Calling CalculiX solver shows errors

[lcheng9]

A simple static structural problem using Calculix instead of FrontISTR. It errored out saying it couldn’t open the mesh file.

CalculiX does not support the mesh file path containing the space. We added a check for this scenario and prompt an error message if a space is found in the path.

Error: Mesh file path containing spaces are not supported for solver CalculiX! Please save the project to the path containing no space.
