How to: Optimize Simulations with Direct Modeling

Simulations can help you quickly find weaknesses in your designs as you work—long before analysis or prototype building. But what happens next? That is, how easily can you modify the model once you discover its flaws? And then run another simulation?

 If you use Creo Simulate and Creo Flexible Modeling Extension (FMX), now you can simulate and optimize your design all in one place. Here’s how the new integration, introduced in Creo 4, with Creo Simulate and Creo FMX works:

The highlighted hole can be removed while in Creo Simulate.

Remove a Feature Within Creo Simulate

To remove a feature within Creo Simulate:

  1. Using Creo FMX, highlight the feature you’ll remove.
  2. On the Refine Model ribbon bar, click Remove.
  3. Preview and/or Accept the change.

 It’s important to note that currently the change is only applied in Creo Simulate. You must promote changes made in Creo Simulate to apply them to the parametric model. To promote a change:

  1. In the Model Tree, expand Simulation Features.
  2. Right-click the removed feature and select Promote.

 The system applies the change to the parametric model.
