Re: model validation

Hi,

Please find attached the setup and mesh files. I am not really familiar with these tools but I will try them and get back to you.

Thank you for your help.

Re: model validation

Hi, Thank you for your reply. By corrupted I mean I get different errors each time, sometimes related to cells connectivity and sometimes divergence. As for the Gauss scheme it is related to the gradient terms dicretization. After changing the cell size near the wall I am interested in, the calculat...

model validation

Hi team, I am trying to validate a numerical model by running a study previously done on openfoam and compared to experimental results. The first issue I encounter is maintaining the maximum value of y+ around 4. If I understand correctly to achieve this value the first zone of the boundary layer in...

Re: user-defined functions

Hello Yvan, Thank you for your reply. When I run the calculation this time I do get the drag and lift forces after implementing a user-defined function in SRC. However, I still get the following error: /softs/Saturne/source/code_saturne-8.0.2/src/base/cs_runaway_check.c:244: Fatal error Runaway comp...

Re: user-defined functions

Hi Yvan,

Thank you for your reply, I am not sure how to generate the boundary forces using the gui do I select the user-function ?(see screenshot attached).

Kindly.

user-defined functions

Hello everyone, I am trying a turbulent wind simulation around a solid, with a Re=2.6e7, as I run the calculation with a rans model (K-w) with no wall functions I get some warnings/errors (see run_solver.log) that I don't understand. Also I have a question about the general use of user-defined funct...

Re: meshing criteria

Thank you for your reply, Indeed I am trying to achieve something similar to image10 (see attachement), and so far I can get the mesh you can see on image20 using netgen2d-1d, are there any tutorials or posts that treat similar problems? Also, what is exactly the difference between meshing my 2D geo...
