Hello,

I created mesh of a complicated geometry in Ansys meshing. It consists of more than 10 millions elements. Then in CFX I use mesh tranformation (rotation) to create full domain. So the full domain consists of more than 100 millions elements.

1) Once I drag the mesh into the CFX, a .cmdb mesh format is created. Then after the mesh is copied by the rotation, the periodic boundaries are glued together (they are interior) which is fine.

2) If I export the mesh in .msh format and then this .msh is imported into CFX, the periodic boundaries are not glued and the volumes are isolated. I tried to change the settings of mesh tolerance and double nodes removal etc and nothing works.

The reason why I want to use .msh format is that .msh does not include all faces, it includes only my name selections. Because when using .cmdb mesh in CFX, the calculation does not run due to memory issues. I read that it could be caused by the high number of faces and using .msh could be the workaround. But I cannot glue the segments.
