The top problems I help my clients solve are (1) getting to a better understanding of underlying physics (2) reduction of variability (3) improvement of reliability.

The Beast In the Dungeon

The application of FEA to ultrasonic devices can solve all three of these problems. However, there is a beast at the bottom of the dungeon if you choose to utilize this tool. That beast is “matching FEA and experiments.”

You say there is no beast? Really?

It’s all too easy to just take a few steps into the dungeon and say “There is no beast, all I saw were little bats.” You say “Matching FEA with ultrasonic devices is not tough.”

I challenge you - I say you did not go far enough down into the dungeon. How do I know that? I can just ask you three questions:

Three questions to know if you really went deep in the dungeon

(1)  How many different samples did you use for your experimental comparison?

(2)  Does your model include nonlinearity and how are those physics validated with experiments?

(3)  Does the model applied in different conditions still match experiments?

Some advice for you

You did not go far enough down to see the beast. Also, for the sake of your life I must tell you something. There is no prize for slaying the beast. The point of going into the dungeon is to save your friend Sir Done-Is-Better-Than-Perfect. The beast is a danger and a distraction, but not the prize.
