Hi all,
I am simulating a propane catalytic combustion with fluent. The golobal one-step gas phase and surface reaction rate are defined with DEFINE_VR_RATE and DEFINE_SR_RATE macros. I found an interesting thing that is when I use serial mode, then mixture can be ignited. However, when I use parallel model of fluent, mixture can not be ignited. Mixture temperature just drops all the way down to room temperature when iteration get started. I am wondering why would this happen? Do I need to parallelize my UDF code? Best regards Weiqiang |
