| Oct 29 at 1:58 | comment | added | Roh | @user21 Well, as an engineer, we always trying to find a wrapped bite :) . How could you send the files? E-Mail? what have you tried to simulate using your codes? Have you done any verification or validation? | |
| Oct 28 at 5:14 | comment | added | user21 | @Roh, I worked on turbulence models a while back, but did not finish since I needed to do other (FEM/PDE) things. If I recall correctly, I had a Spalart-Allmaras working but not a k-epsilon model. It should be possible to do some things in this area. I could send you the code but it will be a HUGE mess. | |
| Oct 28 at 0:52 | comment | added | Roh | @user21 What happened in V14.1 for turbulence modeling(RANS)? currently, Is it enough powerful to model an airfoil using RANS equations and Spalart-Allmaras or Wray-Agarwal turbulence model? | |
| Sep 12 at 8:52 | comment | added | Dunlop | I can only add to my previous compliments. The documentation is getting better and better, and the added functionalities in Solid Mechanics are really useful for my research and also for teaching. | |

| Dec 8, 2021 at 9:26 | comment | added | user21 | @Dunlop, I am not quite sure I entirely understand your question. I have created a chat room for us. Please join me there. | |
| Dec 8, 2021 at 9:00 | comment | added | Dunlop | In fact there is one question is, how to derive the operator form of the stress operator from the equilibrium equations? I can see that in the end they are equivalent, but if one wanted to prepare the equations from scratch how does one do it? I can tell students that the operator form is "another way" of writing the equilbrium equations, but cannot explain to them why and how it is derived. (can add this as a separate "answer" in the following if that helps) | |
| Dec 8, 2021 at 8:50 | comment | added | user21 | @Dunlop, thank you for the kind words. I glad you find this useful. If you find mistakes or have suggestions or wishes, please do not hesitate to contact me. Any specific field you are interested in? | |
| Dec 8, 2021 at 8:44 | comment | added | Dunlop | Just read the new documentation for 13 - this is excellent and will be fantastic to bring into some of the teaching I do. | |

| Jul 31, 2019 at 5:11 | comment | added | user21 | @ABCDEMMM, you can add this as an answer, but it's not going to happen for 12.1 and I would not hold my breath for 12.X either. | |
| Jul 30, 2019 at 17:50 | comment | added | ABCDEMMM | @user21 how about inelastic behaviour, creep, viscoelasticity, viscoelasto-plasticity in MMA 12.1.0? | |
| Jul 22, 2019 at 5:09 | comment | added | user21 |
@ABCDEMMM, you could edit the answer Support for PDE Whose Spatial Derivative Order Exceeds 2 and add this as an example.

|
| Jul 20, 2019 at 23:06 | comment | added | ABCDEMMM | @user21, in future can we use isogeometric analysis method in Mathematica (build-in) for high order problems, e.g. cahn-hilliard? | |
| Jun 24, 2019 at 4:08 | comment | added | user21 | @Öskå, your comment does not really relate to my question. For the highlights of the language have a look at the new in 11 and the new in 12. I can not speak for Ansys as eons have past since I last used it. | |
| Jun 23, 2019 at 18:04 | comment | added | Öskå | I use Ansys Mechanical APDL heavily every single day at work but unfortunately I haven't updated my mma since V10. How exactly would you compete with a software like Ansys? | |
| Jun 13, 2019 at 11:10 | comment | added | user21 | @b3m2a1, you comment make is sound like the FEM package internals are not documented; however, they are fully documented here and specific function have there ref pages. Also, Henrik has made use of the low level FEM functions, e.g. here. So, generally, I'd say low level package things are documented. If you think something is missing, let me know. | |
| Jun 11, 2019 at 7:27 | comment | added | b3m2a1 | Something I always want is direct access to the internals of a package. Sometimes it simply doesn’t make sense for you or WRI to try to implement everything. Instead I think it’d be really cool if all the work you’ve done here could be easily reused by someone like Henrik to implement their own types of solvers that simply aren’t general enough to qualify for being included in the primary FEM package. | |
