General

The component 93 enables the creation of independent components with the help of EbsScript. Contrary to the normal EbsScripts, an EbsScript stored in the component 93 is called in each iteration step while solving the equation system.
Note:
There are characteristic lines, result arrays, specification matrices, and result matrices for these components, too.
It is possible to have result values calculated in each iteration step. See tab "Calculation" -> "Calculation options" -> "Result calculation" -> (1) "Calculate results at each iteration step"

There are additional interfaces for Component 93. See tab "Experts" and notes in chapter "Editing components" -> tab "Experts".

The specification value “FAUX“ controls if an additional auxiliary call is executed prior to the actual iteration step (”ksGetMode“ yields the value “PreIteration“ for this call). It can be used to call the following functions for controlling the max. residual terms of storage components:

• function ksGetGlobalMaxTimeInterval:Real; internal;
   // maximal global (model) operation-time in seconds

• procedure ksSetMaxTimeInterval( time:Real ); internal;
// set maximal local (component) operation-time in seconds

• function ksGetMaxTimeInterval:Real; internal;
   // maximal local (component) operation-time in seconds !!! reports the last value set by ksSetMaxTimeInterval

The specification value “FDEFEQN” allows switching off the generation of the default equations; this way, the mandatory call of ksRemoveAllEquations can be omitted
when setting equations.
For newly inserted components, the standard value is 0 “No automatic default equations“, for existing components the value is set to 1 ”Generate automatic default equations“.

Details for programming the EbsScript in this component are given in the chapter under EbsScript under KernelScripting. 

User Input Values  

 

FSEQ	Flag to define the position in calling sequence =0: Parallel to other components =1: Late, after fluids are recalculated
FDEFEQN	FLag to automatic default equations:  =0: No automatic default equations =1: Generate automatic default equations
FAUX	Flag to Auxiliary call between iteration steps:  =0: No auxiliary calls =1: Execute auxiliary call
FPROG	Program-ID (Classification of the component sub-type specified by the user)
SPEC1,..., SPEC40	Specification values that can be defined by the user (can also be used as nominal values) Note: Due to the expansion of the number of pins, changes may occur if there has been an iteration across all pins in the script and program respectively.

Physics Used

The physics used in this component is defined completely by the EbsScript stored by the user. In this EbsScript, the parameters mass flow rate, pressure and enthalpy can be set for all 9 output connection lines. 27 simple equations are used for the equations system, in which the values calculated in EbsScript are specified as constants for the corresponding parameters.
