Scale scenario

This calculation combines several streams and calculate the scale scenario at a series of locations of different conditions.

params	type	description
name	string	name of output stream
chemistryModel	string	chemistry model file (dbs) name for scale scenario calculations
externalStreams	array of objects	inputs for external streams
inletInputs	array of objects	flow rate specifications for mixer inlet streams
scenarios	array of objects	scale scenario specification

After combining all inlet streams, this calculation performs a series of calculations in the locations specified as below, where the outlet of each location is passed as the inlet to the next location.

The "result" contains all stream outputs for each external stream. Results of each location are listed as an array of objects in result.scenarioOutputs, with location and result of corresponding stream output.

by their names specified in the input.
