Dear Prof. Bangerth, [image: wheel-rail.png] Yes all of these formulation I have set it to the simplest possible one, as for the deformable I considered the wheel as the part goes under deformation where for the contact area is is exactly the same as the wheel thickness which is also match the width of the railway.and the stresses are following the linear elastic scheme. (an illustrative picture attached)
