I often need to have forces applied to components that are based on more than one independent variable. What I do in these cases is to apply a force to a fixed object, knowing that it will have no effect. I then attach a results plot to that force. I can then use the results plot in an equation for another force.

What I would rather do is to have an equation space in which such complex equations and tables can be placed. Creating false forces and having transitional variables just to do this is confusing, inefficient, and could potentially slow the simulation.

Thanks in advance...

so you are using the forces like variables?

and you don't need to know how to create the expressions:
