Coupled Simulation of OpenFOAM and Flowmol using CPL library
<p>A video showing proof of concept for nucleation of a bubble using coupled molecular (MD) and computational fluid dynamics (CFD) simulation. The MD solver (Flowmol but similar results have been shown with LAMMPS) is used to simulate a wall notch and grow the initial bubble before passing density, Volume of Fluid (VOF), velocity and temperature fields to a CFD solver (OpenFOAM). Coupling is handled by CPL library but with MD simuilation pre-run (on the Young supercomputer) and loaded by a Python script which then exchanges the data using CPL library calls (based message passing interface (MPI) to mimic the exchnage in the same way the MD would. This is therefore only one-way coupling with MD data passed to the CFD but not constraint applied.</p>
