Hello,

Necessary to solve the problem of modeling of axisymmetric flow in a conical channel. From the manual is not clear how to define the axis of symmetry. I already broke my entire head.

Please help.

Hello,

Code_Saturne only uses 3D meshes. For an axisymetric case, you need to extrude your surface mesh by rotation along its axis of symmetry, so as to obtain a mesh at least 1 cell thick; so you can use any axis you want.

For faces on the "base" or "extruded" base of the mesh, use symmetry or periodicity.

Thank you very much. Everything turned out. But not without problems.
