Error in the mesh file．

Amber0922 · June 7, 2023, 10:06

　Hi,
　I use the ICEM-CFD to get the mesh,　and it shows
＂Error in"stdustring　CCGNSMeshReaderFVM:GetCGNSElementTyp e(ElementType_t, int&)"
Line elements detected in a 3D mesh.Please remove.＂
＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿
　In ICEM, I have separated the entire lines and points into different parts. Could this be the cause of the issue? If so, how can it be resolved?
　 Thank you for any assistance!

Yes, this is the issue. For a 3D mesh, SU2 expects one single 3D interior volume augmented with 2D surfaces which make up the boundary. You cannot have 1d elements in a 3d mesh as separate entities (in SU2).
