Hello everyone,
First I ask you my problem: in ansys workbench mechanical in particular in a structural analysis 3d, I created three bodies: two line element with its rectangular cross section, while a third is a simple surface with thickness>0, as well as in figure
the study plans to fix one head and apply one force to another to assess the rising tensions in the connecting element.
My problem concerns the connections of the three bodies, as trying to create for example a connection between the first element at the top and the upper edge of the surface this is what happens:
- "manual contact region" does not support line body, or rather takes them as target, but does not reach convergence.
- "manual mesh" connection does not support a line body as a target for connection.
- "fixed joint" creates too many rigid constraints between the bodies and nothing moves.
- "spot weld," like above.
when I split the line body and surface edges with the split edge command in dm to create a number of vertices to connect to make the connection as from image:
learned this, I suppose that the ideal would be to connect the individual knots through an equal number of "spot weld" in such a way as to allow the expansion of the material keeping the distance between the connected knots, perhaps bringing the numbers of divisions to the infinite;
But you understand that I would put an eternity to connect all created knots individually. ergo, do you have any solution to make this type of joint? any trick, anything that saves me the effort to create 1000 different welds for every single knot?
Thank you so much in advance!! !
