make code more general to incorporate other internal and external meshes and boundary conditions for them
make code more general to incorporate other internal and external meshes and boundary conditions for them fix bug where loads/ prescribed displacements could only be positive
Closes #50
restructuring:
- new folder Sources/+specimen with subdirectories: +internal contains internal meshes (plate, ...); +external contains function which reads meshes from external files (so far gmsh import added)
- boundary condition setup subdivided into edge_boundaries (wherein edges can be defined for BCs) and node_boundaries (wherein the user can directly give node sets for BCs)
- deleted redundant files for the plate specimen
the changes/ generalisation necessitated changes in ALL input files, where mesh and boundary conditions are defined
