This chapter presents a structured comparative review of 24 prominent CFD software platforms, encompassing commercial, open-source, and cloud-based solutions. The analysis covers core capabilities including mesh generation, turbulence modeling, multi-physics coupling, GPU-accelerated solvers, and user interface design. Particular emphasis is placed on their applicability to building physics, architectural aerodynamics, and urban environmental simulation. Tools such as FLUENT, OpenFOAM, COMSOL, and SimScale are assessed for their suitability in modeling complex fluid–thermal interactions in both interior and exterior environments. The chapter aims to support researchers, engineers, and architects in selecting appropriate CFD tools for high-fidelity simulation of ventilation, heat transfer, pollutant dispersion, and wind flow around urban structures. Integration with energy analysis platforms and the growing role of multi-physics simulation in sustainable design are also discussed.

摘要

This chapter presents a structured comparative review of 24 prominent CFD software platforms, encompassing commercial, open-source, and cloud-based solutions. The analysis covers core capabilities including mesh generation, turbulence modeling, multi-physics coupling, GPU-accelerated solvers, and user interface design. Particular emphasis is placed on their applicability to building physics, architectural aerodynamics, and urban environmental simulation. Tools such as FLUENT, OpenFOAM, COMSOL, and SimScale are assessed for their suitability in modeling complex fluid–thermal interactions in both interior and exterior environments. The chapter aims to support researchers, engineers, and architects in selecting appropriate CFD tools for high-fidelity simulation of ventilation, heat transfer, pollutant dispersion, and wind flow around urban structures. Integration with energy analysis platforms and the growing role of multi-physics simulation in sustainable design are also discussed.
