previously. Maybe the assignments can be more various instead of just write answers for questions but it can also be impractical for you to get the score.»
- Yes.»
- My peer reviewer did not give »

10. What should definitely be preserved to next year?

- All of them»
- Scheduling, the idea of doing project work instead of an exam. The guest lecture by Hrv. The teacher"s approach on tutoring and supporting the students.»
- The topics that I would suggest to preserve are 1. High-level programming in OpenFOAM. 2. Basic of C++, and how it is used in OpenFOAM. 3. Some utilities and functionObjects in OpenFOAM. 4. Implementing functionObjects, boundary conditions and turbulence model. 5. »
- The project work and the presentations. The two assignments in the beginning is a good way to see that you follow the basics.»
- Guest lectures.»
- I think that the lectures are very good and I learned a lot of stuff. Maybe you should go a little deeper into the code towards the end. For instance I would very much like to have learned more about templating and it"s use in OpenFOAM. As this is something that is used quite extensively, and that code can be quite hard to read (E.G the Thermophysical and Lagrangian libraries). »
- The contents of the lecture, project work.»
- The structure of the course. »
- Not sure what is needed to be changed...»
- The full day lectures with intense teaching.»
- The course seems fine the way it is»
- The structure of the course was good. »

11. What should definitely be changed to next year?

- number of credits»
- The report and the tutorial files are in my opinion somewhat redundant. The report merely tells the reader how to create the tutorial files. I would prefer a more abstract approach in general providing the student the opportunity to explain more why he chose to address the problem in the way he did and also provide hints to the reader on how to solve related problems. In a nutshell: The report should cover the material more in general. However, if the teacher sticks to his approach, he should tell the students beforehand that he envisions the report to be like a step by step manual. In general: I would shift the focus from implementing/programming more code to actually describing/explaining/using the tools in OpenFOAM that are already there.»
- Peer-review process did not give much learning about the software. »
- An option can be kept where in peer-review can made with PDF reviewer. This is easy for the reviewer to point out spelling and grammatical mistakes, which is other cumbersome to mention in another review report. Report can made to just general comments, if required. Also, can save some time. Also, it will be good idea to mention number of versions and branches of OF available and reason for the same. »
- Nothing»
- Assignments 1 and 2.»
- Although the assignments were useful, they had a lot of questions and were intensive. The assignments could be simplified by reducing the number of questions.»
- Maybe slightly longer breaks during lectures. It"s okay to have 0800-1600 instead of till 1500. »
- Maybe we can use the forum more. A forum discussion is always a very huge source of learning.»
- The main thing that I was disappointed about is the lack of requirements on the documentation for the different part of the project. There are no written requirements of the report on what should be included and what is important, instead there are comments like "this is an example of a good report" and "this is an example of...". For example, it became obvious that the teacher had a requirement that it should be possible to directly copy and paste everything from the report to the terminal window, this is not written anywhere! I wouldn"t have use the tutorial like that if I found it online, that is really specific to the teacher. If that kind of requirements are important it really needs to be clarified on forehand, not through emails saying, student xxx report was good because you could copy paste directly from the pdf to the terminal...»
- Don"t think anything needs to be changed in particular.»
- Maybe the length of the course.»

- No problems here.» (Rather well)
- It was no problem to reach the teacher. He always had an open door for any problem.» (Very well)
- All course material was available in time before or just after the lectures. Easy to find and use.» (Very well)
- Excellent work in the use of ping pong» (Very well)

13. Additional comments

- One or two mandatory intermediate individual meetings between the teacher and the participant could be good to see the progress and discuss the problems. The course should be added to the selection of courses for Applied Mechanics so that more students get to take and know about the course. An additional programming course before the OpenFOAM course as a suggestion or pre-requisite would have been very useful.»
- I really enjoyed the course and learned a lot. Thank you :)»
- I am very happy that I took the course. I learned a lot, broadened my horizont and got in touch with amazing people. I hope that some of the connections will prevail in the future. Hakan did a very great job as a teacher. Additionally and besides the course, the OpenFOAM expertise cluster that he created and which the course is part of is really impressive.»
- Overall the course provided me a good introduction to OpenFoam. I always refer to some of the commands/methods from lecture notes when I work on my project. But if there was a main suggestion that I could give, i would suggest for the course to be simplified in terms of the lecture hours and assignments. The workload could be reduced. I also appreciate the effort taken to arrange guest lectures. They were very useful and added to the motivation.»
- A highly resourceful course with very precise pedagogy!»
