This paper presents a generalized and simple implicit interpolation scheme at algebraic level for the coupling of non-conforming meshes in computational fluid dynamics (CFD). The final equations for most of numerical methods are always of an algebraic form and that is where the interpolation process...
Further, the accuracy and robustness of the scheme in 3D is demonstrated by computing the flow past an ONERA M6 wing and a clipped delta wing with aileron deflection. The computed results show good agreement with wind tunnel experiments and other CFD computations....

8.4.2.2.2 Explicit scheme In contrast to implicit methods, explicit solution techniques are only conditionally stable requiring very small time steps to obtain a numerically stable solution. The critical time increment is governed by the highest frequency in the system which is generally associated wit...
(7 nonzero entries per row in A) then the ILU will only require around 54Mb (and significantly less if the matrix entries are constant)*. Also, in gerneral, the number of floating point operations will be lower for a suitably accelerated iterative scheme with a good initial guess compared...
decrease would be at unity, the schemes being to first orde accuracy. However, the magnitude of the fault would be determined by the coefficients of the error terms, and therefore could be different. In general, an implicit scheme is expected to give a lower fault than the explicit scheme....
Another distinguishable deterministic method, which is named unified gas kinetic scheme (UGKS), was proposed by Xu et al. [20–22]. UGKS is a multi-scale method with coupled particle transport and collision in its numerical flux modeling. It is based on an integral solution of the gas-...

Both the grid movement scheme and the moving grid solver are considered. A new grid movement scheme for large amplitude moving boundaries such as store separation has been developed. Some popular grid movement methods have been studied to analyse capabilities of this method. In fact, this scheme ...
