Hello, In fact in version 4.0 you can apply a free surface boundary condition directly in the GUI, if you have switch on the ALE module. For this boundary condition to be valid, you also need to correctly give the gravity vector. It is possible to do it also in fortran subroutines with the "ity...

Hi, as already wrote Jacques, we have changed the writing of the diffusive boundary conditions coefficients. It is up to date in the theory guide. It was done for conveniency purpose and everything which was possible in 2.0 is in 3.0, just a matter of rewriting. By the way, it is formally forbidden ...

Dear Code Saturne team, I am using 3.0 version of the code. There is an error message that says, /home/projets/saturne/Code_Saturne/3.0/src/code_saturne-3.0.0/src/gui/cs_gui_mobile_mesh.c:890: Fatal error. Formula is null for ale. Call stack: 1: 0x2aef45dedd34 <bft_error+0x94> (libsaturne.so.0) 2: ...

Hi, here is a setting for a code-code coupling between fluid2 and fluid1: /*------------------------------------------------------------------------- * Coupling with instance "fluid2". * * - coupled faces of groups "coupled_boundary2" * - all cells available as location support *...

Hello James, to compute the gradient of any potential field (such as the pressure field) use grdpot, to compute the gradient of any scalar field which is not a potential (such as the Temperature) use grdcel, and to compute the gradient of vector fields (such as the velocity or the mesh velocity) use...

Dear Chengan, you are right when writing that it is not well described in the theory guide. The transport equation (and you can look at the code of the subroutine covofi.f90) of a scalar take into account a total diffusivity (which is K +K_T where K_T = \frac{\mu_T}{Pr_T} ). The equation of Energy i...

Dear Chengan, I'm not sure I understand well your question. If you select a LES modeling, then the continuity equation and the momentum equation and the transport equation for any scalar are those of the LES averaged variables. That is to say, you do not need to add any term to the transport equatio...
