HDMAmz_amazon grid fails in reading in mesh file

[ekluzek]

the HDMAmz_amazon grid is failing in reading the mesh file:rof/mizuRoute/meshes/HDMAmz_5x5_amazon_ctrcrd_cdf5_ESMFmesh_c20200731.nc

This is with using mapping files:

Maybe we need a polygon-centroid mesh file to read in? Is this grid important enough to keep?

[nmizukami]

If i remember, amazon HDMA used to use this unstructured mesh and do online remapping? so not using mapping files? Error seems to indicate some topology error in the mesh.

Also if I remember, this online mapping used to work, but not any more? if so, with some ESMF update (if any), it get pickier?

I guess a polygon centroid mesh with the mapping files could work.
