◆ sequential()

int FallingFilm::sequential ( void )

overridevirtual

Returns: the maximum number of iterations for sequential computation defaults to 5; to increase it in complex flowsheets that contain sub-flowsheets, override this function; to decrease it for testing purposes, invoke setMinSequential in the constructor.

Reimplemented from FlowSheet.

◆ setup()

void FallingFilm::setup ( void )

overridevirtual

performs initializations required immediately before solution

Implements Model.

◆ type()

const std::string & FallingFilm::type ( void ) const

inlineoverridevirtual

Returns: the C++ name of the class the instance belongs to

Note: it is the responsibility of the caller to not access this reference after the lifecycle of the Item

Implements Item.
