example(gwt-adv-schemes) Example that demonstrates the different advection schemes

[Manangka]

This examples demonstrates the different advection schemes available in MODFLOW.
It includes the newly added UTVD scheme.

Three waves are advected through a square domain:

• sin²-wave: This is a smooth wave which should demonstrate 2nd order convergence for the Central and UTVD scheme
• block-wave: This should demonstrate that the TVD limiters fall back to a first order method in order to prevent oscilations
• step-wave: See block wave

These 3 test cases are performed on 3 different kinds of grids:

• structured
• triangular
• voronoi

Hey @Manangka , this looks really nice! One quick thing: have you checked the layout of the figures in the resulting PDF? When I download the artifact, the figures in there appear to be running off the page...

I have reviewed the new chapter (#62) in pdf form and sent a markup with comments to @Manangka

Hi @Manangka (CC @wpbonelli @aprovost-usgs ) , we discussed with the team today that it would be advisable to delay this until after the upcoming maintenance release where we will likely cherry pick around utvd and other ongoing/recent developments. Could you please hold off merging for a bit?

Hi @Manangka (CC @wpbonelli) , we discussed with the team today that it would be advisable to delay this until after the upcoming maintenance release where we will mask utvd and other ongoing/recent developments. Could you please hold off merging for a bit?

Will do
