Dlubal Rwind

Introduction to Dlubal RWIND

Dlubal RWIND is a powerful software designed for the numerical simulation of wind flows around any building geometry.

Overview

Dlubal RWIND is a state-of-the-art wind simulation software developed in collaboration with PC-Progress and CFD Support. It serves as both a standalone application and an add-on for RFEM and RSTAB, offering a comprehensive structural analysis and design solution. The software employs a digital wind tunnel approach to accurately simulate wind flows around various structures and determine wind loads on surfaces.

Features

Calculation of Wind Flow

• Utilizes the SimpleFOAM solver from the OpenFOAM software package.
• Implements first and second-order numerical schemes.
• Supports turbulence models RAS k-ω and RAS k-ε.
• Considers surface roughness based on model zones.
• Allows for model design via VTP, STL, OBJ, and IFC files.

Intuitive Operation

• Bidirectional interface with RFEM or RSTAB for importing/exporting model geometries and wind load cases.
• User-friendly with drag & drop and graphical adjustment assistance.
• Automatic meshing with optimal utilization of processor cores.
• Environmental object consideration (buildings, terrain, etc.).

Visual Output

• Graphical representation of surface results and flow fields.
• 3D wind flow visualization via animated streamlined graphics.
• Definition of point and line probes for detailed analysis.
• Multilingual user interface for global accessibility.

Transient Wind Flow Calculation

• Utilizes the BlueDyMSolver solver for incompressible turbulent flows.
• LES SpalartAllmarasDDES turbulence model.
• Automatic determination of analysis period and time steps.

Advanced Wind Permeability

• Freely adjustable wind permeability for surfaces.
• Load Wizard for Wind Simulation in RFEM.
• Ability to define wind directions and elevation-dependent wind profiles.

Velocity Vectors and Transient Flow

Basic employs a numerical CFD model to simulate wind flows around objects using a digital wind tunnel. The software offers a transient solver for incompressible turbulent flows.
