Well, you can create a composite field (i.e., what Partition does on an SMP
machine for modules to run in parallel) or a multigrid.  The composite
field would be appropriate for tiled images, DEMs, etc.  The latter
supports overlap and you can indicate what part of the other grid(s) to
ignore.  It can be used for data from simulations on multizone or nested
grids.

Subject:  [opendx-users] How to merge grids?



Is there a way to adjoin grids in DX without interpolation?

I have rectangular sections of a very large gridded dataset (regular
positions/connections) stored on disk.  Same deltas, but each has its own
origin.

I want to load 2 different adjacent sections and combine them into one
regular grid:


        0 -----> (m-1)       m -----> (2m-1)      0 ---------------> (2m-1)

         ----------           ----------           --------------------
        |          |         |          |         |                    |
        |          |    +    |          |    =    |                    |
        |          |         |          |         |                    |
        |          |         |          |         |                    |
         ----------           ----------           --------------------

Essentially, just re-interleave the data arrays.

How?  (I feel like I must be missing something obvious.)

Thanks,

Randall
