aperi-mech_test

NOTE: This repo is dead and is just around for parts.

Regression tests for aper-mech, an open-source platform for computational mechanics.

Prerequisites

Some tests build meshes using gmsh and then convert them to exodus format using a combination of meshio and exodus.py from seacas. Running in parallel requires mpi and checking results differences requires exodiff from seacas. Some packages can all be installed using spack and others are better installed with conda or pip.

Install Spack

Follow the instructions at https://spack.readthedocs.io/en/latest/getting_started.html. In short, install the spack prerequisites, clone spack, and source the script for shell support.

Find System Tools

# Add system compilers. e.g. gcc
spack compiler find

# Use external tools. e.g. cmake
spack external find

Create a Spack Environment

# Create and activate a spack environment for the project
spack env create aperi-mech_test
spacktivate aperi-mech_test

Add and Install Required Packages

# If needed, specify a specific compiler. For example, add `%gcc@10.5.0` at the end of the `spack add` commands
spack add seacas
spack add openmpi
spack add py-pip

# Install Packages
spack concretize -f
spack install

Add system package prerequisites

# Needed by gmsh
sudo apt update
sudo apt install libglu1-mesa
sudo apt install xorg

Install gmesh and meshio

# Be sure to match the pip version with the python version.
# E.g. run `python --version` and `pip --version` and check they match
pip install gmsh
pip install meshio
pip install netCDF4 # needed by meshio
