STKO V3.0.0 is now available for download

STKO v.3.0.0 was released in early May. Our team was enthusiastic about sharing this version with our STKdOers, as many of the tools and improvements were things you had suggested and asked for over the years. We appreciate our long-time users who have shared their ideas with us and the newcomers’ enthusiasm for learning the software.

You can download V 3.0.0 from our download page by logging in to your account or by registering for an account if you have never downloaded STKO before.

If you want to learn about the new features included in the STKO v3.0.0 postprocessor, you can watch Dr. Massimo Petracca’s webinar about the update on our YouTube channel.

Version 3.0.0 Change Log
