Hello Luciano and Yvan, I tried to do the meshs junction properly with a simple case between 2 cubes. Firstly, I tried with hexa meshs, and it's work correctly, when I make the junction in C_S or in Salome (build compound). Now, I'm trying to make the same thing but with complex meshs (NETGEN). I ha...

Hello Luciano, This is a good remark, I have changed the meshing netgen 3D-2D-1D for the diffuser and hexahedric (hexahedron i,j,k) mesh for the room and assembled it together, I think this is the best way, but the junction is bad and my simulation diverge (conjugate gradient). I would like to know,...

Hello Yvan, about the mesh quality, there are 11 poor meshs on 495 000 cells so the meshing is correct. Details about the mesh is in the attached file. I'm using for the gradient calculation method : "Iterative handling of non-orthogonalities", so I will try with the least square method ov...

Hello Yvan,

Thanks for your reply,

About the meshing, I used the alogoritm Netgen 3D-2D-1D in Salome.

About the buoyancy, the density is variable according the air temperature.

Hello, During a simulation of a air diffuser in a room, I have stranges velocities. I have already change mesh parameters and time step parameters, but I would like to know how can I check what is wrong ? In the listing file the Courant Number is correct and residual part too. About the Fourier Numb...

Hello Yvan,

Thanks, very useful.

Best regards

Hello, I'm using for my CFD studies the software Code_saturne for calculations and "Paraview" (4.0.1) for the rendering. When I see the results (see picture) The view is not smoothed but with rectangles/triangles corresponding to the meshing. I have tested the filter in Paraview "Smoo...

Hello Yvan,

Good job ! I have re-run the automatic installer in a clean directory and no error appear !


Thank you sincerely

Hello Yvan, Thanks a lot for your help, Now I can open Code_Saturne, I will work with Salome for the pre-processing, so I try to run the tutorial "Pipe", I export from Salome the file : "pipe.med" In code saturne, in the section "Calculation environment" I check the mes...
