Uncorrected mapping with NCmesh about remhos

[vladotomov]

Hi @sungho91 the methods -lo 3 and -lo 4 are not implemented for NC meshes and won't work.

We haven't tested Remhos with NC meshes, but I expect some combinations to work. I'll try and let you know soon.

You can also try by simplifying the setup (disable the monotonicity), and then go back incrementally. For example -ho 3 -lo 0 -fct 0 and if that works, try enabling some -lo option, and then finally try enabling the -fct option.

According to my quick couple of tests, introducing a low-order solver prohibits advection between coarse- and fine-mesh regions. -ho 2 or -ho 3 without -lo and -fct works but the solution from them seems to need improvement.

I'm on travel this week, but I'll take a look when I come back.

@sungho91 seems that the -ho 3 and -lo 5 (simplest LO solver) work with the code in master, I tried these:
mpirun -np 4 remhos -m ./data/amr-quad.mesh -p 14 -rs 2 -dt 0.001 -tf 0.4 -ho 3 -lo 5 -fct 2
mpirun -np 4 remhos -m ./data/amr-quad.mesh -p 14 -rs 2 -dt 0.001 -tf 0.4 -ho 3 -lo 5 -fct 4
