Create the grid big enough for both meshes and then use Map.
David
Hi, I have several rectangular 2D scalar fields (intensity vs. 2D coordinate, regular square grid), all with the same step size (i.e. they live on the same mesh, but in different areas and only partially overlap). I would now like to merge them into one field, so that I can e.g. transpose and and then average them. CollectMultiGrid does not create a single field as output, so doesn't work. When I try to first regrid the input fields on the same field made by construct, the areas where no data exist are not zero, but some interpolated value, and adding the input fields afterwards will add that interpolated intensity to the other patches. The approach with compute that works e.g. with merging two scalar fields that live on the same grid to obtain a vector field does not work, since the grids of the input fields are not the same and overlap at best partially. Making a large field encompassing the area of the input fields, filling it with zeroes and then trying to add the individual fields to it fails since the sizes of the grids do not match. So I ran out of ideas. Am I missing something obvious?
