New Computer Efficient Approximations of Random Functions for Solving Stochastic Transport Problems

A new grid approximation of a homogeneous isotropic random field with a given average correlation length is developed. The approximation is constructed by partitioning the coordinate space into an ensemble of cubes whose size reproduces the average correlation length in the case of a field value cho...
