Non-conforming grid #40

Open Watchmojo opened 2 years ago

Hi,

Does SNaC support hanging grids at the interface between blocks, i.e., non-conforming grid?

Thanks

Hi @Watchmojo,

Currently, that is not supported. The "assembled" multi-block grid needs to be structured.

This extension could be possible at a later stage with a bit of work (fortunately, the multigrid solvers of hypre support non-conforming structured grids in its semi-structured interface (SSTRUCT), so one could still use this library for the Poisson solver).

Thank you for the information.
