Dear all,

Herewith I want to announce the release of the frictional rolling contact model CONTACT version 12.1.

The main changes with respect to earlier versions of the program are as follows:

• Achieved a 100-fold speedup for solving larger normal contact problems.
• Improved the documentation of the viscoelastic part of CONTACT and
  provided an example of its use.
• Distinguished free and premium features in the software, the latter
  requiring a valid license file.

For the full release-notes or more information on the program refer to the website www.kalkersoftware.org.

Regards, Edwin
