In the Simulate and Generate Wind Loads window of RFEM or RSTAB, you can start the calculation in the Load Cases tab (see the Chapter 'Load Cases'). When you click the [Open in RWIND Simulation] button, you call up the RWIND Simulation program. There you can check the simulation parameters, such as the shape of the simplified model, wind tunnel, etc. If all settings are accurate, you can start the calculation as described in the Chapter 'Calculation' above.
Note
The [Open in RWIND Simulation] function gives you a “backstage inspection” of the simulation. This feature is recommended to calculate one load case in order to verify and calibrate the simulation parameters, if necessary.
At the end of the calculation, you have to decide whether to close RWIND Simulation and return to RFEM/RSTAB or continue studying the results in RWIND Simulation.
To start the calculation without opening RWIND Simulation, use one of the [Calculate] functions.
When you click this button, the “silent” calculation of all load cases by RWIND Simulation is started in the background. For every load case, the progression of the simulation is shown in a panel.
The results are finally transferred to RFEM/RSTAB and the RWIND Simulation panel is closed.
Note
If you want to run a simulation for specific objects of your model, apply a Visibility for them (see Chapter 9.9.1.2 of the RFEM manual) and select the Export active objects only option in the Settings tab (see the Chapter 'Settings'). Then [Calculate All in Background] to apply the analysis to only those objects in the model of RWIND Simulation.
When you click this button, only the load case selected in the table is relevant for the simulation. RWIND Simulation performs a “silent” calculation, but you can follow the progression of the simulation in the panel.
