I am trying to get a 5:3:1 aspect ratio meshes with the method of Cartesian, by specifing the aspect ratio. But it always failed at the error message as below.

Cartesian mesher failed to create mesh
Loading domain "1201_BFCmesh.uns" ...
1201_BFCmesh.uns: 1201_BFCmesh.uns: error opening file 1201_BFCmesh.uns : No such file or directory

The manual tells that, the Cartesian mesher does not require an existing surface mesh and will ignore meshing parameters defined to control local surfaces. Then why prompt that no .uns file exists?

BTW, is there another way to generate a slim mesh except blocking? I am modeling a plane-like domain whose depth is much less than the length and width, and extruded mesh can not be used. But general tetra mesh would go to a too many cells solution. Specifing the aspect ratio would lower down the mesh size, but I always failed to get a Cartesian mesh.
