New 2d test problems for hydro and MHD in 2D

#305 Merged at 2fe9203
  1. Tom Abel
  • Added initial conditions and parameter file for the problem studied by Lecoanet et al (2015)
    It also works in parallel.

  • Make it work with AMR and RefineAtStart in parallel.

  • Added AMR parameter file.
    This uses basic slope refinement on colur field only.
    This is not the best strategy, os is just useful
    to test that RefineAtStart and AMR is workin in general.

  • Correct bugs in Colourfield advection for HydroMethod=3 which were already
    correct in HydroMethod=4.

This test has now been tested with HydroMethod 0, 3, 4.

    Would it be possible to put the 2D-LongKH-AMR.enzo into its own directory? There's a general one-to-one between tests and directories, I'm going to totally forget about this one where it is.

    I ran the test, and I think I did something wrong, so maybe usage could be explained. I ran 2D-LongKH.enzo on 8 cores, with changeset 9ec0bc7176a6. I do
    and I get this
    and for snapshot 18, I get this:
    neither of which look like what I expect from the linked paper. Did I mess up? If so, could you clarify? Or are my expectations that it should look like one of the figures from the paper off?

      Ah, ok. That looks more reasonable. It doesn't look like it gets as chaotic as in the paper, is that a parameter space issue? It just kind of looks like a wind-up. Here's what I get:

      Its a useful starting place for people who want to do that test and looks good. I'll approve it.

        Yes they did much higher resolution in the paper, but I wanted to run fast for testing and so stuck with lower resolutions default parameters. It does work in parallel however...

    This looks good to me. I compiled and did a few quick runs with various parameters to make sure it ran, but didn't have the patience to see it through to useful output. I'm approving but a merge should wait until Dave confirms the run produces correct output on his machine...
