Hi,

I'm trying to perform some remapping between two different topologies.

Is anyone aware of any problem in running parallel using nearest as interpolation method? Even remapping on the same topology is not working (in single core does). It seems that intersection and matching are working both single and parallel.

I want to precise that there are no errors, the process starts and stays forever at this stage:

Creating cellsToCells between source mesh and target mesh region0 using nearest
cellsToCells: Calculating couplings between 990448 source cells and 995332 target cells

in sigle core this step is performed in about 20s.

Thanks!!

No clues on this?

Can you please elaborate on what you are trying to accomplish?

I am lost in translation. Thx.

Thanks for taking time to check my issue.

What I'm trying to do is basically a mapFieldsPar in parallel (decomposed source and decomposed target) using nearest as mapMethod, mainly to reduce the execution time.

I made some tests and managed to use, without any problem, intersection and matching, however the first takes lots of time and the second requires a 1:1 correspondence between cells, that is not my case. Consequently I'm trying to use nearest without success.
