Interface heat flux (3D Overmolding) result

The Interface heat flux result shows the amount of heat flowing from the current part into the previous part (i.e., from overmolding into original molding, or into a part insert). Negative values indicate heat flowing into the current molding.

This result is generated at the end of a Fill analysis using the Coupled 3D Flow solver.

Using this result

Only mesh faces which form the boundary between the current part and the previous part (or insert) are shown in this result. Blank areas indicate where the solver could not match mesh faces on one or the other part, and may indicate holes in the mesh interface.

Note: This result should not be relied upon to detect holes in interface meshing.

This result indicates how much heat is flowing between parts during insert or overmolding processes. Heat flow that is too high may cause remelting in the first part or insert. Heat flow that is uneven may cause stresses or warping in the first part.

Things to look for

Use this result in conjunction with the re-melt temperature result to check for areas which may have re-melted as a result of heat flow.

Use this result to check for possible warping in the previous part or insert.
