Employment of hybrid prismatic/tetrahedral grids is a relatively new approach for viscous flow computations with 3D complex geometries. The body surface is covered with triangles, which provides geometric flexibility, while the structure of the mesh in the direction normal to the surface provides th

The derivation of elliptic adaptive grid control functions which satisfy the area equidistribution concept is presented. The resulting expressions are derived without approximation and are shown to provide explicit control over cell area distributions. A modification to the equidistribution concept
Hybrid grids consisting of prisms and tetrahedra are employed for the solution of the 3-D Navier -Stokes equations of incompressible flow. A pressure correction scheme is employed with a finite volume -finite element spatial discretization. The traditional staggered grid formulation has been substit
