Change dof_map

–1 vote

Hi folks,

Just a quick question about dof map. Is there any way to change the dof map associated with a simple rectangle mesh?

Any help is deeply appreciated.

Thanks,
Mo

It's not clear what you want, but you can create your own dofmap. It just needs implement the dolfin::GenericDofMap interface.

Hi Garth,

Thank you for your comment. Creating my own dofmap is exactly what I need. Is there any example about creating my own dofmap via dolfin::GenericDofMap interface?

Thanks,
Mo

You just need to create your own C++ sub-class of dolfin::GenericDofMap that implements the pure virtual function in dolfin::GenericDofMap (see dolfin/fem/GenericDofMap.h).
