Explanation

Mold material

Specifies the mold material in contact with the selected model feature.

The available options are:

Use global setting in advanced options: Select this option if you do not want to specify a local mold material in contact with this model feature.
Select a different top mold material: Select this option if you want to specify a local mold material, different to the mold material specified in the advanced options, in contact with the top side of this model feature
Select a different bottom mold material: Select this option if you want to specify a local mold material, different to the mold material specified in the advanced options, in contact with the bottom side of this model feature.
Select different top and bottom mold materials: Select this option if you want to specify a local mold material, different to the mold material specified in the advanced options, in contact with the top and bottom side of this model feature.

Note:

The top and bottom side of a Midplane element corresponds to the blue and red faces respectively in the Mesh Orientation diagnostic display.
Selecting a different mold material is a simple way to model the interface between the part and a mold insert, but you will get more accurate heat transfer results by modeling the insert as a separate volume.
