When a CAD part is analyzed in CAE, in earlier stages of design, it is simplified. Irrelevant features like, small-fillets/holes/chamfers are removed. Thin portions are idealized to midsurface etc. Such simplified model, takes lesser times/resources in CAE analysis, without harming accuracy of results.

So there are two aspects where TRIZ can potentially come in,

- techniques to remove small-irrelevant things while keeping principal shape

- techniques for dimension reduction

I've done a research on design optimization using CATIA Vs. TRIZ in weight reduction strategy for automotive components.

Please have a look on my list of papers. I'm willing to do my best to help you.

Good luck!

Thanks for the answers, I will soon have a look at the suggested papers
