Towards Scalable Parallel Simulation of the Structural Mechanics of Piezoelectric-Controlled Beams
In this thesis we present a parallel implementation of an engineering code which simulates the deformations caused when forces are applied to a piezoelectric-controlled smart structure. The parallel simulation, whose domain decomposition relies on the finite element representation of the structure, …
