1D shallow water equations #494

Closed jshipton closed 7 months ago

jshipton commented 7 months ago

This PR adds an equation class for the 1D shallow water equations and the required 1D transport and diffusion terms.

To Do:

make example into a KGO test instead of an example
define linearisation
this won't work with SIQN without another bespoke linear solver - I'd rather not write that!

@tommbendall any comments / requests?

jshipton commented 7 months ago

aha, we used to make the velocity a vector with just one component... @tommbendall would you like to keep it like this (to test the usual code for the transport forms) or shall I change this test to use the new 1D forms?
