ERROR #004100018; Fatal overflow in linear solver

March 17, 2006, 07:11

Hi everybody,

I want to simulate a easy geometry (straight tube) within the super critical region of pressure ang temperature. That is why I have to provide the material properties of the water in function the temperature to CFX Pre. I fitted the mat. prop. curves with 4th order polinomes, but when I lunched the solver, then It stopped with the following error:

ERROR #004100018 has occurred in subroutine FINMES.| |Message:| | Fatal overflow in linear solver.

Can you help me to resolve this problem?

Thanks in advence!

Attila

Your solution has diverged............try reducing the time step.
