problem while transferring from 32bit to 64 bit
 
I have successfully finished a simulation with cfx11.0 32bit(converged).

however, when I read in 64bit cfx11.0, and start calculation, the iterations terminated after 5 to 6 steps. and the error information are:

ERROR #004100025 has occurred in subroutine SCL_RESCH. |
| Message: |
| A floating point overflow has occurred. Check solver |
| parameters, boundary conditions and mesh quality. The |
| calculation will be terminated. |
| Note: if this error occurs at the first iteration, that may |
| be caused by the initial guess, e.g., a zero initial |
| velocity and zero dynamic viscosity. |

I seem to be having the very same problems?

Did you ever get to the bottom of this?

Thanks.

sorry, not yet, but you may reinstall cfx11.0 and try again
