RWIND

What is RWIND?

CFD-based wind load generation for any type of structure

Do you always know the direction of the wind? It's the meaning of innovation, of course! With RWIND 2, you have a program that uses a digital wind tunnel for the numerical simulation of wind flows. The program provides these flows around eventual building geometries and determines the wind loads on surfaces.

Functions of RWIND Basic

Calculation of transient incompressible turbulent wind flows using the SimpleFOAM solver from the OpenFOFOAM software package.

Numerical scheme according to the first and second orders

Turbulence models RAS k-ω and RAS k-ε

Consideration of surface roughness depending on model zones

Elaboration of models through VTP, STL, OBJ and IFC files

Operation through two-way interface of RFEM or RSTAB for the import of model geometries with wind loads based on standards and export of cases of wind loads with tables of print reports based on probes

Intuitive model changes with drag-and-drop and graphical adjustment aids

Generation of a shrink-wrap mesh wrap around the geometry of the model

Consideration of objects from the surrounding environment (buildings, terrain, etc.)

Description of the wind load as a function of height (wind speed and turbulence intensity)

Automatic adjustment of meshes according to the selected depth of detail

Consideration of layer meshes near model surfaces

Parallelized calculation with optimal utilization of all cores of a computer's processor

Graphical output of surface results on model surfaces (surface pressure, Coefficients Cp)

Graphical output of flow field and vector results (pressure field, velocity field, k-ω turbulence and k-ε field turbulence, velocity vectors) in the Clipper/Slicer planes

3D wind flow visualization through animated dynamic graphics

Definition of sample points and lines

Multilingual use of the program (German, English, Czech, Spanish, French, Italian, Polish, Portuguese, Russian and Chinese)

Calculations of multiple models in a batch process

Generator for creating rotated models to simulate different wind directions

Optional stop and continuation of calculation

Individual color panel per results chart

Diagram visualization with separate output of results on both sides of a surface

Dimensionless distance output from y+ wall in mesh inspector details to simplified model mesh

Determination of the cutting stress on the model surface from the flow around the model

Calculation with an alternative convergence criterion (the user can choose between the types of residue pressure or resistance of the flow in the simulation parameters)
