Hello, I figured out how to do the interpolation using GridTools:get_finest_common_cells(). But I ran into this error shown in the attachment. Two possible reasons:
1. The way I create the two triangulations from the same coarse grid is not correct. 2. The function, get_finest_common_cells(), does not work for distributed triangulations when the two grids are not identical. If it is the first case, any example would be appreciated. If it is the second case, is there other solution?
