Hi & thanks.

I need adjacency with common edge.
Sorry, I don't know what is CDO.

Hi. Thanks admin. That solved it! Now i wanna ask you two more questions. 1_ Is there any function to get the adjacent or connected boundary face to an interior face? 2_ Is there any function to get the adjacent faces on a boundary face just like cs_glob_mesh_adjacencies which gives the adjacent cel...

Thanks admin. I have a mesh which is generated by extruding a 2d grid in z direction with 20 layers with equal spacing in z direction. So it has cubic cells and also is homogeneous in that direction. I found cs_glob_mesh->i_face_cells which gives the two cells that are adjacent by their common inter...

Thank you mr.Fournier,
I just want to calculate DX+ & DZ+which needs the distances between two neighbour cells.
Is this available in cs or i shoud use cs_glob_mesh_adjacencies() and some loops?
For example, how does the cs calculate CFL number itself which needs the DX?

Hi there!
Is there a way to find the neighbor of a cell in a desired direction in cs? Example: i have cell #1 and i wanna find it's neighbour cell in z or y direction.
I found cs_geom_closest_point() but has no options for selecting in the desired direction.
Thanks

Thanks admin.
My grid is structured then hence the solver is unstructured you mean i have to get the values of left hand side -. right hand side by the coordinates of the cell and the distance between centers? That will be reallly time consuming and inaccurate

Hi guys. I wanna get the velocity of the previous and next cells and multiply them e.g:


is it possible in this code? thanks

Hi admin. i think i'm not very expert in codesaturne to test this coupling! by the way thank you.

Hello Thank you much! I think it's now much easier in code saturne than ANSYS FLUENT :mrgreen: It's working now. Two more question: 1. Can I set up two different models for these two parts? For example Laminar + LES? 2. Code saturne is about ten times faster than ANSYS FLUENT while the solver precis...

Hi guys! We have a mesh which contains two parts. The first part has 50 elements in z direction while the second part has 10 elements in that direction this is done to save the number of elements in the region where the flow is supposed to be inviscid and not turbulent. Also the length is equal in z...
