Out-of-phase flap motion

Hello all,

I'm working with a rectangular box with a top and bottom mounted flaps. In x-z plane, I want these two flaps to move out-of-phase. I defined the phase angle for one of the flaps as pi but still they're not moving the way I want.

Does it have anything to do with the precision I'm using since I defined pi as 3.14159265359 but even if I define it as 3.142 it has almost no effect on the motion or am I missing something?

Thank you.


  • In Case_Def it says

    comment="Initial wave phase in function of PI (def=0)"

    So does it mean if I define phase as 1, it would be 1*PI?
  • The best way to know that... is to try and check the result...
    But the response is YES
  • I did try but didn't get what I was looking for. Turns out there was something wrong with the geometry.

    Thanks for the answer.
