void getfem::mesh_im::set_integration_method ( size_type  cv,
pintegration_method  pim 
)

Set the integration method of a convex.

Parameters
cvthe convex number
pimthe integration method, typically obtained with
getfem::int_method_descriptor("IM_SOMETHING(..)")

◆ read_from_file() [2/2]

void getfem::mesh_im::read_from_file ( const std::string &  name)

Read the mesh_im from a file.

Parameters
namethe file name.
