Claim 0:
1. A method comprising:
performing, by a three dimensional modeling program, a numerical simulation of a three dimensional model of an object to be manufactured using a specified isotropic solid material;
computing, by the three dimensional modeling program, 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;
presenting, by the three dimensional modeling program, a set of lattice proposals for the three dimensional model of the object based on the changes in the internal energy;
receiving, by the three dimensional modeling program, input selecting a lattice from the set of lattice proposals; and
incorporating, by the three dimensional modeling program, the selected lattice into the three dimensional model.
