Netgen/NGSolve is a high performance multiphysics finite element software. It is widely used to analyze models from solid mechanics, fluid dynamics and electromagnetics. Due to its flexible Python interface new physical equations and solution algorithms can be implemented easily.
At least one dependency seems to be missing from ngsolve_6.2.2102-0~ubuntu20.04.1_amd64.deb from ppa:ngsolve/ngsolve: some (all?) of the ngsolve and netgen-related shared libraries have a dependency on libpython3.8.so.1.0, but although python3 is listed as a dependency, libpython3.8 is not. (Actually it should probably be libpython3.8-dev)
