ANSYS Fluent 6326 — Overview and Key Points
ANSYS Fluent 6326 is a version of the Fluent computational fluid dynamics (CFD) solver packaged within the ANSYS suite. Below is a concise, focused summary suitable for documentation, a technical report, or a product brief.
2. Neural Field Solver for Multiphase Flows
A fully differentiable physics-informed neural network (PINN) engine replaces traditional VOF (Volume of Fluid) models for certain interfacial flows. Benefits include: ansys fluent 6326
- Sub-grid interface reconstruction without geometric errors
- Automatic phase change modeling (evaporation/condensation) at molecular scale
- Real-time uncertainty quantification (UQ) for cavitation prediction
Step 2 – Solver Setup
In Fluent’s Solution tab:
- Solver type: Pressure‑based, transient (Δt = 0.005 s, 20 inner iterations).
- Turbulence: Transition SST (4‑equation).
- Multiphase: No, single‑phase water, but enabled cavitation using the Schnerr‑Sauer model because the dead leg pressure dropped near vapour pressure.
- Boundary conditions: Pressure outlet at main exit, no‑slip walls, adiabatic.

1. Executive Summary
This report details the computational fluid dynamics (CFD) analysis conducted using ANSYS Fluent for Case 6326 – a turbulent internal flow through a 90° pipe bend with a sudden contraction (area ratio 2:1). The objective was to evaluate pressure drop, velocity profiles, and secondary flow development. The simulation converged successfully with residuals below (10^-5). Key results include a total pressure drop of 12.4 kPa, a maximum velocity of 6.8 m/s at the bend throat, and strong Dean vortices at the bend exit. Step 2 – Solver Setup In Fluent’s Solution tab:
