目前，用于 RWIND 3 的模型可以在 RFEM 6 或 RSTAB 9 中创建，或者从 STL 文件（例如地形和其他对象）或其他格式的文件中导入，见章节{%！005714导入模型]]了解更多信息， The wind loads applied in specific directions (see the description below) result in corresponding load cases. Each direction represents one model in RWIND 3. After the calculation, the models are saved in the "RFEM 6 / RSTAB 9" project group. For the analysis, the models are exported to RWIND 3 where the loads are determined. The denominations of each model (Project) include the names of the RFEM 6 / RSTAB 9 models and the load case numbers.
You can open any RFEM 6 or RSTAB 9 model to examine the results. Additionally, you can modify the calculation parameters, move or rotate the model, or insert the geometry of the terrain (in development, see Chapter Model Type).
In RWIND 3.03, the calculation of the flow in an empty tunnel is enabled . This allows the user to verify the calculation of the flow field with different turbulence parameters, maintaining the flow and turbulence parameters throughout the domain and to compare the results with other programs or experimental data.
