If the common grid is regular, you can use Construct, to generate it. You
could also warp that grid (i.e., Mark positions->Compute->Unmark), if you
need to.

Let us consider example: two data fields on domain [0,1]x[0,1]; first
data have mostly coarse grid which is refined on left side of the
domain, the second data have grid refined on the right side. When I use
Map as
field1 field2
| |

----| |----
| |
Map
I get the first data on the second grid (refined on right side), but I
want to get data on the "common" grid refined on the both left and
right sides. How can I construct such common grid from field1 and field2
so that it is suitable to pass as second argument to Map or Regrid?
Best regards,
