How does this soft handle 3D msh, such as C3D8 C3D4？

I'm looking for information in the format of gmsh output .inp file。

It will not work. In the source code there is conversion dictionary:
'C1D2':'B31', # 2 node beam
'T3D2':'B31', # 2 node beam
'C1D3':'B32', # 3 node beam
'T3D3':'B32', # 3 node beam
'C2D3':'S3', # 3 node shell
'CPS3':'S3', # 3 node shell
'C2D4':'S4', # 4 node shell
'CPS4':'S4', # 4 node shell
So, the script understand only beams and shells.
