xorder=3c Valid for GR?

[smressle]

Hi all,

Is xorder=3c (ppm with characteristic projection) compatible with GR (or SR)? It does not seem like it should be but there are no warnings and the code runs fine and doesn't give nonsensical results.

In the reconstruction, it converts primitives to characteristic variables, interpolates them, then converts back to primitives. This conversion is currently non-relativistic only. As primitives in SR are similar to non-relativistic cases, it may run (and the results are not totally crazy), but I do not think the results are consistent. Probably we should add a trap there.

Thanks for clarifying! That's what I expected, but the results were surprisingly good, haha.
