I am simulating sound propagation in mild steel.
frequency=5MHz mesh size=0.5mm
time incriment of wave amplitude=1e-9
instead of giving force at a node i have given boundry displacement
instead of showing sound propagation, my entire specimen(mild steel with 15 mm thickness) deflecting like a wave.I would like to know 1)what is the reason for that deflection?
2)what may be the possible solution?
