Setup
This case illustrates how to implement volume coupling in a simple toy problem. Two diffusion problems are coupled via volume terms. One domain (the source) has constant non-zero Dirichlet boundary conditions. The other domain (the drain) has Neumann boundary conditions and a zero Dirichlet boundary condition at the right edge of the domain. The quantity u flows from the source to the drain.
Configuration
preCICE configuration (image generated using the precice-config-visualizer):
Available solvers and dependencies
Both participants (Source and Drain):
- FEniCS. Install FEniCS and the FEniCS-adapter. Additionally, you will need to have preCICE and the python bindings installed on your system.
Running the simulation
FEniCS is used to run the simulation. Open two separate terminals and start the source and drain participant by calling the respective run script run.sh located in the participant directory. For example:
cd source-fenics
./run.sh
and
cd drain-fenics
./run.sh
in order to use FEniCS for both participants in this test case.
