Claim 47:
48. A system comprising:
a non-transitory storage medium having instructions of a computer aided design program stored thereon; and
one or more data processing apparatus configured to run the instructions of the computer aided design program to:
obtain a design space for an object to be manufactured, a setup for physical simulation of the object, at least one design objective for the object, and at least one design constraint for the object;
iteratively modify both a three dimensional topology of a generative model for the object and one or more outer shapes of the three dimensional topology using a generative design process that represents the three dimensional topology of the generative model as one or more boundaries between one or more solid regions and one or more void regions within the design space, wherein the one or more data processing apparatus are configured to run the instructions of the computer aided design program to effect modification of both the three dimensional topology and the one or more outer shapes of the three dimensional topology by being configured to run the instructions of the computer aided design program to
change a constitutive model for the physical simulation in accordance with a current iteration of the three dimensional topology and the one or more outer shapes of the three dimensional topology being offset inward to define a hollow structure in the three dimensional topology,
perform the physical simulation of the object using the changed constitutive model to produce a physical assessment with respect to the at least one design objective and the at least one design constraint,
compute shape change velocities for the one or more outer shapes of the three dimensional topology in the current iteration in accordance with the physical assessment, and
update the generative model for the object with the generative design process using the shape change velocities;

adjust, after the modification, a thickness of the hollow structure in accordance with the physical simulation, the at least one design objective and the at least one design constraint, while keeping the one or more outer shapes of the three dimensional topology constant; and
provide a three dimensional model of the object in accordance with the three dimensional topology, the one or more outer shapes of the three dimensional topology and the adjusted thickness of the hollow structure, for use in manufacturing a physical structure corresponding to the object using one or more computer-controlled manufacturing systems.
