[MOAB-dev] MOAB & periodicity

[Grindeanu, Iulian R.]

Hello,
There is some support for periodic meshes through SCDInterface;
So for example, a structured torus mesh has 2 periodicities, and it can be loaded in parallel, and partitioning and ghosting can happen at reading time; a sphere mesh (that appears in climate data) has one periodicity;
the mesh is though structured, and moab can handle ghosts pretty well for those types of meshes.
I am not sure though if it would fit your purpose;
You said your mesh is unstructured? Which would be a problem for SCDInterface

Dear all,

I am thinking about using MOAB as the basis for a cell-centered (unstructured)  finite volume solver. An important feature for me is to be able to handle periodicity (translational & rotational). As far as I understand, this is not directly possible with MOAB but I am wondering how difficult it would be.

What I would like to do is have "periodic ghost" cells that I would handle as the standard ghost cells (except I would possibly apply a rotation to the vectors after the data is exchanged for rotational periodicity)

How difficult do you think it would be to implement it? Do you have any example that implement similar operations?

Best regards

Xavier
