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 shelled base, wherein the generative shelled base comprises a hollow computer-aided design (CAD) three-dimensional (3D) design;
creating, from the generative shelled base, a shell CAD geometry and a shell mesh model;
creating, from the shell CAD geometry, a support structure mid-surface shell of an internal support structure for the generative shelled base;
combining the support structure mid-surface shell 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 shell CAD geometry into a generative shelled solid; and
providing the generative shelled solid to an additive build simulation application; and
wherein the shell CAD geometry is used to create both the generative mid-surface mesh that is used by CAE crash simulation application, and the generative shelled solid that is used by the additive build simulation application.
