Parallel Harmonic Balance for Nonlinear Frequency Response and Modal Analysis in Multiphysics Systems
Please login to view abstract download link
A parallel Harmonic Balance framework is presented for the computation of nonlinear frequency response curves and nonlinear normal modes in geometrically nonlinear elastic systems. Large deformations are modelled using the finite element method with a Green–Lagrange strain formulation, and the resulting nonlinear algebraic system is solved using a Newton–Raphson scheme embedded within a continuation strategy capable of capturing stable and unstable solution branches. The approach is implemented within Quanscient’s cloud-native multiphysics platform Allsolve, enabling scalable parallel computations
