Wall superheat bisection algorithm failed to converge
 
Dear all,
I met a problem when I try to simulate a subcooled boiling case with RPI model

When I run a steady state calculation of subcoold boiling flow in a central heated tube, the calculation is all right.


When I change it to an unsteady case, I got this error message:

Wall superheat bisection algorithm failed to converge. Continue with wall superheat = 1.0000072E-01 of minimum relative error = 4.5705986E-2

Is there anyone can offer some help?

Thanks

Zhang Peng
