Attempting high pressure combustion for oxygen and kerosene with non premixed pdf(chemical equilibrium) model and density modeled with SRK(real gas model). Facing convergence difficulties in PBC solver. Case started at low Courant No. and low URFs, but gave trouble after some iterations. Pseudo transient solver also showed divergent trend for residuals. Suggest strategy for starting this case or inform about any specific requirements for modelling such case.

Hi, how can i enable the real gas model with the non premixed pdf equilibrium model?
