If the nodes for the spectral element method are chosen to be the Gauss-Legendre-Lobatto points, then the resulting mass matrix is diagonal and the method is sometimes then described as the Gauss-point mass lumped finite element scheme. We study the dispersive behaviour of the scheme issue in detail and provide both a qualitative description of the nature(More)
We study the dispersion and dissipation of the numerical scheme obtained by taking a weighted averaging of the consistent (finite element) mass matrix and lumped (spectral element) mass matrix for the small wavenumber limit. We find and prove that for the optimum blending the resulting scheme (a) provides 2p + 4 order accuracy for p-th order method (two(More)
Poultry is the ever-growing food industry in Pakistan and to keep up with the demand of meat it is essential to increase its productivity. The most influencing factors in this regard are the design and orientation of shedsasthey playvitalrole for energy conservation, heating and cooling distribution with controlled temperature and humidity inside the shed.(More)
