HI Ming Li, if you can read on German i can send you one example with comments and a little abstract. But the best way (believe me) is to read the Help-file and log-in in the xANSYS-Mailing list (http://www.xansys.org/). Regards, Vitali Emelianov -----Ursprüngliche Nachricht----- Von: Li Ming Betreff: [mems-talk] piezoelectric material using Ansys I am studying dynamics of a piezoelectric material using Ansys soft package, and lack the material about it. if anyone has the examples, please send me some, Thank you for your help.
