Abstract

Understanding the sensitivity of computational wind engineering (CWE) solutions to simulation parameters facilitates the development of useful solutions. The traditional approach adopted in other fields through verification and validation (V&V) with well-defined benchmarks is not always possible in CWE. Complex flow phenomena in even simple flow conditions are not readily defined analytically or measured experimentally. This study aims to evaluate the sensitivity of CWE solutions to various simulation parameters with a view to identifying the optimal simulation configuration yielding more reliable results with the least computational effort. To this end the study uses the experimental design technique and seeks to verify the optimal size of the computational domain and level of mesh refinement.
