[Tochnog-users] new tn version

[roddeman <den...@fe...>]

Hello All,


I installed a new tochnog version a moment ago. 

It contains now the Matsuoka Nakai yield surface, which seems to run
more stable then the classical Mohr-Coulomb. Consider trying MN in your
calculations.


Thanks to mails of Narentorn Yingyongrattanakul and Ivo Herle I found an
error in the convergence behaviour of the trusses. That is corrected
now. (Those wo did calculations with trusses before which converged
should not be concerned, since the right hand side was ok, only the
matrix used for iterations contained an error).



Although a bit early, have a fine Xmass and new year,

Dennis
