Lagrangian subroutine _where_are_you

Hello, I'm implementing some new model in CS v4.0.3 and I need to understand the subroutine _where_are_you which is founded in cs_lagr_tracking.c at line 1812. I do understand that this subroutine is used to verify if the particle stay in the cell or move to the next cell though a face. But what I d...

Re: Warning: pointer cast involving 64-bit pointed-to type

Dear Yvan,

I send you my compile.log of one of my test case. To have this warning, I just copy the file cs_lagr_tracking.c and cs_lagr_tracking.h to my /SRC (without modification).

Regard,

Warning: pointer cast involving 64-bit pointed-to type

Hello, I'm using CS v 4.0.3 on linux x64 bit. When I copy any source term written in c (*.c) in my SRC, and I start my calculation, I got warning in compile.log: ... warning #2312: pointer cast involving 64-bit pointed-to type ... Do you have any idea to fix this warning? (the calculation run fine b...

Re: Post processing of particle relaxation time

Hello, I founded the answers myself: I used uslag1.f90 to add statistical variable in post processing, then call the subroutine "uslatp" in subroutine "uslast" in cs_user_particle_tracking.f90 to calculate the cumulation of my statiscal variable . Finally, I used uslaen.f90 to ca...

Post processing of particle relaxation time

Hello, I'm using CSv4.0. I used subroutine "uslatp" to modify the drag coefficient and then the particle relaxation time "taup". I would like to visualize "taup" in post-processing on Eulerian mesh as a volume statistical variables. Is it possible? For me, I should set ...

Re: Particle dispersion model of Code_Saturne

Hello all,

I'm still looking for the answers of my question which was: Which is the theoretical model of particle turbulent dispersion if I activate IDISTU = 1 in uslag1.f90? I cound'nt find the answers in theory guild of CSv4.0.

Thanks you for your help.

How to add source code written in c++

Hello all, I'm using CSv4.0. I has a vey basic question i think. I would like to use the cs_user_postprocess.c instead of GUI. When I copy the source code cs_user_postprocess.c from /SRC/REFERENCE/ to /SRC, should I also looking for all the "local headers" in cs_user_postprocess.c and put ...

Re: Post-traitment with groups of particles.

Hello, Im using Paraview4.3.1. I checked that the Par_vel_group__1 is a scalar and not a vector (I see that all the statistic variable of particulate phase on Eulerian mesh is a scalar). For more informations, all the scalar that I obtained related to particulate phases are: - Part_vol_grp__1 (Volum...
