摘要: Abstract A class of implicit finite element upwind schemes for solving Euler equations is presented. Steady flows with extreme conditions such as high Mach numbers or/and large angles attack on unstructured meshes can be simulated. Upwind methods are used the spatial approximation. Higher rates convergence obtained by using an scheme relying a linearization fluxes and partial resolution systems Gauss-Seidel algorithm. The that we get more efficient robust than explicit time integration.
