Body rested on rigid plane
Altair EmployeeIf there are tires which are rested on the ground. To simulate this, I was thinking of considering ground as a rigid plane over which wheels are placed. What type of connection should be considered for line contact between tires and ground? Wheather a tie contact can be considered?

Altair EmployeeHI,
I think, to start with use RIGID wall with the tire which defines contact between the rigid and tire.
Yeah, as Ivan said, type 2 contact is not suitable.
Hi dragon,
tires in contact with the ground under gravity would result in a contact patch over an area.
There are two approaches to model such behaviour:
1. infinite rigid wal (Analysis>>Rigid walls)
2. Type 7 – ( General Purpose Interface )
a. Multi-usage impact interface, modeling contact between a master surface and a group of slave nodes.
b. General purpose interface and can simulate all types of impact between a set of nodes and a master surface.
A tied contact Type 2 – ( Tied Interface ) would not model the contact the most accurately.
a. Tied Contacts define an interface that kinematically connects a set of slave nodes to a master surface.
b. This interface is used mainly for the connections.
c. It can be used to connect coarse and fine meshes, model spot-welds, rivets, etc
