I am studying coal gasifier numerical simulation.

But I have unstable solution of fluent result. keep iterating, result gradually

change and oscillating.

In my opinion, this cause from unstable k,e value of turbulent model because gasifier size is really small over coal feeding rate.

And also, changing of particle position cause unstable solution.

So, I want to keep particle position during DPM iteration, after fully iteration.

But I can find appropriate method to maintain particle.

Please help me~~~

Sorry for my poor English

Thanks
