One of the great advantages of Creo Simulate is that it can help you optimize your models as you design in order to achieve a specified goal while respecting specified limits; for example, minimizing the mass of a part without compromising its strength.
Traditionally, you would adjust some variables (like a wall thickness), run an analysis, note the resulting stresses and deformations, then adjust the variables again, analyze again, and so on until you get the perfect result. Or you could let Creo Simulate find the ideal variables for you. Here’s how:
[Ed. New to Creo Simulate? Check out the introductory video below.]
Before you start optimizing a design, make sure you’ve already defined and successfully run a static analysis. This analysis will be used as the basis for the optimization study.
In setting up the Optimization Study, consider what Goal you are trying to achieve (for example, minimizing the total mass) and your Design Limits (for example, Von Mises Stress less than 525 N/mm2). You should also know which key dimensions (Variables) you want the system to iterate (for example, the thickness of a particular feature).
To set up Creo Simulate to find the optimal value of your Variables, follow these steps:
Optimization Study Definition dialog completed.
Before, mass of part is 6.19 kg.
After optimization, mass is 6.17 kg.
