MeshPy: A general purpose 3D beam finite element input generator

MeshPy is a general purpose 3D beam finite element input generator written in python3. It contains basic geometry creation and manipulation functions to create complex beam geometries, including rotational degrees of freedom for the beam nodes. It can be used to create input files for the following finite element solvers:

4C (academic finite element solver)
Abaqus (commercial software package)

MeshPy can easily be adapted to create input files for other solvers. MeshPy is developed at the Institute for Mathematics and Computer-Based Simulation (IMCS) at the Universität der Bundeswehr München.
