5.1.3.7 Probes

Probes

RWIND Simulation provides an option to define locations for results at specific points on the model or within the wind tunnel around it.

Those control points are called “probes”. They can be used to evaluate and manage the result values for both surface and flow field quantities. Those numerical results defined for the RWIND model are also used for the documentation of results in the printout report of RFEM or RSTAB (see the Chapter 'Printout Report'). Probes can be defined for points and lines (see the Chapter 'Chart Along Line'). All sets of probes are shown in the navigator tree.

Point probes can be inserted by means of the Insert menu or the [Insert Probe Points] button which is available in the Current Point Probe section of the panel.

When the function has been activated, the relevant points can be selected by mouse-clicks. The coordinates of the points are displayed in the panel which has a specific layout for this purpose. There you can also modify the object snap, if necessary. When you have selected all points, click [Finish].

The current sample of probe points is denominated 0 - Temporary.

To save it permanently, use the [Save Probe Copy] button below the list of point probes. A new dialog box is opened where you can define the Name of the probe and check the coordinates of each point.

The options of the Data Source Mesh section control to which type of mesh the probes refer to (see the Chapter 'Computational Mesh and Model Simplification').

• Original Model – display of surface quantities on surface mesh (i.e. Results of Finite Volume Mesh option disabled)
• Simplified Model – display of surface quantities on finite volume mesh
• Flow Field – display of flow field quantities on finite volume mesh

For example, the flow field results (pressure field, turbulence, etc.) require different locations of probes than surface results (surface pressure, C_p coefficient).

All probes, i.e. both temporary and saved sets of probes, will be exported to RFEM/RSTAB and can be included in the printout report.

The buttons in the Current Point Probe section of the panel (see image to the left) have the following functions.
