I’d like to represent solicitation through rigid pins pulling the piece apart. For this I’d like to try pressure varying along different positions of half of the internal surface of the hole, as per a sine function, can this be done? Also, I think it would be more convenient to consider only half of the geometry, cutting the piece along the neck and fixing the cut surface. For this would it be necessary to upload only half of the geometry or can this be specified in the meshing? Thanks for your guidance.
