• Reduce system of equations and solve – Step 1 → Form K, M, C, and f at the given frequency value (ω i ) → symbolic assembly → .full file – Step 2 → Build A where A(ω i ) = K - ω i 2 M + iω i C – Step 3 → Use subspace Q to reduce A and f at each frequency value→ [Q T A(ω i )Q]y = {Q T f(ω i )} – Step 4 → Solve (dense matrix) reduced system via LAPACK to compute y at each frequency value Project K, C, M, f on Q={v 1, … , v n } to obtain reduced system at frequency ω System of equations in Step 4 will be [dimQ] in rank → extremely fast KRYLOV Method
