A FDM solver for DNS of turbulent flows, based on Moin and Rai's paper. The interpolation is still linear, the authors had used cubic interpolation. Some part of the code is based on Seibold's MATLAB solver as well. Current Boundary conditions are for lid driven cavity flow. Execution speed isn't exactly a strength, and no post processing is currently present. Also the solver does not give an explicit solution for pressure, pressure needs to be computed from phi, an additional step that hasn't been implemented.
