Design assessment for laser powder bed fusion no longer requires engineers to hand-carry results between preset rules and simulation tools. AgenticDfAM lets language-model agents interpret manufacturing guidance, select tools and propose redesigns, while geometric measurement and numerical comparison stay with executable tools. Across four case studies, three redesign strategies removed all reference violations on an analytical artifact, thermal feedback lowered a bracket's predicted layer-scale peak temperature by 160 °C, and a corrected support-construction procedure was reused in four build orientations.

This work systematically derives a family of algorithms for the LTLT (L unit lower triangular, T skew-symmetric tridiagonal) triangular tridiagonalization of a skew-symmetric matrix X using the FLAME methodology, presents unpivoted and pivoted blocked right-looking, left-looking, and fused variants, identifies new level-2 and level-3 BLAS-like operations, and implements them with BLIS 2.0 packing mechanisms and OpenMP parallelism; experiments show the best implementations greatly exceed the performance of the only known prior software, PFAPACK and Pfaffine, while matching or exceeding related symmetric factorization software.
