chrono::ChLoaderNodeXYZ Class Reference
Description
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 ChLoadNodeXYZForceAbs.
