abageotests
A package to generate and execute python scripts of abaqus models of geotechnical tests.
Dependencies
In order to use this package, you need to install the numpy and matplotlib package:
pip install numpy
pip install matplotlibAnd furthermore, install abaqus properly, and link the FORTRAN compiler to abaqus, and add the abaqus commands directory to the system path environment.
And then install this package:
pip install abageotestsYou can also find this project in abageotests · PyPI.
