Warpage

[prabu27]

dear all.

                    i have done one 3d meshing and one dual domin mesh for the same part ..an ran Fill+pack+warp for the same part . but results is different warpage is high in dual domin model and fill time also double in dual domin model.. i want to which one is correct ? how to choose the mesh type..

part geometry is simple handle shape. injection location is one side of the handle..

please anyone clarify me

I guess this question does not have any satisfied answer, as solvers are different results will be different.

But you can take precausions, whenever meshing for DD/Fusion check whether mesh match % > 90 & use 3D when thickness

of part is over 4-5mm.

I can recall "Maybe Moldflow does not work properly, but the real world neither" PascalGosset is saying always.

hi,

         you are correct here the match percentage is 42% only,

but our problem is this is the very simple geometry i can't increase the match % more than this.i tried..

then what will do?

In that case you need to go for 3D always.
