This is well described in the doc, but very easy to forget while programming<br /> <br /> Good luck<br /> Ivar Sat, 13 Mar 2010 06:18:08 +0000 3790.1268461088.9886 http://www.comsol.fr/community/forums/general/thread/3790/#p9877 <br /> How would I model the shear stress slip and direction in a crystal? In other words, if I have all the necessary material information how can I use the 3D structural mechanics module in Comsol to figure that out.<br /> <br /> Thank you Fri, 12 Mar 2010 23:53:28 +0000 3790.1268438008.9877
