For the various needs of rotordynamic engineering DELTA JS disposes of the inhouse developed commercial software MADYN 2000 ® including modules for magnetic bearings, fluid film bearings, rolling element bearings and seal analyses.

The roots of some modules go back to cooperations with universities. They have been further developed for industrial use.

The CFD code for fluid film bearing analyses is based on ALP3T, which is a result of more than 20 years of research mainly of Prof. Glienicke sponsored by the German research consortium Forschungsvereinigung Verbrennungskraftmaschinen. DELTA JS is member of this research group.

The CFD code for seal analyses is based on SEAL2D/3D. Its roots go back to the University Darmstadt, Prof. Rainer Nordmann.

For rolling element bearings MESYS is integrated into MADYN 2000 to calculate linear and nonlinear bearing forces.
