Claim 10:
11. A system comprising:
a non-transitory storage medium having instructions of a three dimensional modeling program stored thereon; and
one or more data processing apparatus configured to run the instructions of the three dimensional modeling program to cause the one or more data processing apparatus to
perform a numerical simulation of a three dimensional model of an object to be manufactured using a specified isotropic solid material,
compute changes in internal energy for the three dimensional model of the object using results of the numerical simulation with solid elements of the specified isotropic solid material used in the numerical simulation being replaced by representative volume elements that approximate lattice behavior for different lattice design variables comprising at least lattice orientation,
present a set of lattice proposals for the three dimensional model of the object based on the changes in the internal energy,
receive input selecting a lattice from the set of lattice proposals, and
incorporate the selected lattice into the three dimensional model.
