This only activates the reloading of the non-linear terms. Global dealiasing is only achieved by increasing the quadrature points in the expansion definition Sent from my iPhone On 12 May 2024, at 00:15, Alexander Schukmann <alexander.schukmann@protonmail.com> wrote:  This email from alexander.schukmann@protonmail.com originates from outside Imperial.

Hello everybody, I have a quick question regarding the "SPECTRALHPDEALIASING" flag for the IcnNavierStokesSolver within the "SOLVERINFO" tag of the session file. Does this activate local de-aliasing only, i.e. de-aliasing with respect to the nonlinear convection term or are other parts of the equation (mass matrix, diffusive flux etc.) also "overintegrated"? Thanks and all the best Alex Sicher versendet mit Proton Mail<https://proton.me/>. _______________________________________________ Nektar-users mailing list Nektar-users@imperial.ac.uk https://mailman.ic.ac.uk/mailman/listinfo/nektar-users
