The current study investigates the use of solution filtering and artificial dissipation as stabilization methods for time-accurate computations, notably focusing on how the decoupling of dissipation from integration impacts simulation error. Rewritin

Toward an optimal solver for time-spectral fluid-dynamic and aeroelastic solutions on unstructured meshes

Autor: Nathan L. Mundis, Dimitri J. Mavriplis

Publikováno v: Journal of Computational Physics. 345:132-161

The time-spectral method applied to the Euler and coupled aeroelastic equations theoretically offers significant computational savings for purely periodic problems when compared to standard time-implicit methods. However, attaining superior efficienc
