Point Wind Monitor*

A Point Wind Monitor can monitor exactly the same quantities as Domain Wind Monitor (see the figure below) however it monitors them only at a particular point of the Domain.


The position of the point where you want to monitor the wind data is specified through a Point Probe attached to the Monitor. In the viewport, the Point Probe appears as a cone pointing downwards with a small flag on top. As shown below, you can specify its coordinates (with respect to the world coordinate system) in its model item and its appearance in its Actor item.

Similar to Domain Wind Monitor, the output data of this monitor will be saved to a PUCD file (AVS compatible UCD file) whose name is specified by the "PUCD File" item. But for a Point Wind Monitor, an additional ASCII file of the same data will also be saved and the name of the ASCII file is specified by the "ASCII File" item. With this ASCII file (the extension is .dat), you can easily retrieve the quantitative values of the quantities of your interest. (Note, however, the positions of the point probes in this ASCII file are with respect to the Extents Coordinate System, which are different from what appear in the Entity Tree of Virtualwind main application, exampled below.)


To create a Point Wind Monitor, access the Monitors  → Create Point Wind Monitor sub-menu item from the Virtualwind main window. A new Point Wind Monitor will then appear in the entity tree under the Monitors item of Atmospheric Conditions.

The current release of Virtualwind supports only one Point Wind Monitor in a simulation (if you create more than one, only the first will be recognized by the solver). However, you can specify multiple Point Probes for this Monitor – therefore still sample the wind information at multiple locations in the Domain. These Point Probes are managed by the PointProbeManager which is a sub-item of the Point Wind Monitor in the entity tree. To create a new Point Probe, right mouse click on the PointProbeManage item and select Create Point Probe from the pop-up menu.
