A Meshless and Matrix-Free Approach to Modeling Turbulent Fluid Flow Dedicated to Professor Karl Stark Pister for his 95th birthday

摘要

A meshless and matrix-free fluid dynamics solver(SOMA)is introduced that avoids the need for user generated and/or analyzed grids,volumes,and meshes.Incremental building of the approximation avoids creation and inversion of possibly dense block diagonal matrices and significantly reduces user interaction.Validation results are presented from the application of SOMA to subsonic,compressible,and turbulent flow over an adiabatic flat plate.
