FIX: Allow Object3d to be used in create_current_source_from_objects

[SMoraisAnsys]

Description

Previously the method create_current_source_from_objects was failing when one passed a Object3d as source or target because the checking of the existence of this object was only performed for int and str. However, the method should be working with input of type Object3d as described in the docstring (and because it makes sense tbh).
