If you’re a current CST Studio Suite customer, you can now grab the new 2020 release at software.3ds.com (remember to install the “Golden” base level before any “SP’s”)!

CST Studio Suite is updated for 2020, and it now includes access to the powerful low-frequency solvers of Opera, an excellent choice for motor design among other things!  Visit our CST Studio Suite page to learn more about CST or contact us for a demo.  You can also try the free Student Edition!
