That shouldn't be the case. What exactly is the error? Did you set the boundary ids when you created the mesh? > To get around this, I was wondering if I could fix the individual dof to a > specific value. Any suggestions to make above work is appreciated. You can manually add a constraint row for each boundary dof, or you can use a penalty method. --- Roy _______________________________________________ Libmesh-users mailing list Libmesh-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/libmesh-users
