Hi, I've been looking to compare some approaches to solving the biharmonic problem (mixed and primal weak forms) that appears in areas such as plate bending. The primal formulation requires a subspace of H^2 to be constructed.
It seems that when I try to declare something like: V_3 = df.FunctionSpace(mesh, "Hermite", None) I get the error: RuntimeError: *** Error: Illegal degree for creation of function space, not an integer: None And upon the declaration to: V_3 = df.FunctionSpace(mesh, "Hermite", 1) I get the error: ufl.log.UFLException: Degree "1" invalid for "Hermite" finite element, should be None I can see that the element has been implemented in both SyFi and FIAT, but has it been implemented in SFC/FFC and Dolfin? If not (and I'm not sure I have the skills to help, but would like to know) what needs to be done to finish the implementation through to the Dolfin level? Thanks for your help, Jack Hale Department of Aeronautics Imperial College London _______________________________________________ Mailing list: https://launchpad.net/~dolfin Post to : [email protected] Unsubscribe : https://launchpad.net/~dolfin More help : https://help.launchpad.net/ListHelp
