This Numerical Method is never going to work for
I have proved it for the 1-D case. But 1-D is embedded in 3-D.
So the result is
valid for 3-D as well.
Nevertheless, there is ongoing research on this topic,
There exist only two flavours for grid refinement
and grid coarsening: DoubleGrid and
The distinction between Continuous and Discrete is only gradual,
- Least Squares Finite Element Method.
Can only be formulated properly as a
Finite Elements and Finite Differences.
Two applications: Ideal Flow in
The concept of Dual Elements is important with L.S.FEM.
Unification of Finite Elements and Finite Differences for
Convection and Diffusion can be accomplished via
