Derived Point Imported Model Data Sets

Derived point imported model data sets hold a time history, FIR Filter function or Fourier transform.

They are used to visualize data at a point on a surface that is imported from a .trn file (see also Importing Surface Spectral Data), a .simh file, or the Fourier transform. The Point imported node represents a derived point imported model data set in the simulation tree.

This object cannot be deleted while a link is in place from derived data sets in a plot. This object shares pop-up menu items with other derived data sets.

The function definition requires:

• Importing the surface from an existing .trn or .simh file.
• Extracting a field function from that surface.
• Selecting a point part as a probe.

The above quantities can be specified using the properties of this object. If the Update Active property is activated, the point time history or point time Fourier transform is calculated after the last property assignment. Alternatively, you can calculate the transform by right-clicking the Point imported node and selecting Update Output, irrespective of the state of the Update Active property.

Derived point imported model data sets are not updated automatically when you change a part position. A modified part can have many associated derived point imported model data sets. An automatic update would take some time and cause the Simcenter STAR-CCM+ user interface to lock until the process is complete.

When any part is modified, all of its derived point imported model data sets are shown as requiring an update. The Update Active property for the affected derived point imported model data sets is automatically deactivated.

• To update a derived point imported model data set, do one of the following:
  • In the Properties window, manually activate the Update Active property.
  • Right-click the derived point imported model data set and then click Update Output.
