Checking Parameters
The outline of the wind tunnel is displayed as a box around the model in its centre. You can check the wind direction which is symbolised by a big red arrow. In the View navigator, several options are available to display some items relevant for the wind tunnel (see image to the left). The terrain level results from the value defined in the Model Properties section of the General Data window.
If necessary, you can adjust the size and position of the wind tunnel graphically or in the Wind Tunnel dialog box (see the Chapter 'Wind Tunnel'). Make sure that enough space is provided at all sides of the model for the air to flow unimpededly.
If you have selected the Close openings option (see Section 'Model Properties'), you can check whether the openings or gaps are adequately closed in the model of RWIND Simulation. If necessary, you can modify the settings in the 'Edit Model' dialog box of RWIND Simulation. Note that it will make a considerable difference for the analysis whether the air can flow through an opening or not.
RWIND Simulation features a Simplified Model, which is created from the original RFEM/RSTAB model. It represents a special mesh to define the model boundary (see the Chapter 'Computational Mesh and Model Simplification' for further information).
You can display the simplified model as follows:
- Select the Show Simplified Model option in the panel.
- Select the Simplified option in the View navigator for the Model display.
The degree of simplification is controlled by the Level of detail specified in the 'Edit Model' dialog box. The Chapter 'General' includes an example which shows the effects of this value on the 'shrink-wrapping' process applied to model. If the boundaries are not represented properly, you can adjust the level. When you click [Apply] in the 'Edit Model' dialog box, you can immediately check the modifications and view the new simplified model. Note that a very detailed model will accordingly require more computational time.
