chrono::ChLoaderXYZnode Class Reference


Loader for a constant force applied at a XYZ node.

An alternative is to set directly the node's own force member data as mynode->SetForce(), but this approach is more flexible (e.g. you can apply multiple forces at a single node). Another option is to use ChLoadXYZnodeForceAbsolute.
