sympde is a Symbolic calculus library for partial differential equations and variational forms. It can be used to have similar capabilities as the fenics project, by extending and writing your own printing functions.
An example of use can be found in psydac or gelato.
Simply run, for a local installation:
pip3 install --user sympde
or:
pip3 install sympde
for a global installation.
Standard mode:
python3 -m pip install .
Development mode:
python3 -m pip install --user -e .
Because many important features of sympde are only tested in psydac, new PRs must also be tested against the test suite of psydac. This can be done by opening a PR in psydac where the only change consists of installing the corresponding branch of sympde.
For instance to test a new sympde branch called my_feature, the following
lines can be used in the file .github/workflows/continuous-integration.yml of psydac:
- name: Download a development version of sympde
working-directory: /tmp
run: |
wget https://github.com/pyccel/sympde/archive/refs/heads/my_feature.zip
unzip ./my_feature.zip
python3 -m pip install ./sympde-my_feature
