Hello,

I would like to know how to impose free slip boundary condition for a wall.
Is it possbile to do that with GUI setting?

Best regards,
Tsubasa

Hello Yvan, Thank you for that. That was what I wanted to know. Best regards, Tsubasa !!Dirichlet B.C for scalar transport: if(ntcabs ==ntpabs+1)then open (17, file='/home/tsubasa/Desktop/test/course/SRC/inlet_scalar_time_history.csv', status='old') read (17, '()') do i = 1, total_nstep read (17, *)...

Hello Yvan, Thank you for the advice. I remenbered it. I suceeded to impose time history of scalar value for species at inlet. I put them here, and if you find some mistakes, please let me know. integer i real i_scalar, i_direchlet_scalar real, save :: i_narray(50) ! should be change : total calcula...

Hello Yvan, Thank you for the advice. You mean if I assign "scalar1" as a name of scalar in GUI like in picture, I should write like this for the first line, right? integer :: f_id, keysca, iscal ... all field_get_id(scalar1, f_id) call field_get_key_id("scalar_id", keysca) call ...

Hello, Now I want to impose a value for scalar transport at inlet face by cs_user_boundary_conditions.f90, not GUI. Can we impose a value of scalar transport at inlet by cs_user_boundary_conditions.f90? At the same time I am imposing pressure value following the code. However, errors happend when co...

Hello, Now, I am trying to scalar transport simulation. I impose "1.0" of "Prescribed Value" for inlet condition, and "0.0 (zero)" of "Prescribed (outgoing) flux" for outlet condition. Here I am wondering that what is "Prescribed (outgoing) flux" for...

Hello Yvan, Sorry, I did not understand well about it. I checked Doxygen and now I understood how to access a field, and now I can find different behaviors by each schmidt number. I would like to show the code for someone who want to do same thing. void cs_user_parameters(cs_domain_t *domain) { cs_f...

Hello, Even if both "Specieas transpiort" and "Thermalmode" are active, I can see that "turbulent_schmidt" is set only for temperature, but not for "scalar1". Key: "alpha_turbulent_flux_id", values per field ---- Key: "turbulent_schmidt", v...

Hello Yvan, As you said, the simulation worked without error. However, even if I changed Schmidt number from 0.1 to 0.9 by this code void cs_user_parameters(cs_domain_t *domain) { cs_field_set_key_double(CS_F_(t), cs_field_key_id("turbulent_schmidt"), 0.1); } void cs_user_parameters(cs_dom...

Hello Yvan, No, thermal model is not active. I only set "scalar" in specieas transport. Do I need thermal model? In my case I need turbulent schmidt number (not turbulent Prandtl number) which is related to eddy viscosity and eddy diffusivity. Even though my simulation doesn't take hear in...
