Keywords: Radial basis function Immersed boundary method Spectral method Gibbs oscillation Incompressible viscous flow Navier–Stokes equations Projection method a b s t r a c t It is known that, when the immersed boundary method (IBM) is implemented within spectral like methods, the Gibbs oscillation seriously deteriorates the calculation of derivatives(More)
Simulation of local atmospheric flows around complex topography is important for several applications in wind energy (short-term wind forecasting and turbine siting and control), local weather prediction in mountainous regions and avalanche risk assessment. However, atmospheric simulation around steep mountain topography remains challenging, and a number of(More)
