A variant of the finite superelement method for computing viscous incompressible flows
L. G. Strakhovskaya Keldysh Institute of Applied Mathematics, Russian Academy of Sciences, pl. Miusskaya 4, Moscow, 125047, Russia
Abstract:
A variant of the finite superelement method (FSEM) is proposed for computing viscous incompressible convection-dominated flows on a triangular unstructured mesh. To construct the high-order FSEM scheme, vector polynomial test functions (SE basis) are calculated in each grid cell by solving the linearized Navier-Stokes equations with special boundary conditions in the form of basis functions in the trace space.
Key words:
finite superelement method, Navier-Stokes equations, unstructured meshes, vector basis, implicit scheme.
