Topology removes all material

I have a topology optimization study where I would like to design something with minimal weight within a volume, while maintaining a minimum level of natural modes. The optimization analysis runs, but removes all the materials in the design space. It leaves only the interface points that are non-design, and there are no connections between the regions. I have attached here the hypermesh file for reference. Please help, thank you.

    Hi @Bertoni

     

    Can you add a volume fraction constraint and check if that helps?

     

    Instead, you can start with compliance and volume fraction and based on the paths you can remove the material and check the frequencies.
