Reaction simulation in Fluent

Do I need to use UDF (user-defined function) if I have 2 different reactions taking place in different zones in my model. [In my model there is a tube through the center of a Furnace in which combustion occurs. A different reaction takes place inside the tube which uses the heat released by combustion in the furnace]. So, will I need to define a UDF for the reaction in the tube or Fluent allows doing this without using a UDF ?
Someone plz help. |

Hi Ernesto,
When I try to run my simulation with 2 different reaction (mechanism) in different regions, I get the following error, "ISAT cannot be used with two different gas phase mechanisms" . Do you have any idea about how to overcome this problem ? I tried to use 'Direct Integration' instead of 'ISAT' using the 'Integration Parameters' dialog box, but the problem persists. Plz help. |
