Unable to scope surface-body edges (named selected) as contact side

    • Miguel

      Hi there,

      I am trying to define the settings of different contact regions and I find Mechanical does not allow me to select some surface-body edges as the contact side:

      I do not understand what´s the problem since it worked fine in another two similar cases:

      Any idea why or what/where the problem could be?

      Please check if the topology is shared at these locations.

      Hi Ashish. Thanks for your reply.

      No: it´s not shared where I try to establish the contact (leg surfaces end-edges and washer-face):


      It is share where it should be, between the leg surfaces and the tip body:

      Meanwhile I managed to go ahead with a "trick": I moved the washer 0,1mm away from the edges creating a small gap between them with the idea of establishing contact using the setting "adjust to touch". Apparently it worked (even though this geometric modification setting is not available ¿?):

      However I am not very confident about it and not sure this is making a working valid contact...

      Any other suggestions/recommendations?
