Regions definitions

Regions are used to define sections of the domain. They may be either boxes, planes or points. They are used in building initial condition regions.

	Description	Type	Default
mfix.regions	Names given to regions.	String	None
regions.[region].lo	Low corner of physical region (physical, not index space)	Reals	0 0 0
regions.[region].hi	High corner of physical region (physical, not index space)	Reals	0 0 0

Below is an example for specifying two regions.

mfix.regions  = full-domain   riser

regions.full-domain.lo = 0.0000  0.0000  0.0000
regions.full-domain.hi = 3.7584  0.2784  0.2784

regions.riser.lo       = 0.0000  0.0000  0.0000
regions.riser.hi       = 0.1000  0.2784  0.2784
