nIn Fluent interface, Kerosene Volume Fraction is seen as the first screenshot but once the calculation process is done via System Coupling, CFD Post says that Kerosene Volume Fraction is 0 (As seen from the third screenshot) at all fluid domain which is meaningless because defined and initialized it from Fluent before I run the simulation.nnThank you for your help. I will take a look at that discussion and let you know if I've reached the solution or not.Thank you both for your help.nn
