Python Wave Finite Element

pywfe - a python package for the wave finite element method

This package implements the Wave Finite Element Method (WFEM) in Python to analyse guided waves in 1 dimension. Initially Written to analyse mechanical waves in fluid filled pipes meshed in COMSOL.

Currently only works for infinite waveguides.

The pywfe.Model class provides a high level api to calculate the free and forced response in the waveguide.
