AITCH is a FORTRAN90 program which solves for flow in an H-shaped region.
More specifically, AITCH is intended to model the geometry needed for a time-dependent flow of an incompressible fluid in a 2D region, under the Navier Stokes equations.
This program is simply an initial sketch of how to divide up the the region in a way that makes it possible to generate a consistent account of the nodes and elements needed to implement a finite element representation of the solution.
