Detailed Description

Vertex model to represent a multi-stream Divider (i.e. a tee or multi-way valve).

Has one inlet, and two or more outlets.

Assumes outSplit[0] .. outSplit[nOutlets.val()-2] are fixed, thus they can be set:

Q("Spl.outSplit[0]")->set(0.25);

and they can be assigned:

MAKEASSIGNMENT(*Q("Spl.outSplit[0]"), One - splitPar, "Gas to RXX");

While outSplit[nOutlets.val()-1] is calculated and can neither be set nor be assigned.

The split only affects the total flow and does not change stream compositions

Options:

nOutlets Number of streams connected at outlet, valid range 0..INT_MAX, defaults to 2

List of ports:

in inlet to Divider
out1, out2, ... outlet of each stream from Divider

#include <libpf/Divider.h>

Remarks

Warning: Thread safe:; Extendable:; Platform dependencies:
