A fast Q4 finite element formulation #17

Open PolymerGuy opened 4 years ago

PolymerGuy commented 4 years ago

We need to have a classical Q4 finite element formulation which can handle arbitrary meshes, is very fast and easy to use.

Suggestion:

Q4 support only
Direct inversion of the shape functions when updating references
Should support a standard mesh format such as .msh?
Visualization should utilize only the data at the centre of the elements and interpolate across boundaries using splines?
