Optimization Goals on two different surfaces

Umuteng · February 7, 2021, 14:36

Hello everyone,

This time my question is related to optimization goals.
Is it possible to obtain pressure on two different surfaces and assigning difference between these two surface pressures as an optimization goal?

Thanks.

It should be.
The objective is SURFACE_PRESSURE_DROP.
You set it up by listing outlet and inlet surfaces in MARKER_ANALYZE (in that order).
The type of average is set by MARKER_ANALYZE_AVERAGE (AREA or MASSFLUX).
It is hardcoded for static pressure which might not be ideal, you can hack it easily by changing CFlowOutput.cpp around line 546.
