Detailed Description

Calculate coordinates of cage points and call the class analyticalSol to calculate the velocity boundary conditions at cage points.

This class first calculate the coordinates of pressure, vorticity, and velocity at cage points. Then use their coordinates and values as the input to the class analyticalSol to calculate the velocity components at cage points. Last, use these valocity as the boundary conditions of the finite-difference scheme for the outer flows.
