Description

A single-element finite element compatability layer in Python 3. This Single Point Simulator (SPS) uses the NumPy F2PY module to compile Fortran based (V)UMAT material models from Abaqus/Standard or Abaqus Explicit. Then, with a simple material property input file (in .toml or .json format), this tool quickly computes these single-element models and provides tools to visualize the results.

Installation

python -m pip install singlepointsim

Basic Usage

python -m singlepointsim <inputfile>

See example_input.toml for an overview of how to format the input file. (.json input format is also accepted by the singlepointsim)

Recommended Usage

Consider a directory containing the desired (V)UMAT fortran file, foo.f90 In the same directory, create input.toml using the same format as example_input.toml as shown in this github repository. Then, simply running:

python -m singlepointsim input.toml

should compile the (V)UMAT to a .so or .dll if it is not already compiled and should call on this object to run analysis. Results will be stored in a .csv file in the desired "results" directory, as given by input.toml (or the present working directory if not specified).
