activate post-processing for user defined field
Hello, I have created a user defined field inside cs_user_parameters.c (I underline .c), through "cs_field_create". Nevertheless, I am not able to find a way to activate its post-processing... Anybody knows what is the function I have to use for that? Thank you very much in advance. Best r...

Re: restart problems with v7
Hello Luciano, I indeed saw (before creating this new subject) your post on the forum related to your restart issues. I misunderstood the solution you found: I tried to change the read method, and not the write method... Actually I have just done a test changing both methods: the restart seems to wo...

restart problems with v7
Hello, Has anyone had problems with restarts in v7? I cannot manage to restart a simulation. The previous simulation was completed with no errors. The error looks as a memory issue, could it be due to the environement rather than directly to the code? READING THE MAIN RESTART FILE Start reading Read...

Re: ALE method and Internal Coupling Problem
Hello, As Luciano said, I think you have misunderstood the internal coupling capabilities: it allows to solve the motion of a rigid body under the fluid forces, it is not a CFD-FEM coupling tool. Therefore, no solid mesh can be included. Please provide more details about your case in order to discus...

Re: how should i choose the inlet turbulent in boundary conditions?
Hi, You can either impose directly the values of k and w at the inlet, if you know them, or estimate them based on correlations function of Dh , turbulence intensity, ... If you don't know the k and w values, you are obliged to use a correlation. Does this answer your question? What does the inlet b...

mesh viscosity in v7
Hello, The user guide of v7 says one can modify mesh viscosity for an ALE simulation inside the cs_user_physical_properties.f90 routine, as in previous versions. Nevertheless, in the online documentation the mesh viscosity is not included among the properties that can be modified inside cs_user_phys...

SCRIPTS directory in v7?
Hello,
I don't know if I made a wrong installation, but with the new version 7 of code_saturne I do not find the SCRIPTS directory when I create a case. Is that normal?
Thanks a lot for the help,
Kind regards,
Daniele

Re: issues with user routine parallelization
Hello, Thank you, yes the option of defining separate "sub-domains" on the faces in the meshing process (is this what you mean by "field"?) would allow to access directly the face portions, but becomes maybe not very practical for a large number of fields. If I write a condition ...

Re: issues with user routine parallelization
Hello, Thank for all these details. I did not know that C operators allowed to perform more operations than in Fortran... Nevertheless, I am doing all this inside the “cs_user_boundary_conditions_ale.f90”, in order to impose mesh deformation: I am not sure the analogous C routine exist? To answer yo...

Re: issues with user routine parallelization
Hello, Thanks for your help. Actually the value of the indexes is different, there are index values inside ifac_par which are not present inside ifac_test, and vice-versa. I have to do "ifac_local_r = real(ifac_local)" because the parallel function cs_parall_allgather_r requires real array...
