During the plausibility check, I receive the error message saying that the surface opposite to the contact surface cannot be localized. How can I fix it?

Answer

When modeling a contact solid, it must be noted, among other things, that the two contact surfaces must be arranged in parallel and designed identically.

In Figure 1, a contact solid with existing contact between the top and bottom surface should be created. The top contact surface is divided into two surfaces F2 and F3 and thus does not correspond to the bottom contact surface F1. Therefore, the error message shown in Figure 2 is displayed. It is necessary to define two contact volumes in this case. The contact solids can be created, for example, by the function "Create Solid with Contact." To do this, select the contact surfaces and open the corresponding function in the shortcut menu; alternatively, it is possible to create the contact solid manually. Watch the FAQ explanatory video to see both procedures.
