parallelization issues in the cs_user_extra_operations.c
Dear Code_Saturne users, I am struggling with the parallelization in the cs_user_extra_operations.c. I am using Version 7 and set up the case by SRC. Firstly, I calculate the shortest distance by using cs_geom_closest_point of each grid cell (domain->mesh_quantities->cell_cen) to the wall surface (d...

cannot access the added members to cs_fluid_properties_t
Dear Forum users, I have added an additional member to cs_fluid_properties_t, tauhrp( heat release parameter) in the cs_physical_constants.h and finished the mian fluid properties structure and associated pointer and give the value of tauhrp=4.5 in the cs_physical_constants.c at the cs_get_glob_flui...

Re: errors when use cs_user_initialization.f90
Hey Li,
Thanks for your informative reply. Now I can understand. My problems are solved by implementing the BML expression.
I have attached the code as well for others who have the same confusion.
Best regards,
Liyuan

Re: errors when use cs_user_initialization.f90
Dear Li, I have used the incompressible with variable density as you suggested. I have figured out the variable density issue by using the cs_user_initialization.c and cs_user_physical_properties.c Now the density output is as expected. However, I feel confused about how the algorithm works by using...

Re: errors when use cs_user_initialization.f90
Thanks Li for your reply.
I am setting up a case with low Ma number. I was trying to set up a state equation by using the cs_user_physical_properties.f90 and the cs_user_initialization.f90 was required. Currently, what I need is having an viable density with temperature follow the BML expression.

Re: Variable density issue for for gas combustion with EBU model
Dear Li, Thanks for your swift reply. The density has been output in the post processing. I have implemented that code and now it has an error like below: ‘cs_velocity_pressure_param_t’ {aka ‘const struct <anonymous>’} has no member named ‘idilat’ it seems like idilat is a static variable. I have al...

errors when use cs_user_initialization.f90
Dear code_saturne developers and users I am using code_saturne V7. When I used cs_user_initialization-compressbile.f90, I had an error as shown in the figure. Same error occurs when I used cs_user_initialization-gas_ebu.f90 for the combustion case. Does anyone also have the same problems when using ...

Variable density issue for for gas combustion with EBU model
Dear Code_Saturne developers and users, There seems to be a bug in the code regarding the activation of irovar=1 option in the main part of the code when gas phase combustion, especially the EBU model. The case setup has been done in the same manner as I have done it in Version-2 of Code_Saturne. Wh...
