- It"s a very informative and good course to get into OpenFOAM.» (Good)
- The level of experiences in OpenFoam among the students differed significantly. This makes it not really a peer-review process. It might further be differences in workload depending on the level of initial knowledge.» (Good)
- There is in general a good structure in the course. Perhaps it would be beneficial to try to get a bit deeper in to the code, getting past the application layer.» (Good)
- Very good course, but I think it requires some modifications to allow for different backgrounds and other differences between the students.» (Good)
- Very good course and excellent subject.» (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?

- I think I spent approximately what was required (20 hours per week). Perhaps a little bit more. If there was something I would have been without it was Jelena"s part. There was to much code which she went through and when it is not anything you are directly working with you loose focus. Otherwise I think all lectures were very informal.»
- Less homework»
- around 100hr in total»
- As I expected before taking this course I spent more time on this course than on a general master course.»
- I spent more or less exactly 220 hours on the course, including the lecture. This is somewhat more than the required workload for 7.5 credits. However, this is related to my lower level of knowledge from the beginning. It is probably the right amount of workload and I don"t see where you could remove material.»
- Around 300 hours.»
- 400 h»
- Difficult to say, approximately the time equivalent to 7.5 credits. The work load is fair I would say.»
- I think, about 20 hours per week, in addition to the lectures, before un-registering.»

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 worked fine for me with lectures and afterwards assignment/project work.»
- Can be made more compact instead of 3 weeks»
- The current time plan is ok. But could it also be possible that all the lectures is put together, e.g. we have a full week of lectures first, and then we do all the assignments later. In this way, the long distance student can just come once to Chalmers. »
- Good solution»
- It is a good schedule. Even better for long distance PhD students would be a whole week schedule.»
- It was good, 6 complete days for course in three weeks is reasonable for PhD course»
- The fact that it was full days was ok. The distribution of two full class days/week followed by an assignment is a very good way of keeping the students focused and working on the project. »
- Very good. Good to have chunks of days. »
- I think it"s a good idea, but since the course is offers in quarter 1, it would also be a good idea to send an email to those registered containing the first lecture note, or better yet, a dedicated document on how to get started before the course actually begins. This would allow for someone enthusiastic, like me, who won"t have enough time to keep up with the course during the semester to get a head start.»

- More examples» (Some extent)
- The main problem here is that the teacher couldn"t not cover the basics in an appropriate level, in my opinion. Information about OpenFOAM is very scarce and not so good. I wasn"t (and still am not) comfortable with C++. The mixture C++ and OpenFOAM styled C++ was extremely difficult to grasp (again, practically nothing can be found online). This caused me to have a very low productivity during the course after the third/fourth day. I think that there should be some more time spent dealing with the C++ related issues. The examples given for C++ code example to learn during class are very, very, very far from what is expected for someone to understand the construction of boundary conditions and other examples. I think this should be tuned. I know the course is not about c++, is about OpenFOAM, but it is crucial to get it to properly use OpenFOAM» (Some extent)
- Knew much of it earlier...» (Some extent)
- I remember the slides being very good and easy to follow.» (Large extent)
- It was sometimes hard to follow through all the steps on the screen. But one could re-do everything with the course script.» (Large extent)
- Mentioned important parts so students get key points for this software the workshop part is missing. Teacher must become sure that all the students can run some tasks in the class. Nowadays it is more lecturing compare to workshop. So my suggestion is instead of going very deep into the code in the class, try to make some tutorial and description of some codes and let students go by themselves and you just try to help them more by sitting beside them and just highlight the main parts. So in this case the student become more active and struggling more to get the result» (Large extent)
- Again, for someone who started knowing nothing about OpenFOAM and little about Linux, a preparatory study guide would have been helpful since I would often get lost in the middle of the lecture. What would be even better, in my opinion, is a short video allowing you to get started.» (Great extent)

- It could have been separated in tutorials with only commands (possibly one column) and explanations in a separated way. » (Large extent)
- for C++ part in tutorial, it is better to add some hints for extra details, examples and etc to corresponding parts in the famous book » (Large extent)

- Maybe less importance on the basic tutorials in the first assignment and one more advanced tutorial. As the basic can easily be followed in the user guide. Also you spend quite a lot of time on preparing the slides for these basic tutorials. So perhaps just present the additional utility or function object in slides and not all the basic cavity- damBreak and pitzDaily tutorials.» (Large extent)
- I wasn"t able to hand them in in time since I was lagging behind, but I think they were great.» (Large extent)
- related to course content» (Great extent)
- The assignments forced me to keep working with and applying the contents of the course lectures (ideal exercise) and demanded me to search for extra information, helping me get to know more about OpenFOAM.» (Great extent)
- The assignments are the core of the course.» (Great extent)

- A little bit more response to the optional project during the working period would have been good.» (Large extent)
- I think for people who already have a project they are working with, it"s great. But for MSc students without a project o their hands, more help in choosing one would be useful.» (Large extent)
- It was rather hard for me to decide on the project, because I had no idea about the amount of work.» (Great extent)
- Sufficient time and help from teacher» (Great extent)
- This is a keeper. It must be kept.» (Great extent)
- This is very important for the course.» (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.

- Yes the slides/lectures and assignments and project work worked fine for me. »
- The assignments are very helpful for us to get familiar with the basic usage of OpenFOAM. The project allows us to do more advanced technique related to our own research interests. Moreover, the peer-view process is very good since not only our own work can be improved due to comments, but also we read carefully on other"s topic so that we learn more applications in OpenFOAM. Hence, i would say that the learning procedure of this course is quite appropriate.»
- I think the assignments and the project are very helpful. However, the peer-review process is in my opinion only helpful to a smaller extent since the level between the students and thus the level of the projects were rather different.»
- Really steep learning curve. I"m not comfortable/happy with my knowledge of OpenFOAM source code and other features. On the other hand, the knowledge of what I can do with OpenFOAM and using it. The assignments and project are perfect. The peer-review project is flawed. I received absolutely no reply to my proposed changes, on the report I reviewed. The work load required to review a project deserved, at least, an answer and if I can"t get my evaluation with filling a review, the person replying to me should say at least something. This should be considered in evaluation. The way the report review process is distributed is excellent (nobody gets to pick what to review). »
- Yes, it feels like there is no further need as comes to assessment.»

10. What should definitely be preserved to next year?

- Worked very well how you could follow the slides during the lectures. »
- All the present content»
- peer-review»
- The assignments and the projects.»
- »
- All of what I said I like in the previews forms. »
- Final project, including review.»

11. What should definitely be changed to next year?

- The review took quite longer than I had expected. Also due to many language and phrasing errors in the report. Which I think should have been better before handing in to review. Perhaps it could be emphasized what should be included in the review. Only look at code or should the report also be evaluated. We could also have one week after the presentations to refine our own reports and slides and then hand them in to the reviewer. Just to put less work on the reviewer. Also handing in both slides and report was a little bit confusing. As this is done at the same time. Maybe the presentation could be based more on the report and the codes in the report so there would only be one thing to hand in. Also as the presentation is anyway more like a walk through the code and the report. This would save us (students) some time of preparing two things with almost same content.»
- None but add more examples»
- not yet»
- Possibly more hands on project work, like working in class on the projects after the students have started with the projects. In this way the teacher could be involved a little more in the projects and give possibly useful advise?!»
- If it is possible reduce the course content. Focus more on improving student activity. Last 2 sessions must be modified, it is very deep and boring. It is better to have some small projects during class to help students to increase programming ability which started from last week. If they understand basics they can understand by reading any tutorial later »
- On one hand, the respect for other students work on reviewing reports. On the other hand, I got a very strong feeling that the course was used by some of the students to show off their excellent knowledge of C++ to the "Professor" and dominate the class. That, had a completely disgusting effect on me. If a student is that comfortable with OpenFOAM and C++ than he/she has nothing to do in this course, except for the plain credits. Separate classes, according to students background, should be made. The constant criticising of less knowledgeable students by the supposed better ones was completely unnecessary and contra-productive. Specially in the presentations, where it the lecture should be the one to criticise and all the rest present their questions, not their approval. »
- Perhaps a bit too much time was spent on the LPT parts. Unfortunantely this lecture does not reveal alot extra on OpenFOAM. Personally I think it would be of interest to get deeper in to the programming and try give some details on the more advanced stuff needed to make your own runtime selectable models etc.»
- I can"t think of anything that should be removed, but I"ve already mentioned additional improvements in my previous comments.»

- Simple and clear homepage which works very well. Good and quick response from Håkan.» (Very well)
- Any material to help people new to OpenFOAM cope the first two weeks would greatly improve the course.» (Very well)

13. Additional comments

- It was great course and unique. But for pedagogical point of view the course must be more workshop rather than lecture»
- It thins it is of very bad idea to get in the course homepage the "assignemnts selected by quality" and "other assignment", rating them as first and second grade quality, specially when the "selected by quality" assignments were performed by students with a head start compared to the other. All this aspects of having some "trying to show off" to the other didn"t affect my performance at all, but I"m a PhD student in a course to learn, not a 16 year old football player trying to own the play ground. Besides, it is diminishing to the students that got their first contact with OpenFOAM in the course.»
- A bit of a rare course, as compared to other at Chalmers. I really think there is a need for applied courses like this one. The advantage of teaching details within a software should not be underestimated.»
- I really liked the course and was very disappointed that I was not able to finish it!»
