By using fusion mesh, the deflection due to Corner effect can be isolated from total deflection when running wapage analysis, but with 3d mesh model to run wapage, there is no this option of Corner effect.
The question is if running warpage with 3d mesh model already consider the corner effect?
And which mesh model would be better to use for running warpage when we encounter the particular part with long side wall?
Best wishes
Thanks

The corner effect is caused by differences between shrinkages in the in-plane and thickness direction on curved or angled parts.
2.5 D solvers treat the thickness direction differently over the in-plane so they need a special handler for the corner effect. In 3D the corner effect is obtained naturaly.
The question about the best analysis between 3D and 2.5 D is a complicated one, that is why Moldflow provides both options:
Hello,
when you said "In 3D the corner effect is obtained naturally." what do you mean with "naturally"?
if I am using a 3D mesh, are the corner effects included in the results? I have not to indicate to solver to calculate it, is it correct?
Thanks and regards
Hi Vherna,
Yes this is correct. The corner effect is caused by thickness shrinkage been different from the in-plane shrinkage. In 2.5D simulation it requires separate calculations, in true 3D it is obtained automatically so far as the shrinkages are right.
