hi In my research, the pressure acoustic field and magnetic field have been coupled with the fluid field. The pressure acoustic field and magnetic field are computed in the frequency domain. The frequency of acoustic field is 20KHz, while, the magnetic field is 20Hz. In my trail, I put this two step in the same study, the acoustic field was calculated in the first step, the magnetic field is the second step. Then the time-average force of this two process was added to the fluid field for the steady solution for the third step. However, i found that the acoustic driving force is much higher than what i individually calculted the acoustic field. then i set the frequency of accoustic field with 20Hz which is consistent with the magnetic field. i have got the same result as i have originally calculated. Thus the question is how could i avoid the the disturb of the frequency between acoustic field and magnetic field? i am looking for your reply. yours sincerely
