Nonconforming FE space

Dear developers,
I noticed that nonconforming FE space is not defined in ngsolve.FESpace (by looking through help(FESpace)), but I can find NonconformingFESpace defined in fespace.hpp. May I ask if and how I can construct the nonconforming FE spaces in my programs?
Thank you!


you can create the nonconforming H1-FESpace by using

fes = FESpace(“nonconforming”, mesh)


Thanks for your help, Michael!
