Contact for Simulation & Design Software

(There is also a general contact page with additional imprint information.)

You can find a lot of information on our website, e.g. to learn about our software products. But eventually you want to get into personal contact in order to ask your specific questions concerning your simulation needs.

Note that we have a separate form for quotations.
