Enumeration Type Documentation

ConvStatus

enum SIM::ConvStatus

Enum defining the various convergence statuses that may occur.

Note

The order of the values are not random. It reflects the severity of the status somehow (the smaller the value, the further from convergence).

Formulation

enum SIM::Formulation

Enum defining various solution formulations that may occur.

Used as a bit field - power of two values only.
