Hello to the Precice community,
I want to develop a FSI code using Precice, the structural part would be solved by Calculix with its adapter and for the fluid the idea is to use a solver based on the Lattice Boltzmann Method (LBM) instead of the Navier Stokes equation.
Using LBM should not be a problem because at the end, I’m only interested by the forces applied to my structure like for a Navier Stokes solver. My real question is about the Data Mapping between both solvers. The LBM uses a Cartesian mesh which can’t be deformed during the simulation and Calculix uses its own mesh based on FEM. If I understand the Data Mapping tool allows to “project” the forces from my LBM Cartesian mesh on the FEM mesh.
The fact is that I have already implemented in my fluid solver the Immersed Boundary method (IBM) which basically is my ‘own’ data mapping tool.
For that reason, the goal of Precice would be to exchange the data like force and displacement between the solvers and make a strong coupling with sub-iterations but without the Data Mapping part.
I would like to know if this configuration is possible with Precice and if this is going to “simplify” the development of the adapter or if this require a lot of work?
