RWIND 2 | Features of RWIND Basic

Technical Article on the Topic Structural Analysis Using Dlubal Software

  • Knowledge Base

Product Feature

  • Calculation of stationary incompressible turbulent wind flow using the SimpleFOAM solver from the OpenFOAM® software package
  • Numerical scheme according to the first and second order
  • Turbulence models RAS k-ω and RAS k-ε
  • Consideration of surface roughness depending on model zones
  • Model design via VTP, STL, OBJ, and IFC files
  • Operation via bidirectional interface of RFEM or RSTAB for importing model geometries with standard-based wind loads and exporting wind load cases with probe-based printout report tables
  • Intuitive model changes via drag & drop and graphical adjustment assistance
  • Generation of a shrink-wrap mesh envelope around the model geometry
  • Consideration of environmental objects (buildings, terrain, and so on)
  • Height-dependent description of the wind load (wind speed and turbulence intensity)
  • Automatic meshing depending on a selected depth of detail
  • Consideration of layer meshes near the model surfaces
  • Parallelized calculation with optimal utilization of all processor cores of a computer
  • Graphical output of the surface results on the model surfaces (surface pressure, Cp coefficients)
  • Graphical output of the flow field and vector results (pressure field, velocity field, turbulence – k-ω field, and turbulence – k-ε field, velocity vectors) on Clipper/Slicer planes
  • Display of 3D wind flow via animated streamline graphics
  • Definition of point and line probes
  • Multilingual user interface (German, English, Czech, Spanish, French, Italian, Polish, Portuguese, Russian, and Chinese)
  • Calculations of several models in one batch process
  • Generator for creating rotated models to simulate different wind directions
  • Optional interruption and continuation of the calculation
  • Individual color panel per result graphic
  • Display of diagrams with separate output of results on both sides of a surface
  • Output of the dimensionless wall distance y+ in the mesh inspector details for the simplified model mesh
  • Determination of the shear stress on the model surface from the flow around the model
  • Calculation with an alternative convergence criterion (you can select between the residual types pressure or flow resistance in the simulation parameters)

Stand-Alone Program

RWIND 2 is a program (digital wind tunnel) for the numerical simulation of wind flows around any building geometries with determination of the wind loads on their surfaces. It can be used as a stand-alone application or used together with RFEM and RSTAB for complete structural analysis and design.
