Virtual contact is appropriate when the contacted part is rigid or has negligible deformation compared with the part that you are simulating. Using virtual contact gives more realistic results than a clamp restraint and is easier to set up than surface-based contact. When you define virtual contact for part of your model, the app automatically creates a mesh conforming to the shape of the selected faces. This mesh acts as a contact surface for those faces. The contact interaction is also created automatically. The created surface acts as a rigid body whose motion is controlled by a single point. You should constrain the motion of the point before simulation to ensure that you have a well-constrained model. Virtual contact interactions support all loads and constraint types supported by rigid bodies. | |||||||||
