Applying Mollifyers to Numerically Solved PDE's

ABSTRACT

Approximations of functional derivatives are constructed through a process of mollification. The resultant functional approximations are analytic and are suitable for numerically solving partial differential equations. Since the derivatives are obtained analytically from a smooth approximation of the function, all derivatives at a point are available at any location in the domain during the numerical differentiation.

To demonstrate the workability of the concept, the technique is applied to a hyperbolic PDE, the De Laval nozzle problem in computational fluid dynamics.
