I have recently downloaded the MEMS ACT module.<\/p>\n<p><\/p>\n<p>I am exciting the entire system with an acceleration [A*sin(wt)similar to base excitation]. So, potentially this excitation should result in the mechanical vibration of the system and an open circuit voltage development across the piezoelectric patches which I wish to tabulate as a function of time (attached schematic). However, I am finding it difficult to set it up in ANSYS workbench. There seems to be dearth of examples in the internet. Any help or pointing me towards examples would be very helpful.<\/p>\n<p><\/p>\n<p>I have attached my project here, where I am able to extract the deformation\/deflection of the system due to the imposed acceleration. However, I am unable to figure out how to extract the time vs voltage information across the bimorphs at either clamped ends.<\/p>\n<p><\/p>\n<p><img decoding=\"async\" src=\"https:\/\/us.v-cdn.net\/6032193\/uploads\/attachments\/14cb74fc-2682-4005-b37a-a934014fd1e8\/82f92729-cac5-465b-b34f-a9ee00643b6a_schematic-of-the-structure.jpg?width=690&amp;upscale=false\" alt=\"\"><\/p>\n<p><\/p>\n<p>P.S.
