There's no way to create a function ahead of time that will automatically update the forces during solution.  The only way to do what you describe is a brute force method.  The duration of the analysis is broken up into many short time steps.  A commands object is executed at the beginning of each time step which interrogates the previous solution and updates the force values with APDL commands.
