ANSYS Mechanical · FEA · 2026 ANSYS Mechanical: Structural, Modal, Explicit & Harmonic Four analysis types, four different questions. A clear, plain-language guide to when to use static structural, modal, explicit dynamics and harmonic response — so you pick the right tool every time. Open ANSYS Mechanical and you're faced with a long list of analysis types — and choosing the wrong one wastes hours or gives misleading results. The good news: four analysis types cover the vast majority of structural simulation work, and each answers a very different engineering question. This 2026 guide explains static structural, modal, explicit dynamics and harmonic response in simple terms — what each one solves, when to use it, and a real example — so both beginners and practising engineers can choose confidently. What This Guide Covers The Four Analysis Types Static Structural Modal Analysis Explicit Dynamics Harmonic Response Sid...

CFD analysis of a double slope solar still lets you predict freshwater yield before building any hardware. In this free tutorial you will simulate a double slope solar still in ANSYS Fluent using the VOF multiphase model and the solar load model, across four short video parts covering geometry, meshing, physics setup and post-processing. Table of Contents 1. Introduction and Governing Physics 2. Part 1 — Geometry and Domain Setup 3. Part 2 — Meshing and Mesh Quality 4. Part 3 — Physics, VOF and Solar Load Model 5. Part 4 — Solution and Post-Processing 6. Validation and Further Work 7. Frequently Asked Questions Introduction and Governing Physics A double slope solar still is a shallow basin of saline water enclosed by two inclined transparent glass covers in a symmetric gable arrangement. Solar radiation passes through the glass and is absorbed at the blackened basin, heating the water. Vapour rises from the free surface, condenses on the...

OpenFOAM · Solver Processing · 2026 OpenFOAM Solver Processing in 2026 The heart of every simulation: how to configure boundary conditions, mesh motion, physics models, numerical schemes and the right solver application to run an OpenFOAM case correctly. Pre-processing builds the mesh; post-processing shows the results — but processing is where the physics actually gets solved. This is the stage where OpenFOAM turns your case files into a flow field, and it's where the most important decisions live: the boundary conditions , any mesh motion , the physics models , the numerics , and the solver application you run. Get these right and the solver converges to an accurate answer; get them wrong and it diverges. This 2026 guide walks through all five, so you can set up the processing stage with confidence. What This Guide Covers What Is Processing? Boundary Conditions Mesh Motion Models Numerics Solver Applications Proce...

CHT · CFD · Fluent / OpenFOAM / CFX Conjugate Heat Transfer (CHT) in CFD Software How to effectively handle coupled fluid-solid heat transfer — what CHT really is, how the coupling works, and exactly how ANSYS Fluent, OpenFOAM, CFX and STAR-CCM+ solve it. A 10 °C error in a chip's junction temperature can mean a recalled product; the same error in a turbine blade can mean catastrophic failure. Yet many thermal models still guess the heat transfer coefficient (HTC) at a wall. Conjugate Heat Transfer (CHT) removes that guesswork: it solves the fluid and the solid together, coupling temperature and heat flux at their shared interface for a true thermal prediction. This guide explains what CHT is, how the coupling works, and — crucially — how to handle it effectively in Fluent, OpenFOAM, CFX and STAR-CCM+ . What This Guide Covers What Is CHT? When to Use CHT How the Coupling Works CHT in ANSYS Flue...
