Hello Alialemana,
I couldn't able to figure out your problem exactly..I just can understand that your problem is not converging...
Could you mind sharing your model, preprocessing settings to check it thoroughly...
Also try the following, since there are two inlets, first allow flow from one inlet - converge the solution and then permit the flow from second inlet. If not then, reduce the URF values marginally to check it..

Best Regards

Dear Kummi,

Thank you for your reply. I am not able to understand where to patch the rate equation udf inside the porous media section. Can you please help me?

Thanks

Thank you for your reply. I have the following reaction:

ArS(l) + H2(g) = Ar(l) + H2S(g)

1. Do I need to define both reactants and products in the species list?
2. How do I segregate between the liquid and gas. Because if I enable mixture template in the species transport model for both gas and liquid then both phases will have all the species components but I need the gas phase to contain only gas species and liquid phase to have only liquid species.

I would really be grateful if someone could kindly help me.

Thanks

Hi, just to clarify...

I'm simulating the dispersion of cough particles in a mechanically ventilated room using DPM. if i neglect evaporation of the discrete phase, I do not need to enable the species transport right? Is multiphase model required in this case?

Thank you in advance.
