yjs1027 is on a distinguished road
Im now research about radial turbine.

And using Fluent for CFD analysis.

I use MRF model under
Density Base
SST K-w.

and initial condition are below

inlet total pressure : 998430 pa
inlet total temperature : 358K
inlet mass flow rate : 0.402 kg/s

outlet total pressure : 166405 pa
outlet total temperature : 230K

So, i use pressure inlet and pressure outlet as B.C of this model.
Put inlet total pressure and temperature in pressure inlet,
and put outlet total pressure and temperature in pressure outlet.
Furthemore, i put 0 pa in operation pressure.

But in has not conversing.

What is problem of this model?

I have not enough time for submit my paper TT

Please help me.
