Error with Chemsep Property Package and Heater/Cooler unit

Postby Stephan » 26 January 2021, 13:50

I use COCO/Cofe in combination with a Chemsep property package.
when connecting a heater/cooler unit with a material stream
I get the following error message:

error: calculate failed for unit HeaterCooler_759: CalcEquilibrium failed: Invalid mass balance after equilibrium calculation

Is this a bug or might there be an erroneous model specification?

The files are in the appendix.

There is an issue with the PH flash in ChemSepCOPP in your example - it does not produce the right output. It is being looked into.

How long will it approximately take for a software update?

The issue is being worked on. I have no further information than that.
