Challenges in BCC Structures: Strut Intersection Issues

[giuseppe.iacolino]

Hello everyone,

I’m encountering a challenge while working with ANSYS SpaceClaim for a parametric analysis. Specifically, I’m parametrizing a structure composed of four Body-Centered Cubic (BCC) cells. The goal is to parameterize both the strut diameter and the side length.

As those familiar with this type of structure might expect, when you parameterize the length size, it can eventually lead to the struts intersecting with each other. The core issue arises when I extrude the struts in a direction parallel to the strut’s axis—the center of the cell doesn’t move, causing this unwanted intersection.

Has anyone else faced a similar issue? Any advice on how to resolve this would be greatly appreciated!

Thank you in advance for your help!

Best Regards,
Giuseppe

Hi Giuseppe,

I think in such situation, you might need one more parameter that is center to center distance betweenn cells. This should be first parameter one should change. Then change the other parameters in order. While it is lot of efforts to create C-to-C distance parameters for all cells, it will be easier if you are using pattern tool.
