ngstSpaceKit is an add-on to ngsolve and ngstrefftz, and provides a collection of finite element spaces. The goal of this project is to explore possibilities of the conforming Trefftz Method, and provide concrete example uses for it.
Implemented Spaces
ngstSpaceKit implements a series of well-known finite elements, that are not yet implemented in ngsolve:
On top of that, there are other exotic spaces defined:
- a weakly H1-conforming element, with the option to use the inner dofs with an embedded Trefftz formulation
- an H(div)-conforming element, with the option to use the inner dofs with an embedded Trefftz formulation
- a Stokes mixed element, where the velocity part is weakly H(div)-conforming, and the remaining dofs adhering to a Stokes embedded Trefftz formulation
- a P1 / Q1 Immersed Finite Element Space, which is suitable to solve interface problems on a domain with a cut. Refer to Lin et al. for a proper introduction of the Immersed Finite Element method.
For demonstration purposes, there are some spaces implemented, which already have a native ngsolve implementation:
