some trouble about CFX-solver

I met one problem about CFX-solver, the output file shows:
================================================== ====================
| Timestepping Information |
----------------------------------------------------------------------
| Timestep | RMS Courant Number | Max Courant Number |
+----------------------+----------------------+----------------------+
| 1.0000E-02 | 5.06 | 18.83 |
----------------------------------------------------------------------

+--------------------------------------------------------------------+
| ERROR #001100279 has occurred in subroutine ErrAction. |
| Message: |
| Floating point exception: Overflow |

| |

+--------------------------------------------------------------------+

+--------------------------------------------------------------------+
| ERROR #001100279 has occurred in subroutine ErrAction. |
| Message: |
| Stopped in routine FPX: C_FPX_HANDLER |

+--------------------------------------------------------------------+

+--------------------------------------------------------------------+
| An error has occurred in cfx5solve: |
| |
| The ANSYS CFX solver exited with return code 1. No results file |
| has been created. |
+--------------------------------------------------------------------+

Who could help me solve with this problem?
Many thanks in advance!

This is the most general error.
It means that the simulation is not set up properly, probably Boundary conditions or it might be something else.
Without providing any details, only God can help you.
