code_saturne User's Forum

Hello,

I would like to change the particle drag law in v4.0.5. The User Manual says the particle relaxation time maybe modified in subroutine "uslatp". I don't see this file in /USR/REFERENCE. Is it embedded in another file? Thanks.

Hello,

I think that the subroutine that you are looking for is in /REFERENCE/cs_user_particle_tracking.f90

Also you can check /EXAMPLES/cs_user_lagrangian_particle_tracking_module.f90

Regards,

Luciano

Yes. Thank you.
