Defining the domain
All simulations, whether using an embedded boundary (EB) or not, are specified on a simple cuboid domain. The
low and high corners of the cuboid are defined by the prob_lo and prob_hi inputs.
The following inputs are defined using the geometry prefix.

Attention
MFIX-Exa geometry restrictions:
There is no support for 1D or 2D simulation domains.
Cartesian is the only supported coordinate system.
