Error cfx #001100279
 
e need help for this problem below:

-------------------------------------------------+
| ****** Notice ****** |
| Newtons method failed to converge in 100 iterations. This |
| occurred while computing the following variable: |
| |
| Variable Name : Temperature |
| Location Name : serpentina |
| Mesh location : VERTICES |
| Mesh entity : |
| Last 3 Changes : 3.08842E+23 3.76202E+23 4.58254E+23 |
| Tolerance : 1.0000E-02 |
| |
| The Newton iteration was diverging. The solver will continue |
| with the variable field as it was on the final iteration. If |
| this situation continues you might try decreasing the Newton |
| iteration under relaxation factor. This can be changed by |
| setting one of the following parameters: |
| |
| Temperature : "Constitutive Relation Under Relaxation" |
| Pressure : "Newton Pressure Under Relaxation" |
| |
| for your mixture using the definition file editor. |

The floating point overflow is a FAQ: http://www.cfd-online.com/Wiki/Ansys...do_about_it.3F

But to get it like this you probably have some strange material properties. Can you explain what you are doing?
