Q: Why is there a slider that can add or remove material after optimizing when the result should be optimal?

A:  Calculation results will always be predictions. Material is not needed everywhere, but the concept will certainly contain 'grey' areas, where, for example, 50% material is required. Use the slider to make those elements 100% or 0% depending on your design priority: weight or strength.


Q: What is meant by the Safety Factor in Inspire?

A:  The yield strength of the chosen material will be divided by this factor to be on the safe side of the calculation.


Q: Can Altair Inspire also compute non-linear behavior?

A:  Yes. No. Non-linear means that the system or material behavior changes over time. Inspire can calculate this for sliding contacts, where objects eventually come loose (and therefore the system has changed). But Inspire is not able to calculate non-linear material behavior. Take a look at HyperMesh for this.


Q: When I run my simulation, why does the result fail to respect the safety factor, while there is still enough material to add using the slider in the results window?

A: You probably opted for an optimization for Maximize Stiffness and entered a % target material. Inspire initially wants to use all available material, but must meet your wishes. Therefore, you should use Analysis to check the result and possibly iterate a few times.
