1. A method comprising:
obtaining, by a computer program, one or more load cases and one or more design criteria for a modeled object, wherein the one or more design criteria comprise a build material strength model indicating strength relationships between thickness of an object feature and build angle for that object feature resulting from additive manufacturing using one or more materials;
iteratively modifying, by the computer program, a three dimensional shape of the modeled object in accordance with the one or more design criteria and the one or more load cases, wherein the iteratively modifying comprises applying the strength relationships between the thickness of the object feature and the build angle for that object feature on a per-element basis during numerical simulation of the modeled object to produce a numerical assessment of a physical response of the modeled object; and
providing, by the computer program, the three dimensional shape of the modeled object for use in manufacturing a physical structure corresponding to the modeled object using one or more computer-controlled additive manufacturing systems.
