      One would need to make the derived parameter to:
      1. have all the same units
      2. dimensionless
      or
      3. numerical value
      which means one need to include units in your expression. Let’s say P3 is a Reaction Force in N and we wanted to take the square root of P3, and drive another input Paramter with this value. Simply entering “sqrt(P3)” gives an error. One then need to include the units sqrt(P3*1 [N])
