watr -> air Answered


i want to see the acoustic pressure movement for simple PZT 2D DISC (tx/rx) like this example


but if i change water to air i can't see the movement of acoustic pressure but i can get the rx output. picture upside is one moment when device is in air and picture downside is when device is in water. what i want to know is that why i can't see the acoustic pressure moving by just changing the material water to air?

Thank you for your help

  • It is likely that the acoustic pressure is very small. Compared to what is in your transducer, the range of variation in air is very small so the intensity plot contrast will appear as if it only shows the large changes. Try changing the range of values over which the colour changes.

    Review the command reference for the grph plot command and the rang option.
