Welcome to PSYDAC

PSYDAC is a Python 3 Library for isogeometric analysis.

Requirements

• Python3:

  sudo apt-get install python3 python3-dev

• pip3:

  sudo apt-get install python3-pip

• All non-Python dependencies can be installed by following the instructions for the pyccel library

• All Python dependencies can be installed using:

  export CC="mpicc"
  export HDF5_MPI="ON"
  export HDF5_DIR=/path/to/hdf5/openmpi
  python3 -m pip install -r requirements.txt
  python3 -m pip install -r requirements_extra.txt --no-build-isolation

Installing the library

• Standard mode:

  python3 -m pip install .

• Development mode:

  python3 -m pip install --user -e .

Uninstall

• Whichever the install mode:

  python3 -m pip uninstall psydac

Running tests

export PSYDAC_MESH_DIR=/path/to/psydac/mesh/
python3 -m pytest --pyargs psydac -m "not parallel"
python3 /path/to/psydac/mpi_tester.py --pyargs psydac -m "parallel"

Speeding up Psydac's core

Some of the low-level functions in psydac are written in python in a way that can be accelerated by pyccel. Currently, all of those are in psydac/core/kernels.py and psydac/core/bsplines_pyccel.py.

cd path/to/psydac/core
pyccel kernels.py --language fortran
pyccel bsplines_pyccel.py --language fortran

Mesh Generation

After installation, a command psydac-mesh will be available.

Example of usage

psydac-mesh -n='16,16' -d='3,3' square mesh.h5
