Geometry

Selection of an appropriate coordinate

Determine the domain size and shape

Any simplifications needed?

What kinds of shapes needed to be used to best resolve the geometry? (lines, circular, ovals, etc.)

For commercial code, geometry is usually created using commercial software (either separated from the commercial code itself, like Gambit, or combined together, like FlowLab)

For research code, commercial software (e.g. Gridgen) is used.
