FEniCSx for polymers

FEniCSx for polymers is simple API for FEniCSx - finite element analysis framework for python. See https://github.com/FEniCS/dolfinx. Fenics package is facade for low level dolfinx lib and contains high level functions for quick set up general structures for FEniCSx solvers. I created docker image with all necessary dependencies.

This is my university course work of mathematical modeling of diffusion processes in multicomponent photopolymerization system. See for another information about chemical aspects: https://github.com/EnglishBeach/COMSOL_polymers.

Structure

  • fenics - API forlder:
    • operators - functions, different operators from ufl and nessesary clases for set up study
    • express - constructors and tools for simple build and configure common studies
    • distributions - module collecting different form distributions
  • Solver.ipynb - solver for diffusion processes of photopolymerization
  • parametrs - parametrs for 1D and another tasks with boundary conditions and so on

Usage

Easiest way is Docker images:

docker run -ti englishbeach/fenics:v0.1

For network:

docker run --init -ti -p 8888:8888 englishbeach/fenics:v0.1  # Access at http://localhost:8888

Changes:

  • corrected complicated parametrs set up
  • unify high and low level variables realisations: ufl.Expressions, fem.Functions, fem.Consstants and pythonic functions, floats
  • new tools for efficient solving and viewing results

Plans:

  • Fix database for recording results
  • add setup for fenics package
  • add 2D support and relevant functions
  • add more API elements for another FEniCSx features
  • fix some bad errors in dolfinx functions (infite circle trying compile ufl form in function)
