Yade-OpenFOAM-coupling

An OpenFOAM solver for realizing CFD-DEM simulations with the Open Source Discrete Element Solver Yade-DEM.

• Fast mesh search (including range based search) based on k-d Tree algorithm, faster than the original Octree search offered by OpenFOAM (mesh.findCell, mesh.findNearest).
• Gaussian interpolation of field variables.
• Simple point-force coupling (icoFoamYade) solver
• Full 4-way coupling (pimpleFoamYade) solver (under validation).
• Documentation : https://yade-dev.gitlab.io/trunk/FoamCoupling.html
• Examples : https://gitlab.com/yade-dev/trunk/tree/master/examples/openfoam

UPDATE (27 Nov 2019)

• Full parallel coupling between Yade and OpenFOAM (as Yade is now fully parallel based on MPI)

Prerequisites : Latest Yade git version with the FoamCoupling engine (https://gitlab.com/yade-dev/trunk). OpenFOAM-6.

Build

• Compile the lib FoamYade and solver icoFoamYade :
  • ./Allwmake

Running

• Copy example to $FOAM_RUN
• Create a symbolic link
  • ln -s /path/to/your/yade/install/bin/yade-exec libyade.py
• Run
  • cp -r example_icoFoamYade /to/your/run/dir
  • mpiexec -n 1 python scriptYade.py : -n 2 icoFoamYade -parallel
