hello,
Some problem drives me crazy. i tried to solve oscillating plate of speaker.(transient) Can i impose normal velocity(not tangential) on stationary wall boundary? if not, please allow me to know which method is appropriate i already used 'morper' but the magnitude of displacement is too high relative to mesh size, so after several iteration/time step my solver diverged, generating negative volume mesh. my 2D, axisymmeric model is attached. and oscillation velocity is bellow, x-direction : 0.01*2*3.14159/0.01*cos(2*3.14159/0.01*time) [m/s] Any help can save my life. thank you |
