fenicsx_polymers's Introduction

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)
