Hi,

i've a problem with topology optimization. I would like that my nodesign space (that's a shell) is completely connected to optimized design space. How to do that?
I have this situation.

 

Thanks a lot in advance.<?xml version="1.0" encoding="UTF-8"?>2.thumb.PNG.568d42c5a582b8cf329e77f8e466986f.PNG<?xml version="1.0" encoding="UTF-8"?>1.thumb.PNG.beb18f735ec24609ef40b2f751bb2e83.PNG

    Hi,

     

    this geometry found by topology optimization is the most efficient load path for given loads and BCs.

    If for some reason you want to have optimized design connected over the whole shell area then put some adjacent layers of solid elements into non-design space.

    Or change loads and BCs to get the shape you want- some intuition is required.

    How the shell and solid was connected? Did you perform analysis prior to optimization? If possible share the fem file.
