There was a problem hiding this comment.
If we ever do a proper refactor of ingrid, we can probably have each topology state which patches to delete. Could help keep things tidy and trickle in future changes

Description of changes
This PR adds an up_down_symmetry option to INGRID. This enables grids to be generated which are symmetric about the midplane, and can be used with the
com.isudsymoption in UEDGE.As an example, we start with this UDN configuration:
Changing the INGRID input file settings from
to
allows INGRID to generate a half-domain configuration, with ghost cells added to the upper patches where they meet the midplane:
A key part of this process is an added module to INGRID,
udsym_tools.py, which takes the magnetic equilibrium, chops off the upper half of the domain and extends psi from the lower half by matching field lines on the outer/inner side.Important note: when using this option, the INGRID input file should be configured as if the equilibrium contained just a single divertor. So for a UDN geometry, the upper x-point should be ignored and the INGRID input file should specify one x-point, i.e.
How was this tested?
Locally on some example files.
