- Är ju lite svårt att lita på något Lars gör på föreläsningarna, men slutsatserna å kommentarerna är ju alltid topp! » (Small extent)
- Did not attend» (Small extent)
- The lectures tend to get a bit messy. It is not always very clear what the goal of the lecture is.» (Some extent)

- Unfortunately the lecture notes are not well explained, especially with respect to the assignments. The assignments are interesting and excellent for the course. But unfortunately the lecture notes do not include relevant information about the project, for example it is almost impossible to know whether the results (graphs) from the assignments are correct or not, and some of the questions in the assignments have to be guessed since the answers cannot be found on lecture notes or through searching on the internet.» (some extent)
- The lecture notes are good, however, the first chapters (considering RANS) are somewhat messy.» (large extent)
- The lecture notes are good. I sometimes felt that there could be a little bit more explanatory text in the later part of the lecture notes. The first part (that was used in the fluid mechanics course) is good in that sense.» (large extent)
- Good lecture notes!» (large extent)
- Ja det är ju där allting liksom står » (great extent)

- Both assignments are about plotting properties in Matlab. I know this already and it"s not why I chose a course in turbulence modeling. The assignments take a large amount of time without giving any further understanding of the course content.» (small extent)
- Ja 7ans uppgift blev ju en pungspark naturligtvis » (some extent)
- For me personally I don"t feel as if the assignments teach me that much. I much rather prefer coding some own code using one of the mentioned models in the course.» (some extent)

11. To what extent has the assignment 2 (LES) been of help for your learning?

- Both assignments are about plotting properties in Matlab. I know this already and it"s not why I chose a course in turbulence modeling. The assignments take a large amount of time without giving any further understanding of the course content.» (small extent)
- It is really hard to know if the Matlab results (graphs) are correct or not, since there are nothing to compare the results with. Some of the questions in the assignments cannot be found in the lecture notes, so instead the answers have to be guessed. The guessing does not help in the learning process.» (small extent)
- I thing that I would learn more if we had one bigger assignment where we preferm CFD simulations like we did in the CFD course.» (some extent)
- Both Matlab assignments are just mean to discuss the plottnings and explain the behaviour of curves from a cleared simulation data, which seems not really relevant to "modelling", dvs not really to model the turbulence but more of a backward job(explain the theory from simulations, not simulate with the help of different methods/algorithms).» (some extent)
- Man fattade inte i början vad man skulle göra! Med det här nya sättet att benämna tids medelvärdeting och filtrering, kanske borde introducerats rätt redan i trean, eller är det här nån egen variant? Fast uppgiften var en fyra veckors svordomsramsa tycker jag ändå att jag fick bättre koll på hur man analyserar data och håller koll på 3 dimensioner samtidigt. » (large extent)

- This assignment consisted of following a step-by-step manual. No thinking involved at all. What is the point of that?» (small extent)
- Probably the most meaningless lab during my years at Chalmers.» (small extent)
- Did not learn much new stuff. I have used several CFD programs before» (small extent)
- Hård slöseri med tid då det inte fanns tid att se resultatet. Kanske dom första inlämningarna borde kortats av så att les i ansys kunde får en bättre genomgång? Om man nu vill ha ansys med (typ som i compressible kursen) » (small extent)
- We was not able to do any LES at all, due to some computer error.» (small extent)
- Interesting lab, but for the next year one should make sure MPI is able for the LES simulation.» (small extent)
- Compared with other 2 assignments this is more relevant that this is a simulation of a turbulence.» (large extent)

13. How valuable was the written feedback on the Assignments reports?

- If the graphs are wrong, it is not important to have feedback only saying that they are wrong. Instead it is more important to explain what is wrong and how the correct results should look like. This should be done because it does not exist anything to compare with in the lecture notes.» (of no value)
- for me it is just "passed", 3p and almost no comments.» (of some value)

- The assignments were a bit time consuming, but nothing too much. Eventhough I felt as if the amount of topics the course covered was sufficient, maybe some topics could be studied a little more in depth.» (Low)
- I did only the assignments, so I can not answer the question perfectly. » (Adequate)
- Maybe too high? I did not aim to do exam,but spent almost 100% of my time to do assignments for the first 6 weeks of the course» (High)
- The assignment took long time and offen it was hard to understant what should be answered or not.» (High)
- Can be a little bit tough for one person, difficult to get high grades.» (High)

- The course gave different theories and methods of modelling turbulence, which is very relevant and useful, however the assignment 1 and 2 are more of an understanding and discussion of differences between different models, not really to model turbulences with different methods. In this way I and some of my classmates think this can be a little bit boring :P Otherwise everything is just useful and appropriate. » (Fair)
- It is hard to see why it is of such great importance to learn to derive all equations. It would be more interesting to focus on where the diferent models are preferalbe and so on.» (Adequate)
- Very good course with competent lecturer» (Good)
- The course would be excellent if the lectures were a bit more structured.» (Good)
- The course is great. Gives a good overview of the Turbulence Modeling. Just that it is too much of things to read and remember.» (Good)
- I feel as if I know have a basic understanding of a variety of turbulence models.» (Excellent)

21. What should definitely be preserved to next year?

- The lecture notes are great.»
- Assignment 2»
- All assignments»
- The lecture notes and the administration of the course are good. The idea with learning outcomes is also very good, then one clearly knows what one is supposed to learn.»
- That you can pass the course by passing the assignments.»
- The notes definitely.»
- The examination form.»
- Lecture notes and learning outcomes.»
- Almost everything in the lecture, introductions of different modelling methods, theories with their strong/weak points osv.»

22. What should definitely be changed to next year?

- There should be a mandatory report for assignment 3.»
- Remove the assignments or produce new ones.»
- Possibly cut down a bit of the assignments?»
- The assigmnents, I think one bigger assignment where one or more different turbulence models should be programed in Matlab. This to get a bigger understanting about what and why some of the terms need to be modelled. And how it workes.»
- The lecture notes should be improved so it is easier to understand. And especially to have more graphs and information which corresponds to the assignments. »
- I would like some more practical understanding and applications, maybe some assignment where one can implement an own model (instead of many small tasks in each assignment). There could maybe be one assignment of each type, one with many small tasks to get an understanding of the theory (then I would prefer assignment 2) and one with a single larger task to write an own program (something like in the CFD course). »
- The length of the assignments. They could be divided into more parts to be handed in and they could be less repeated.»
- I like the lectures. It gives a lot of insight. But sometimes, it goes too random that I get lost. And it was the case with other students also.»
- Make the exam mandatory. I atleast felt that I had an insufficient understanding of the material from only doing the assignments.»
- Maybe the Assignment 1 and 2 can be improved, t.ex. to code an/part of an algorithm to simulate a turbulence with Matlab/ANSYS etc. However this can be tough that it takes time and students may not make it before deadline. Hard to control.»

23. Additional comments

- Tack!»
- Also I think it should be more focus on when different models can be used. Where are different models week and strong respectively?»
