Hi,

Do you mean RHS Sweep Reconstruction in the GUI ??


Thank you.

Hi,

I have understood that Code Saturne do have blended scheme under numerical parameters.
But I only found upwind, centered and SOLU in the GUI.

Please help.

Thanks!

Hi,

Yes I followed step by step as in tutorial, only the temperature contour looks similar.

Thanks.

Hi,

Anyway, I got this when I view the velocity in ParaView. Is this acceptable ?

Thanks

Hi all, I am trying to see the temperature distribution in a 3D rectangular box filled with air due to natural convection. The six walls boundary conditions (temperature value) will be defined. I did it using Boussinesq Approximation . However, I wonder if the velocity is normal? Anyone can help if ...

Hi,

Ok got it! Thanks a lot!

By the way, mind telling how the tutorial come to a CFL number of 8? I have searched the forum, but seems non really stating the formula to get this number ?

Thanks again!

Hi,

Thanks for your help,
I have corrected the value of beta. But the flow only starts when I use tref=300 as you recommended early. I cannot understand why have to start with 300 K ?

Also, for convergence checking, am I only looking for the magnitudes of Norm_residual ?

Thanks much!

Hey,

Thanks for your help,

I have tried, but wonder why my solution not converging ?
Anything else i did wrongly ?? I attached the study zip file.

Pls help~ thanks much.

Dear all,

I am trying out the tutorial 3 that written based on version 3.0, but I am using version 4.0.5 on windows. May I know how should I call the use of "cs_user_physical_properties" in the GUI after I selected the "variable" choice for density ???


Thanks!

Hi,

Then the boundary conditions of a box that placed under the sun, I just have to define the six planes temperature (prescribed value) as the WALL boundary condition right ?

TQ.
