How to create geometry for TOPOLOGY OPTIMIZATION in spaceclaim

Hey guys, I want to create a custom torque sensor (AKA flat torsional spring) using Topology optimization in ANSYS. The exclusion region for this I want (outside for the outer red line & inside for the inner red line) with the highlighted yellow part to be my design inclusion region. How do I create this geometry in spaceclaim such that I can select these regions to be excluded out of my topology optimization analysis?

    Hi


    You could split the part as needed. The split body, and/or combine design tools (under the design tab) should help here.


    Alternatively one can start in the sketch so that when we extrude we get 3 different parts/regions as needed, and then use the shared topology to connect their faces so we get a compatible mesh between the parts.


    There are many tutorials on the internet for spaceclaim, on how to use these tools.


    Thank you

    Thanks for the reply Erik. From my understanding using the split body command requires me to create a plane, how do i create a circular plane for this object to split it from? Or is my understanding incorrect?

    One can create circular surfaces (say by pulling a circular sketch edge), and then use that to split the body.

    If not easy then you can use the second approach where you create and extrude/pull the different regions and parts and then use the shared topology to connect the faces between them.
