hello everybody and thanks again for help on my previous post. i am now having sever difficutlies with implicit and the contacts. basically i am trying to model a stent (see my mass scaling post) whcih expands inside an artery, modelled as a simple tube of hyperelastic material. i am running implicit, and have set up the contact definitions with the artery as the slave and teh expanding stent as the master. The job runs until contact is made, but abrots soon after. Some deformation does occur, but then i just get the "too many attempts on this increment error". I have tried reducing the increment size and also switched bewteen finite and small sliding. i have also refined the mesh of the slave surface to great extent as hinted in the user guide.
Again thanks in advance for your help.
