i am analysing the vibrational aspects of fluid in a tank..how do i put the model BC..i have a fluid in a tank...and i want to perform the vibrational analysis of the whole systemm..to obtain the natural frequnecy response of the fluid inside it..since there is a lag of vibration due to inetrnal damping of the fluid, the fluid will vibrate at a different phase angle comapred to teh solid body..i have doen the experiments but want to use the theoritical modellcan anyone help..?
