preCICE-adapter for the open source computing platform FEniCS.

Installing the package

Using pip3 to install from PyPI

It is recommended to install fenicsprecice from PyPI via

pip3 install --user fenicsprecice

This should work out of the box, if all dependencies are installed correctly. If you face problems during installation or you want to run the tests, see below for a list of dependencies and alternative installation procedures

Clone this repository and use pip3

Required dependencies

Make sure to install the following dependencies:

Build and install the adapter

After cloning this repository and switching to the root directory (fenics-adapter), run pip3 install --user . from your shell.

Test the adapter

As a first test, try to import the adapter via python3 -c "import fenicsprecice".

You can run the other tests via python3 setup.py test.

Single tests can be also be run. For example the test test_vector_write in the file test_write_read.py can be run as follows:

python3 -m unittest tests.test_write_read.TestWriteandReadData.test_vector_write


FEniCS is suddenly broken: There are two known issues with preCICE, fenicsprecice and FEniCS:

  • If you see ImportError: cannot import name 'sub_forms_by_domain' run pip3 uninstall -y fenics-ufl. For details, refer to issue #103.
  • If you see ImportError: cannot import name 'cellname2facetname' from 'ufl.cell', refer to issue #154.
  • If you see ModuleNotFoundError: No module named 'dolfin' and have installed PETSc from source, refer to this forum post. Short version: Try to use the PETSc that comes with your system, if possible. Note that you can also compile preCICE without PETSc, if necessary.

If this does not help, you can contact us on gitter or open an issue.

Development history

The initial version of this adapter was developed by Benjamin Rodenberg during his research stay at Lund University in the group for Numerical Analysis in close collaboration with Peter Meisrimel.

Richard Hertrich contributed the possibility to perform FSI simulations using the adapter in his Bachelor thesis.

Ishaan Desai improved the user interface and extended the adapter to allow for parallel FEniCS computations and 3D cases in certain scenarios.
