Rotor dynamic analyses have been a focal point for the activities of DELTA JS for many years. An outcome of this is the development of the rotor dynamic software MADYN 2000. DELTA JS grants licences of MADYN 2000, offers maintenance and support contracts as well as training courses.

The capabilities of MADYN 2000 are continuously enhanced according to user feed back. See the release notes for more details about the last versions and the latest version 4.4.

For the analysis of rotor dynamic coefficients for fluid forces the program SEAL2D/3D is offered, which is based on the solution of the Navier Stokes equations. The roots of the program go back to the Technical University of Darmstadt (Prof. Rainer Nordmann). DELTA JS is in the process of enhancing this program for industrial application.
