Compliant Gripper in ANSYS

[brango]

Hello,

This is my first post. Sorry if im posting in the wrong place, but I didnt know how to find an ANSYS forum.

I need to model a compliant gripper with ANSYS. I got a set of optimum thicknesses (the best thickness for each element) which would produce maximum displacement at the output of the gripper. This was done using genetic algorithms.

Anyway, i want to model it using a 2D beam element. I already tried to, but I couldnt change the thickness for each element. It was one thickness that would apply to all elements.

So, how can I solve this ? Do I have to create lets say N beam elements each having a different thickness ? It would be messy and too long as the number of elements increases.

I can supply you with more info if you need it. Thank you for any advice you can offer.

I forgot to mention, an example of a gripper design is provided in the attachment of the previous post.

The input forces can be shown equal to 100N each (force from human grip).

And the output is at the spring (node 25).

Thank you.
