Using parameter in Mesh definition

Hello,

Is it possible to use a parameter in the edge subdivision for the mapped mesh definition.

I have a full hexa mesh of a block , and the mesh density is defined by the edge subdivision.

Because of the volume decompostion, I have lot's of mesh edge definition (subdivision), and if I want to check the mesh sensibility, I have to modify each set of edge subdivision.

By involving a parameter, I could easily work from coarse to fine mesh.

edge_subdivision_1= 2*k

edge_subdivision_2= 5*k

etc...

Thanks for any trick
