Create negative of a mesh

I have an existing 3D tetrahedral mesh of a lattice structure, and I want to create its negative, resembling the matrix of a composite material. My goal is to start with a cuboid and subtract the existing lattice mesh from it to obtain a new mesh where the nodes and faces align with the original mesh. Can someone guide me on how to achieve this? Thanks!

    Hi Pietro
    there might be some options

    -you can try mesh boolean operations on solid mesh

    -take faces of 3d lattice and connect to cubiod shell surface mesh, once you have closed shell mesh you can fill with tets
