Dear,

Have a strange problem after a few days of PDF combustion simulation I found that Fluent is not changing fluid thermo. properties like mixture viscosity or thr. conduction and all appears constant( properties display mol. viscosity). I used polynomial for all fluid properties and for sure all is ok in the material panel. My question is could you check in your Pdf cases that Fluent is using mixture properties applied by you?.

At this moment I'm using average mix. properties for the viscosity and thermal cond. but it is not right.
