Galerkin Method Applicable for FiniteVolume?
I am developing a CFD model of a continuous reactor. The model is threedimensional, cell centered, finitevolume formulation in rectangular domain using Cartesian coordinates. The SIMPLE method is being used with staggered grids. I would like to use the multigrid method to solve the pressure correction equations. I have a few questions about my approach. Is it acceptable to use the Galerkin (A1=R2A2P1) method to generate course grid coefficient matrices from fine grid coefficient matrices or is it better to rediscretize the equations? Is it valid to represent one transfer matrix (R) as the transpose of another (PT) or should R and P be developed separately? Are there compatibility restrictions on R and P matrices that are developed separately? Is it acceptable to use a weighted average restriction matrix R, along with a trilinear interpolation matrix P? Thanks you for your help Scott
