279 Numerical Damping • It is now possible to input Numerical Damping within the range of values between zero and less than 4. • Example: Pendulum simulation with Numerical Damping of 3.99 and 0. < Numerical Damping 3.99 vs. 0 > -> It can be seen that the smaller the value, the more freely the movement is.
