Creo includes simulation tools so engineers can test how models might respond to various physical loads and forces.  While simulation capabilities can be invaluable, they tax computer CPUs and cost time.  For every change to the model, you have to run a simulation study and wait for your computer to churn out the results. It might work pretty fast, but multiply that by all the different iterations you could go through, and the seconds and minutes adds up.  Creo Simulation Live will allow you to make changes in the model and view the results instantaneously – no more waiting!
