Thanks for all your responses, Roy, what you said is true about real elastic contact. My implementation(& my geometry) for elastic-rigid contact problem is still very elementary. If someone wanted to do a real elastic contact with for example "conforming profiles" (e.g. a ball on a curve or so

Hi Ataollah, this type of problem is indeed called a 'contact problem'. I don't know how to solve them, neither in libmesh nor otherwise. Anyways, here a short recent discussion about it on libmesh-users: http://comments.gmane.org/gmane.comp.mathematics.libmesh.user/3377 Mauro At Sun, 3 Mar 20
