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

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? |
