[Dune] How can I read a curved surface from gmsh?

[Timo Koch]

Dear Dmitry,

You cannot do that with UGGrid. You could use FoamGrid 
(https://gitlab.dune-project.org/extensions/dune-foamgrid) and probably 
AluGrid (https://gitlab.dune-project.org/extensions/dune-alugrid).

FoamGrid has two template parameters, the grid dimension and the 
coordinate/world dimension, you want Dune::FoamGrid<2,3>.

Best wishes

Timo
