- There's the diffusion eqn. in 2-D given by (all d's are partials):
-
- D d^2{C}/dx^2 + D d^2{C}/dy^2 + V dC/dx + V dC/dy = dC/dt
-
- I want to use the method of moments to get at D (2^nd rank tensor) and V.
- For the case of a single dimension, one could multiply by x^N (or y^N)
- and then using the chain rule trick get these two. How do I get these
- two creatures in 2-D ?
