Every now and then I look for new extensions that Ansys can support. Some time ago this software package allowed for third party extension development but there weren’t many to choose. Since then things have evolved a great deal. Browsing through the internet I discovered that CADFEM has been working hard on this subject and offers a few extensions as its products. They are not all purpose extensions and have a very specific purpose in some cases like moulding specific calculations. Aside from these which I showed Ansys site offers quite a big set of plugins also, some free others paid.
