Strange result in flow front temperature

Hallo
The result of the flow front temperature in a dual-domain analysis (suggested by mold flow) is often not real. I am attaching an image of a part where we see that there is no difference in temperature of the flow front, and this is not real. The result is true if  I make a 3D analysis. Why? If the part is Dual Domain.
The material used for the analysis is ABS.

Regards
Giampietro

Hi,
without having the Dual Domain model, it is diffcult to find the reason.

 

Some suggestions:
A reason for the Dual Domain model could be that an area is identified thin, thin and filled early, and temperature drops quickly/more than expected.

To evalute this result, use result scaling (Right-click the temperature result: Properties: tab Scaling):
- for example: first look at temperature between 255 to 263C : to see it looks as expected
- then look at temperature between 89 to 100C (increase upper limit if needed)
- set result properties, tab Part Display : Edge display off // Surface display: Transparent
This helps to identify area with the low temperature, and to see what model looks like in that area.

 

You can also run Design Adviser to analyze the Nominal wall thickness

(The new Design Adviser in Autodesk Moldflow Adviser 2011 replaces the Geometry Adviser available in previous releases with a broader range of tools for part design validation.)
