Hi ! There is a little bit personal experience about electro-mechanical analysis in Ansys and Coventorware, hope it helps. Both of them offered sequential method to solve electro-mechanical problems, but Ansys have to mesh the air part through the analysis. It makes calculation more complex and time consuming. For Coventorware, there is no need to deal with air part, just simply assign free-space permittivity. Ansys provides another two elements(Trans109 & Trans 126) to solve electro-mechanical problems. More efficient, but hardto apply on complex 3D model. Liang Zhi Hao, NCTU, HsinChu ------------------------------ Greetings, I am currently evaluating both Ansys and Coventorware for purchasing. I was wondering if some of you have had good/bad experiences with the above softwares that you can share with me? Thank you Regards, Cen Yen M. Sc. Candidate University of Calgary
