Webcast Q&A

Question from Anand:  Is there any consideration for fatigue safety factors as each design shape may have different fatigue resistance?

Answer:  You could take the final model and run fatigue on it.

Question from Anonymous:  Can an optimal geometry be created with thermal conditions?

Answer:  Soon.  Right now, it is only Structure.  We will soon have Modal and Thermal.

Question form Anthony:  If a material(s) are not listed in library, can we include our own material along with its properties?

Answer:  Sure, you can add and edit materials.

Question from Ryan:  If we constrain the build volume, why have an exclusion body?

Answer:  An exclusion is a keep out from within the preserved body.

Webcast Q&A

Question from Mike:  Please explain the different types of contact.  Can you do a frictional contact element?

Answer:  The contact is simply transferring load between components/parts.

Question from Mike:  You had mentioned that other tools use FEA and Creo gen design does not?

Answer:  The FEA approach starts with a large model and removes material where there is no strain.  This builds the model generatively within the open space and analyzes that.

Question from Juan:  Can we calculate the security factor?

Answer:  Yes, using the cloud options, the tool will build many models and you can filter based on factor of safety.

Webcast Q&A

Question from Kevin:  Does it create geometry from a datum reference frame?  Or would you have to re-create the model using that methodology?

Answer:  The Solid geometry could be built as part of the existing model or from a new part (with start part datums, etc.)

Webcast Q&A

Question from Dakota:  Could you make the exclude part of the envelope?  Why does it need to be a different feature?

Answer:  You could.  But this gives you the flexibility to build multiple models some with and some without the exclude portions.

Webcast Q&A

Question from Kurosh:  Does the design try to limit hot spots in stress?  I missed that in the design criteria (prioritize deformation over stress).

Answer:  It does try to distribute the strain as much as it can.

In Creo 9.0, we added Modal optimization. 

We are targeting Creo 10 for Thermal (subject to change).

[lwestbrook]

In Creo 9.0, we've made this easier by adding a new Structural optimization goal: minimize mass at a target safety factor.
