Hi everyone, I encountered a similar issue, using version 6.0.8, on this very case of periodic turbulent channel flow, however in RANS mode. In cs_user_source_terms.f90, I implemented the source (pressure gradient) supposed to balance the viscous stresses. At the same time, I initialized the velocit...

Thanks, but cs_time_moment_reset() requires the ID of the time moment that has to be reset. If I call it from a Fortran routine, I don't even know the syntax to call the moment number. Furthermore, I want to start all my moments at the same time. Is there no way that I pass a Fortran "user-defi...

Hi, I'm using v6.0.6 and I used the examples provided in cs_user_parameters-time_moments.c . It works fine but I would like to import a user-defined variable to calculate t_start, so I can make t_start a function of some constant parameters of the flow (e.g. a given number of transit times...) I def...

OK thanks Yvan. Most of the time, I don't use the GUI, because I run my computations on remote machines. So, if I understand what you said, I should create/initialize C fields as it is done in cs_user_parameters-base.c. But, in this case, what is the point of creating user arrays in cs_user_modules....

Actually, as a first step, I was expecting some general advice. But sure, here are my routines : - cs_user_modules.f90 where I declare my arrays called 'psiomg' and 'rk'. - cs_user_postprocess.f90 where the postprocess of these arrays is (supposed to be) done. I guess that I should call the function...

Hi, I'm using v6.0.6 and I defined user arrays that I'd like to postprocess. 1) I used cs_user_modules.f90 to create and allocate them. I followed the given example for the C linking. 2) I copied the example given in cs_user_postprocess.c . But it turns out that the postprocessing of my arrays has n...

Thanks a lot, Yvan. I'm looking forward for the detailed answer.

Best regards,

Hi, I see that even when IDDES = 1 (with ITURB=60), ISCHTP is forced to 1. I'm very surprised, because DDES is a hybrid RANS/LES method, and therefore should work with the same time scheme as LES. How could I fix things properly, so that I can use ISCHTP = 2 with IDDES = 1 ? Lots of thanks in advanc...

OK thank you Yvan for your answer.

When is v7 gonna be released ?

Best regards,
Christophe

Hello Yvan,

I'm using version 6.0.6
