Overview

In this tutorial, we demonstrate how to perform an internal flow CFD analysis of an L-shaped pipe using NFX CFD.  This example covers the complete workflow from geometry preparation to post-processing, allowing users to understand the fundamental procedure for internal flow simulation.

What you will learn in this tutorial:

• Create a fluid domain using CFD Volume Extraction
• Generate and refine the computational mesh
• Apply inlet, outlet, and wall boundary conditions
• Configure solver settings and run the simulation
• Monitor convergence using residuals and monitoring values
• Analyze velocity, pressure, streamline, and vector results
• Evaluate flow behavior and pressure loss in the curved pipe section

The L-pipe model is a common benchmark example for learning internal flow analysis because it clearly demonstrates flow development, velocity changes, and pressure loss caused by pipe curvature.

This tutorial is ideal for beginners and engineers who want to learn the basics of CFD analysis using NFX CFD.
