Good morning to all
I am solving in ansys classic a contact problem of type surface to surface with a hard element (tshape,line) of type targe169 and an element count172. I'm finding problems applying forces to the target element as boundary conditions: It's like she didn't consider them. I thought the problem was in the presence of gap between the elements, which does not allow the transmission of forces. I therefore imposed a minimum penetration pmin, small, as real constant, but the problem persists.
I am forced to impose boundary conditions as shifts, but this method, although more stable from the point of view of convergence, is not always practical. In fact, it does not allow me to check what happens in the state of contact (sliding, sticking, etc.) if you want to have tangential forces acting from the outside.
Does anyone know how to solve this problem?
Thank you.
