A Spectral Element Solver for Structural Health Monitoring Application
A solver based on the spectral element method, used in conjunction with FEMAP, as a pre- and post- processor. It solves the elastic wave propagation problem, and the coupling with a piezoelectric materials for excitation and sensing. It is currently in 2D and has both static and transient capabilities.
