I want to analyse the free vibration of a piezoelectric patch at open and short circuited condition in ANSYS. Do you know how to implement short circuit and open circuit B.C on a piezoelectric patch in ANSYS?
any comment yet?!!!!
What are the advantages and disadvantages of analytical and semi-analytical methods over numerical methods like FEM and FDM? I am looking for detailed advantages and disadvantages.
