Understanding the Spalart–Allmaras Turbulence Model (and How to Use It in OpenFOAM) Turbulence modeling sits at the heart of practical Computational Fluid Dynamics (CFD). While the Navier–Stokes equations describe fluid motion exactly, directly resolving all turbulent scales (Direct Numerical Simulation) is computationally infeasible for most real-world engineering problems. This is where Reynolds-Averaged Navier–Stokes (RANS)…

Master CFD From Scratch Using Free And OpenTools Step 1: CAD Modelling — Designing the Geometry Every CFD project begins with defining the geometry of the system under study. This process, known as Computer-Aided Design (CAD), involves creating a virtual model of the physical object — be it an aircraft wing, a valve, or…

How Open-Source Software Can Slash Simulation Costs for India’s MSMEs by Over 60% The Micro, Small, and Medium Enterprises (MSME) sector plays a pivotal role in India’s industrial and economic landscape. It is not just a support system for larger industries, but a driver of innovation, employment, and entrepreneurship. Key Contributions of Indian MSMEs:…
