During the plausibility check, I get an error message saying that the surface opposite from the contact surface cannot be located. How can I solve this?


When modeling a contact solid, it is necessary to pay attention to the parallel arrangement of both contact surfaces and the identical design, among other things.

In Figure 01, a contact solid with the contact between the top and bottom surface should be created. The top contact surface is divided into two surfaces S2 and S3, and thus does not correspond to the bottom contact surface S1. Therefore, the error message shown in Figure 02 appears. In this case, it is necessary to define two contact solids. The contact solids can be created, for example, by using the "Create Solid with Contact" feature. To do this, select the contact surfaces and open the corresponding function in the shortcut menu; as an alternative, it is possible to create the contact solid manually. Watch the FAQ explanatory video to see both procedures.
