Remap suitable for RZ (Cylindrical co-ordinates)

[cjoycd]

Dear contributors,

I have been using the modified version of Laghos by implementing RZ (Cylindrical) geometry as well as multi-material formulations. Presently looking forward to implement a remap scheme using REMHOS miniapp. As far as I can understand, the RZ capability is not implemented with the present REMHOS version. I would like to know is there any future version planned to include this capability ? What are the changes that might required to make it compatible with RZ geometry (like changes in Convection Integrator, Mass Integrator, Trace Integrators, ....) ? Is there any documentation available ?

Thank you in advance

Hi Sijoy,

You're right, there is no RZ capability in Remhos. We don't plan to add this to the miniapp. We will also stick to a single-material formulation, to reduce complexity.

There is a branch (product-sync) that implements product remap, e.g., remapping mass while preserving the bounds of density. This is one approach to connect Laghos and Remhos, as derived in our ALE paper. This branch is still WIP, but it will be merged soon.

The only change to make RZ work would be to add the extra weight coefficient to all integrators. I expect that most methods won't require any other manipulations, although I haven't looked closely at all of them.

Dear Vladimir,

Thank you for the comments.
I will look forward to the version (product-sync) that implements product remap and try to implement the changes that are required for RZ compatibility.
