Dear All, When I specify my expansion type as GLL_LAGRANGE or GLL_LAGRANGE_SEM, I see in the grid that the spectral elements are divided in an equispaced way. As far as I know, for GLL expansions the grid should be divided as getting finer through the edges. Is there any other way that Nektar++ handles this issue? Regards, Kamil
Dear Kamil, The output routines interpolate the data onto an equispaced grid for better visualising. However when solving the PDE we do indeed use the GLL points. Cheers, Spencer.
