ABSTRACT
This article presents a visualization-assisted process that verifies scientific-simulation codes. Code verification is necessary because scientists require accurate predictions to interpret data confidently. This verification process integrates iterative hypothesis verification with comparative, feature, and quantitative visualization. Following this process can help identify differences in cosmological and oceanographic simulations.
INDEX TERMS
visualization in earth, space, and environmental sciences; hypothesis testing; visual evidence; feature detection and tracking; computer graphics; graphics and multimedia
