yes, my sought-after parameters are the maximum temperature and the surface coverage of pt(s). however they just keep changing. I think the case has not converged yet.

but like you said GRI 3.0...

there is no such warning during simulation.

yes, I tried to build a monitor to judge convergence. however, I did not know which parameter is appropriate. The mass balance is reached very early. I...

I think it's too slow. now after 4 days' iteration, the maximum temperature is still decreasing. some xy plots have a lot of discontinuities when I post-process the case.

I am wondering what is...

micro-channel combustion simulation

hello all,

I am doing a catalytic methane combustion simulation. The gas mechanism is GRI 3.0. the surface mechanism is Dutchman mechanism.

the reaction model is species transport with laminar...
