Good Nigth , My name is Luis Rojas . I have a Hexahedral Mesh , this has 36727 elements . I want to do an análisis of this mesh with the double of this. Can you help me to know how to change the number of elements of my mesh?

Thanks

See the photo of the mesh here.

Quick questions:
  1. Do you want to "refine the mesh" or do you want to "renumber the mesh"?
  2. If you want to "refine the mesh", why don't you generate a new one in Salome?
  3. The image you provided the link for, is a tetrahedral mesh, not an hexahedral mesh. Did you provide the incorrect image?

To refine the mesh, you could try refineMesh too, if re-meshing is too complicated.

The version I am using is windows 10 Version 15.06 thanks , The real question of this forum is ... if i have a Hexaedral mesh with n volumens and edges.. etc.. how I can change that number of faces and volumens changing the 1D and 2D hypothesis.

I am not sure what the Windows version has to do with this.

To run a 2D case, you need 1 cell in the third direction only, while for 1D cases. you need 1 cell only, in the second and third direction.
