Hi,
I was wondering if there is any update on this?
Best regards,

Hello Developers, I am running a closed cavity case with variable density (using ideal gas) to model free convection. Do I need to add any extra terms in the momentum equation to make it work ? For example when solving the same problem with constant density I use Boussinesq approximation and add the...

Hi,
I am using 7.1.2 version. May I ask how can I call previous time step values in User subroutine in C?
kind regards,

Hello,
I used the ideal gas equation to define pressure gradient in terms of density and temperature to get an implicit source term, this solved the problem.
Thanks.

Hi, I am Running 2D convergence nozzle with Enthalpy equation in version 7.1.2. the area ratio is 4 so the pressure and velocity change along x direction is significant. The Enthalpy equation described in theory guide page 17 is as follows: Screenshot (13).png here dp/dt is the lagrangian derivative...

Hi,
Got it, thanks.

Hi, I am using Code_saturne version 7.1.2. and trying to solve 2D convergent nozzle. I met with the following error. { Symmetric Gauss-Seidel: error (divergence) solving for TempK Call stack: 1: 0x14e241e721da <cs_sles_it_error_post_and_abort+0x8a> (libsaturne-7.1.so) 2: 0x14e241e67322 <cs_sles_solv...

Hello,
Got it, thank you.
May I also ask how can I call rotation velocity and axis if I am using Coriolis source term option in body force in GUI?
Best,
Hyder.

Dear Developers,

I am using frozen rotor model and I want to call the rotation axis and velocity from GUI to my user subrutine in C.
what function should I use? Thanks!

Kind regards,
Hyder.
