| Research Abstract |
With the extensive application of Computational Fluid Dynamics (CFD) technique in various industries, mesh generation for complex geometry is becoming a bottleneck in CFD practical use. Based on VCAD (Volume CAD) Framework, which is developed at RIKEN Institute for storing shape and material attribute data of geometry, we developed a general flow analysis solver, named as V-Flow3D, for three dimensional incompressible viscous fluid flows and heat transfer problems with arbitrary geometries using unstructured grid method. A novel approach has been proposed to deal with the shape of KittaCube of VCAD in Novier-Stokes equation discretization. In this study, the wind environment of buildings is simulated by using V-Flow3D software, and the numerical simulation results show the practical applications of V-Flow3D in the building design and planning.
