After several decades of development we are happy to announce that the Tochnog Professional finite element program has become free. Both for academic and commercial use. We are extremely grateful to some large companies who have supported development. Tochnog Professional enables powerful and flexible calculations for geotechnics and civil engineering; many modern hypoplasticity laws are readily build in (no umat linking is needed).

We will take care of further development and maintenance in the years to come. For the Tochnog Professional homepage see http://www.tochnogprofessional.nl.
