[Nek5000-users] How to create mesh?

[Kerkemeier Stefan]

Hi,

> The first problem is how to compile the tool such as genmap and genbox ?
You can compile the tools using the maketools script (similar to makenek).

> Secondly, can the mesh created by Gmsh(an opensource FEM mesh generator) be used by nek5000?
No we do not support GMSH. 
Please note that GMSH is a tet-mesher and NEK5000 does only support quad/hexahedral elements.

Currently we have the following options to generate a mesh:
- genbox:  simple box mesh
- prenek:  GUI which can be used to create more complicated meshes
- by hand  basically you have to provide the corner points of the elements + curved sides (check Wiki for more details)
- MOAB:    we are currently working on a MOAB interface to read meshes from Cubit (http://cubit.sandia.gov)

hth,
