Hi all,
I want to a fill analysis of a part in moldflow, i conducted the analysis using dual domain and 3D mesh without changing any input parameters. thee is difference in fill time about 0.22 sec difference, the part is very small 0.22 sec fill time difference is very valuable. now my questions are
1)Which one should i trust?
2)Why is there so much difference?
Can anyone please clarify my doubts....
Thanks in advance

you can trust 3D, As we do .Provided you are using the software the way in intended to be used.!!
"Simple parts with close to no variation in wall thickness" - Have those parts every day 300 x 400 x 2.3 mm in PMMA
I made the experience that the pressure results in DD are very far away from reality - 3D much better (matched for about 90%).
E.g. : DD: 130 MPa 3D: 95 MPa Real: 100 MPa
But you can't tell universal....extremely depends on geo and material.
If you need weld lines - never use DD.

Jay
