Creo Simulate provides the capabilities necessary for structural and thermal simulation analysis. It gives users that all-important early insight into how their product will perform. It can also reduce the time and cost associated with physical prototying.
HOW DOES CREO SIMULATE WORK?
Creo Simulate allows you to open and view CAD data from other Creo apps, so that you can begin your analysis. After you have opened the model you want to analyse, the first step is to define the material properties by selecting it from the library and applying it to the model. The next step is then to add constraints to the model, where you define how this part is fixed under a load.
