Select the nodes on the model where you want to set the load(s), and enter the force to be applied (Nodal force) in the X, Y, and Z directions.
Select Apply. The load should now be applied to the model.
Click Close to close the dialog.
Tip: You can apply the load in any arbitrary (non-global) direction by first setting up a local axis system at the node (see Step 2). If a local axis system is not specified, the load will be set globally.
