Nodes of different colours represent the following:
Solid arrows point from a procedure to one which it calls. Dashed arrows point from an interface to procedures which implement that interface. This could include the module procedures in a generic interface or the implementation in a submodule of an interface in a parent module. Where possible, edges connecting nodes are given different colours to make them easier to distinguish in large graphs.
FUNCTION HWBaseboardUAResidual(UA, Par) RESULT (Residuum)
! FUNCTION INFORMATION:
! AUTHOR Fred Buhl
! DATE WRITTEN February 2002
! MODIFIED
! RE-ENGINEERED
! PURPOSE OF THIS FUNCTION:
! Calculates residual function (Design Coil Load - Coil Heating Output) / Design Coil Load.
! Coil Heating Output depends on the UA which is being varied to zero the residual.
! METHODOLOGY EMPLOYED:
! Puts UA into the baseboard data structure, calls SimHWConvective, and calculates
! the residual as defined above.
