Select the nodes on the model where you want to set the load(s). Enter the force to be applied (Nodal force) and the allowed rotation (Nodal moment) for 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.
