Error ISAT

coalgas · October 16, 2012, 03:51

Does anybody came across following error;

"Primitive Error on Node 1 : ISAT Cannot be used with two different gas-phase mechanisms"

I am trying reacting flow problem with parallel processors, with "Finite rate/eddy dissipation". There is two reaction mechanisms are involved a gas-phase and gas-solid. Anyone has come across this problem? Same case when executed on Fluent 13.0 works fine, but this error seems to be persisted on Fluent 14.0.

Any suggestion will be appreciated.

Hi chétan,

Did you find the fix for your problem ?
I tried to use 'Direct Integration' instead of 'ISAT' using the 'Integration Parameters' dialog box, but the problem persists.

Plz help if you have any idea about how to overcome this problem.
