Hello Yvan, Could you try also using a "cell data to point data" filter ? Yes, it slightly improves, but for pure Hex structured mesh, i didn't expected to need this. And still with this filter, results does not look as physical as it should be (see attach picture comp.png with comparison ...

Yvan, Pressure field looks good, Yplus shows the same checkerboarding effect than wall shear. I made an additionnal test by switching from SIMPLEC to SIMPLE algorithm for p-v coupling. The results are showing the same aspect for wall shear stress. No improvement so far. If you have possibilities for...

Hello, Which field are you visualizing ? I am visualizing the field Shear_Stress defined in the output for boundaries of type wall a bug in the z-component of the boundary stresses I was thinking of that, but the x and y component are also checkerboarding... but 4.2.2 and 4.2.3 contain the fix So fa...

Hello, I am using CS 4.2.1 for a computation at Re 1e7. My mesh is block structured, very good quality (it's not mine, so it is not self satisfaction :P ). Y+ average is 0.75 so i use k-w without wall functions. Flow is incompressible, no thermic, with objective to compute drag on body. I can observ...

Hello, I may have miss it in the documentation but i am wondering if it is possible to make a run only to compute some additionnal information using cs_user_postprocess_var.f90. In my mind, there will be no need to make additional iteration, just reading the restart files and compute the new fields ...

Hello, Not sure but this may help : ModuleCmd_Purge.c(114):ERROR:107: 'MODULEPATH' not set it seems that your compilation is made with support of Module package. so make sure that you have sourced the module env before running cs. (something like source /applis/Module/3.2.10/init/bash ) Of course it...

Hello, Thank you very much for your detailed explanations. I have clearer ideas now on the use of correction with turbomachinery. For the RSM models remark is still quite confusing for me so I have to dig into it to get clear. My RSM experience (with SSG model) is until now quite disappointing since...

Thank you for considering my interrogations.

I just can make the precision that I am using the turbomachinery im my whole domain such that all the fluid is in rotation.

Regards.

Hello, I am using turbomachinery with CS_TURBOMACHINERY_FROZEN model and with the spalart shur correction activated. I looked at the formulation of this correction from the thesis of M. De Laage De Meux and also by looking at the source code. And it bring me out some questions. If I understand ( whi...
