Verification of complex codes

Ober, Curtis C.

Over the past several years, verifying and validating complex codes at Sandia National Laboratories has become a major part of code development. These aspects tackle two important parts of simulation modeling: determining if the models have been correctly implemented - verification, and determining if the correct models have been selected - validation. In this talk, we will focus on verification and discuss the basics of code verification and its application to a few codes and problems at Sandia.
