1. A computer-implemented method for generating models, comprising:
generatively creating, until convergence is reached via a generative design process within a generative design software application, a generative design, wherein the generative design comprises a hollow computer-aided design (CAD) design;
exporting the generative design as a generative shelled base;
creating, from the generative shelled base, a shelled solid body and a mid-surface shell;
creating, from the shelled solid body, a CAD geometry for an internal support structure;
converting the CAD geometry into one or more CAD faces and one or more CAD solid bodies;
creating, from the mid-surface shell, a shell mesh model;
combining the one or more CAD faces and one or more CAD solid bodies with the shell mesh model into a generative mid-surface mesh;
providing the generative-mid-surface mesh to a computer-aided engineering (CAE) crash simulation application for validation of the generative mid-surface mesh;
combining the generative shelled base with the CAD geometry into a generative shelled solid; and
providing the generative shelled solid to an additive build simulation application.
