Finite and Spectral Element Methods for Modeling Far-Field Underwater Explosion Effects on Ships
… model is using cavitating acoustic finite elements (CAFE) and more recently cavitating acoustic spectral elements (CASE). The use of spectral elements in CASE has shown to offer the greater accuracy and reduced computational expense when compared to traditional finite elements. However, …

Low-order finite element preconditioner for spectral element pressure solver in Navier-Stokes equations
High-order spectral element methods (SEM) while very accurate for computational fluid dynamics (CFD) simulations can be prohibitively expensive for meshes with difficult geometries. Controlling the number of iterations in the pressure solver can significantly reduce the computing time of CFD …

The Complex Spatiotemporal Dynamics of a Shallow Fluid Layer
… differential equations are solved using parallel spectral element methods. Rayleigh–Bénard convection is studied in a cylindrical dish with realistic boundaries. The complete flow field is obtained as well as the spectrum of Lyapunov exponents and Lyapunov vectors. The Lyapunov exponents and their …
