Dear all Friend
I have a problem with a subcooled boiling model. I'm looking for some help from people who are familiar with the RPI Wall boiling model in CFX
I am trying to model boiling in a straight heated tube. The problem is set up by steady,constant property material,both as continuous fluid,buoyant,Homogenous turbulence,mixtuer two phase model and RPI wall boiling model.
My problem is as following: Depending on the problem condition the calculation crashes after some number of iterations following a huge number repetitions of the following message:

" cal_TSUP1 WARNING: Changing upper bound for heat partition algorithm "

and at the end the error message is the following:

" ERROR #001100279 has occurred in subroutine ErrAction. Message: Heat partitioning algorithm failed to fix upper bound of bisection

Details of error:- ---------------- Error detected by routine FNDFIL CFNAME = * CRESLT = OLD
"

Can anybody help about this problem?
thanks to all
