Two step analyzes

Hi
I would like to perform two step analyzes: first I want to add a gravity load to my model, and after gravity loading add a force acting for a part of my model. How to setup a proper load step?
I want to see the results with only gravity loading and then by force. Then use a superposition method to calculate the stress resulting purely from the force.
This is a linear static analyzes without contact.
Best regards!

    This can be achieved in three loadstep.

    For gravity load use GRAV card and define first loadstep.

    For force load you can define second loadstep.

    To view the combined effect of gravity and force use LOAD/LOADADD card and define third loadstep for combined effect.
