Re: [Geopdes-users] refinement in multipatch geometries

[Rafael V. <va...@im...>]

Dear Alexis,
the .mat files are not supported in multipatch because the information 
from the nurbs structure is not enough, since you also need the 
boundaries and interfaces. But since this information does not change 
with the refinement, you can load the refined geometry with the function 
geo_load (without mp) for each single patch. This is exactly what is 
done in the examples in geopdes_elasticity/multipatch.

Regards,
Rafa
