Input Parameters#

snes - the SNESPATCH solver
ctype - the PCPatchConstructType selecting the patch construction strategy

ctx - optional application context passed to func

Calling sequence of `func`#

pc - the PC associated with the SNESPATCH solver
npatch - number of patches
patches - the IS that define each patch
patchIterationSet - how the patches are iterated over
