Coal devolatilisation - two competing reactions
 

Dear all,

I am looking for advice in describing devolatilisation of coal in CFX using two competing reactions. I have been told that the reactions need to be specified in a CEL code. Does anyone have a code example that shows how to set this up? Any other hints regarding this?

Best regards,
Reine

Update
 

I have defined two reactions - Devolatilization RC1 and Devolatilization RC2 - and included them in the Multiphase Reactions List. I get the following message by the solver when running the simulation:

Parallel run: Received message from slave

Has anyone seen a similar solver message?
Do you have any recommendations how to setup the simulation correctly in order for both reactions to be used?
