Hello Everyone,

It's about my graduate thesis, I ve been trying to make an analysis which is NDT. There is a specimen, transducer, and cylinder( for showing to cracks-voids)

I can't send a sound from transducer to specimen. That's why I can't see the result as a [db] and [f]

I'm so pleased whether anyone help me

thanks
