Hello,

Is there an equivalent in Comsol 4.0 of the option Large Deformation of the previous version (3.5a) ?

I'm trying to see the effect of residual stresses on the stifness of a thin membrane, which I could see with the option LD ON, but with the new version I don't see it!

Thnak you
Elodie

the option that matches with the largue deformation in 4.0 is simply to type include non linear geometric in the setting of the linear elastic material model. then in order to carry out a prestress analysis the procedure is in the attached file
