Hi Peter!

Thanks a lot for the fast reply! I was wondering if there is a different way to achieve the updating of nodal positions or if NLGEOM is the best way to handle the simulation? (Also do you maybe know where I can find detailed documentation of the NLGEOM setting? I couldnt find much in the contact guide except for some information on how NLGEOM influences the pinball region).

I have tried updating the stiffness at each iteration (Keyoption 10=2) but again the simulation and this setting only work when NLGEOM is activated.
