Objectives   

1.      Verify the provided m-file template for the GWSh DM algorithm for quasi-one dimensional potential fluid flow in a variable area duct.

2.      Solve for the potential function distribution and post-process this solution for pressure and velocity distributions on the base mesh.

3.      Perform a mesh refinement study, verify asymptotic convergence in the energy norm using log scales, hence determine the mesh M necessary to produce engineering accuracy for the pressure solution ph(x).
