  • Systems and methods for simulating distortion and residual stress in an additive manufacturing process
    Patent number: 11663373
    Abstract: Example systems and methods are disclosed for predicting structural distortion in a part geometry created by an additive manufacturing process. An octree mesh is generated for a part geometry based on a voxel file having voxel layers. The octree mesh is coarsened, a representation of stiffness for one of the voxel layers is generated based on the coarsened octree mesh, a force vector is determined based, in part, on the coarsened octree mesh and data from a thermal analysis of the part geometry, and a layer distortion is determined based, in part, on the force vector and the representation of stiffness. The structural distortion in the part geometry is predicted based on the layer distortion.
