[ncl-talk] ESMF_regrid

[Laura Fowler]

Hello:

I have been using ESMF_regrid to regrid an unstructured MPAS mesh to a
latitude-longitude grid, including to regrid variable-resolution meshes
(i.e. the coarse mesh has a resolution of about 30 km and the refined mesh
has a resolution of about 6 km). Using the same script to regrid a
variable-resolution mesh which has a resolution varying between 15 and 3
km, I get the following SIGSEGV error:

(0) ESMF_regrid_gen_weights: number of processors used: 1

(0) --------------------------------------------------

(0) ESMF_regrid_gen_weights: the following command is about to be executed
on the system:

Since the same ncl script works for a lower resolution mesh, is it possible
that ESMF_regrid does not handle a high resolution mesh?

Thanks,
Laura
