A Matrix-Free Galerkin Multigrid Solver and Failure-Mode Screen for Single-GPU 3D SIMP Linear Systems
Shaoliang Yang, Jun Wang, Yunsheng Wang
Large 3D SIMP studies require repeated elasticity solves for density-dependent operators whose finest matrices are expensive to assemble and whose conditioning degrades under high…

Matrix-Free 3D SIMP Topology Optimization with Fused Gather-GEMM-Scatter Kernels
Shaoliang Yang, Jun Wang, Yunsheng Wang
The matrix-free gather-batched-GEMM-scatter pattern eliminates global stiffness assembly for three-dimensional SIMP topology optimization, but the conventional three-stage implemen…

AutoSiMP: Autonomous Topology Optimization from Natural Language via LLM-Driven Problem Configuration and Adaptive Solver Control
Shaoliang Yang, Jun Wang, Yunsheng Wang
We present AutoSiMP, an autonomous pipeline that transforms a natural-language structural problem description into a validated, binary topology without manual configuration. The pi…
