RBF-PHS for Incompressible Flow with application to a Couette Flow

This code was written by Anand Radhakrishnan

This code solves for an incompressible Couette flow between two cylinders, with the inner one rotating at a constant angular speed. The theoretical formulation is in the JCP_Paper.pdf paper in the root directory.

Mesh files .msh in conc_circle_geoms/ were generated with gmsh. The code has 4 main components:

  1. Operator discretization for pressure Poisson with all Neumann boundary conditions in Grid.cpp
  2. Multigrid preconditioned GMRES/ ILU-GMRES solvers in FracStepMultirid.cpp
  3. Fractional Step procedure in fractionalStepGrid.cpp
  4. Main file which generates the simulation in FractionalStepSim.cpp
