The remote force is not important. It was simply used to demonstrate the use of the equation load profile. It can be done with a regular force also. I have updated my project with another example.
The remote displacement is required at the support so that no stiffness as added (equivalent to pin joint).
However, using a load profile like this, in a linear static simulation, has no real value because you cannot learn anything more from 60 load steps than you can from one. The resulting stress is always linearly proportional to the load. So I am sharing this simulation to help convey the concept, you will need to adapt this to your own (presumably non-linear) application to get the results you need.
