Method for Treating Discretization Error in Nondeterministic Analysis

A response surface methodology-based technique is presented for treating discretization error in nondeterministic analysis. The response surface, or metamodel, is estimated from computer experiments that vary both uncertain physical parameters and the fidelity of the computational mesh.
