3D Disk

3D Disk: Currently broken (initialized incorrectly)

This models the Milky Way's stellar disk. Gamma is set to 1.666666667. Full initial conditions can be found in cholla/src/model/disk_ICs.cppunder Disk_3D() (Which has ICs for several different profiles hard coded in...). This test is performed with the disk build (cholla/builds/make.type.disk).

Upon completion, you should obtain 501 output files. Currently this test is producing a grid of zero density, zero energy, and undefined pressure for the entirety of the run.

Note that the 2D disk, which does run, has its initial conditions set in cholla/src/grid/initial_conditions.cpp.
