According to the User’s Guide, grid refinement is only available for 2D cases. However, in looking through the source, I’ve found things like multiGrid3D.cpp that implies some level of implementation. I would like to work on an adaptive refinement scheme around an STL geometry. To start, I would want to have a coarse grid, with high refinement around a geometry and medium refinement in a wake region. Does Palabos 1.4r1 have the capabilities to do this? Are there implications to running a 3D multi-grid in parallel? Thanks!
