Dear Yvan,

Have you had time to check about the CDO settings with your colleagues?

Thank you very much.
Best regards,
Daniele

Hello, I have tried to use the CDO approch for the ALE mesh velocity, in v6.0.2. When I put cs_glob_ale = CS_ALE_CDO (instead of cs_glob_ale = CS_ALE_LEGACY) inside the cs_user_parameters.c, I get an error on the definition of the moving boundary conditions: ../../../src/base/cs_ale.c:1414: Fatal er...

Hello, For a ALE simulation, the mesh viscosity defined inside the user_physical_properties.f90 is defined only once at the beginning of a simulation. In my case, I fix the cell mesh viscosity value based on geometrical conditions based on the distance from the moving boundary. Under significant mes...

Dear Luciano,

You are right, it works correctly after doing a parcpt!
Thank you very much for your precious help.

Best regards,

Hello, When postprocessing profiles, I sometimes get the error: System error: File too large ../../../src/fvm/fvm_to_plot.c:203: Fatal error. Error opening file: "profiles/profile5_120170.dat" And the simulation crashes. It looks like a memory problem. Have you ever faced this error? Thank...

Hello, Thank you very much for your help. cs_parall_allgather_r() actually seems to be what I was looking for. Nevertheless, I am a bit confused since cs_parall_allgather_r() requires the size of the local and global array as inlet parameters... but they are not known... And therefore this syntax: c...

Hello, I am trying to store the surface normal vector components in arrays (nx, ny, nz) and the norm (nn). Through the following code inside the cs_user_extra_operations.f90 I managed to do it, for a serial (1 processor) simulation: call getfbr('WALL1', nlelt1, lstelt) do ilelt = 1, nlelt1 ifac = ls...

Hello Yvan, Thank you for your help. What I understand is that "Time averages" in the GUI calculates the average of the selected variables for all cells, is that right? Then, I can define a profile calling that average? Have I understood exactly? Is there an example in any user routine? Th...

Hello, I was wondering if it is possible to make code_Saturne calculate the time average of a user defined profile or probe. In the GUI, when I add a time average, I do not understand how to set the x,y,z position where I want the average to be calculated. Maybe I misunderstand the use of time avera...

Hello Erwan, Thank you for your help. Actually I am simulating the cold leg mixing experimental test, where density difference depends on the species (scalar) mass fraction. Density difference is around 200 kg/m3, with the average density (between the two species) equal to around 1000 kg/m3. If I re...
