General-purpose finite element solver - pyfe3d#
The pyfe3d module is a general-purpose finite element solver for structural
analysis and optimization based on Python and Cython. The main principles
guiding the development of pyfe3d are: simplicity, efficiency and
compatibility. The aimed level of compatibility allows one to run this solver
in any platform, including the Google Colab environment.
