Uncorrected mapping with NCmesh #46
Comments
Hi @sungho91 the methods We haven't tested Remhos with NC meshes, but I expect some combinations to work. I'll try and let you know soon. You can also try by simplifying the setup (disable the monotonicity), and then go back incrementally. For example |
According to my quick couple of tests, introducing a low-order solver prohibits advection between coarse- and fine-mesh regions. |
I'm on travel this week, but I'll take a look when I come back. |

Hi all,
I'm incorporating Remhos into my code to remap the L2 fields after remeshing.
I believe the remapping is functioning correctly with the conforming mesh, but I'm encountering some issues with a non-conforming mesh.
In the case of a conforming mesh, the mesh simply moves, and the field does not move because they are advected together. However, with a non-conforming mesh, the shape of the field is altered, leading to incorrect mapping (see attached image).
This is obvious when I use the example of Remhos.
I typed
mpirun -np 8 remhos -m ./data/cube01_hex.mesh -p 10 -rs 1 -o 2 -dt 0.02 -tf 0.8 -ho 1 -lo 4 -fct 2
but I modified element attributes of 1st and 2nd element to two and Remhos like this way. You can see non-conforming mesh and final remapped field is highly distorted. I think advection is prohibited between coarse- and fine-mesh regions.Any comments would be greatly appreciated.
