Abstract:

INMESH is a computer program for the generation of two-dimensional boundary-fitted coordinate systems. This general program creates a numerical transformation which maps an arbitrary region in physical space onto a regular region with a uniform grid in computational space. The computational region may consist of one or more segments joined together so that any topological complexity in the physical region, such as multiple-connectedness, is suitably resolved. Numerical solutions of partial differential equations may be obtained from this computational field regardless of boundary shape. Emphasis is placed on ease of use and interactive graphics so that a mesh can be generated quickly, viewed interactively, and regenerated immediately with slight alterations until a suitable mesh configuration has been obtained. A brief explanation of the method is given along with a detailed description of the input required to produce boundary-fitted coordinate systems. Several sample meshes are shown for configurations involving foil-like bodies. Additional keywords fluid dynamics problem solving. Author
