Free Engineering Simulation Tutorial - Opensource Software & Simulation Guides

Here's the problem every CFD engineer hits with the ANSYS Fluent fan model: the manufacturer gives you a fan curve of pressure vs flow rate (P–Q) — but Fluent's fan boundary condition wants pressure jump as a polynomial function of velocity . Enter the raw flow data and you get wild, unrealistic velocities. The missing step is converting flow to face velocity and fitting a polynomial. This free Fan Curve to Fluent Calculator does exactly that: paste your fan curve, enter the fan area, and get Fluent-ready pressure-jump coefficients (and a piecewise-linear profile) you can drop straight into the Fan dialog.

Ever sat in a project meeting where the HVAC consultant rattles off "we need 120 TR, 40,000 CFM at 2 inches static" — and half the room quietly nods without a clue? HVAC is full of jargon that MEP consultants use daily but owners, architects and clients rarely understand. This guide fixes that: a plain-English glossary of the most important HVAC terms so everyone can follow the conversation — plus a free HVAC Unit Converter for the conversions consultants do constantly (TR ↔ kW, CFM ↔ m³/hr, inWG ↔ Pa, and more). Table of Contents The HVAC Unit Converter Why These Terms Matter Cooling Capacity Terms Airflow & Pressure Terms Equipment Terms (AHU, FCU, VAV…) Efficiency & Heat Terms Quick Conversion Table FAQ The HVAC Unit Converter Pick a category, type a value, and get the converted result instantly. Built for the imperial↔metric conversions MEP consultants use every day.  HVAC Unit Converter C...

ANSYS Fluent · CFD Tutorial Fan Boundary Condition in ANSYS Fluent: Ceiling Fan CFD Model a ceiling fan in a room without meshing a single blade — using Fluent's fan boundary condition and its pressure-jump model. Full workflow from geometry to airflow results. How do you simulate a ceiling fan pushing air around a room in CFD — without the nightmare of meshing and rotating the blades? The answer is one of Fluent's most useful and underrated tools: the fan boundary condition . It replaces the whole fan with a thin surface that simply adds a pressure rise to the flow, capturing the fan's effect at a tiny fraction of the cost. This tutorial walks through a complete ceiling fan simulation in ANSYS Fluent — geometry, named selections, mesh, adding the fan boundary condition, and reading the airflow — with screenshots from the full video.
