Method of retaining shape in solid model during material allocation during topology optimization

摘要

Problem to be solved: to provide a method to hold shape in solid model during material allocation during topology optimization.The method holds the shape in the solid model upon material allocation during topology optimization.A 3D geometric model of a portion having a boundary shape is received.The geometry model is preconditioned to produce a variable mesh mesh and to generate a frozen mesh representing the boundary shape.The geometry model is distributed to a plurality of voxels and the density values are adjusted for each voxel according to the optimization process.The uniform mesh is extracted from the voxel data, and the mesh boil product set between the extracted uniform surface mesh and the variable void mesh is derived.Mesh Boolean summation between the mesh boule product set and the frozen mesh is performed.Selection diagram
