Hi Adrain,
First of all, thank you for helping me out here.
When run in serial, the current code works almost correct, just that it did not copy at x=xMax plane and at the edge (xMin,yMin) https://www.dropbox.com/scl/fi/dcyze2b6b745c389vldld/serialCopy.png?rlkey=wobmt9paxqqc0awidnfannffn&st=pjacrhww&dl=0

However, when using AnalyticalFfromSuperF3D<T,T> uAnalytical(coarseU, /*communicateToAll =*/ false, /*communicateOverlap =*/ true); for serial run, it fails citing “double free or corruption (!prev) tri0570:1320121] *** Process received signal *** ”

Regarding the decomposition, I use 

CuboidDecomposition3D<T> cuboidDecompositionCoarse(
    cuboidCoarse, converterCoarse.getPhysDeltaX(), noOfCuboids);
CuboidDecomposition3D<T> cuboidDecompositionFine(
    cuboidFine, converterFine.getPhysDeltaX(), noOfCuboids);

I was wondering, how can we use same decomposition for both coarse and fine, since N and PhysDx are different?
