| Sep 18, 2018 at 17:19 | comment | added | BlaB | This will be relatively complex, because FEM solvers for structures are generally written for unstructured meshes whereas LBM uses a cartesian grid with conformal decomposition. As far as I am aware, there is no such framework that exists. You might want to look into open source LBM framework such as OpenLB and Palabos and adapt them consequently... I think that the fact that LBM is an explicit method will however greatly hinder your efforts. | |
