Creating Global Sensors

This task shows you how to create global sensors, available for the entire model.

The global sensors can be used either in a mono-occurrence solution (static solution, combined solution) or multi-occurrence solution (multi loads static solution, frequency solution, buckling solution).

  • Open the sample08.CATAnalysis document from the samples directory for this task.

  • Compute all the solutions.
    To do this, click Compute and select the All option.

Mono-occurrence Solution

  1. Set the Static Case as the current one.

    To do this, refer to Changing a Current Analysis Case.

  2. Right-click Sensors.1 in the specification tree and select Create Global Sensor.

    The Create Sensors dialog box appears.

  3. Select the desired global sensor.

    In this particular case, select the Energy global sensor.

  4. Click OK.

    An Energy object appears in the specification tree.

    You can edit a parameter to change the name or to visualize the associated value.
    To do this:

    1. Update the sensor you just created.

    2. Double-click the knowledge parameter in the specification tree.

      The Edit Parameter dialog box appears.

    3. Click OK.

    You can display the value of knowledge parameters in the specification tree.
    To know more, refer to Displaying Values of Sensors.

 

Multi-occurrence Solution

  1. Set the Frequency Case as the current one.

    To do this, refer to Changing a Current Analysis Case.

  2. Right-click Sensors.2 in the specification tree and select Create Global Sensor.

    The Create Sensor dialog box appears.

  3. Select Frequency and click OK.

    A Frequency.1 sensor appears in the specification tree under the Sensor.2 object.

  4. Edit the frequency global sensor.

    To do this, double-click Frequency.1 in the specification tree.

    The Global Sensor dialog box appears.

    • Name: lets you change the name of the sensor.
    • Occurrences: lets you preserve the selected occurrences.
      To know more, refer to Selecting Occurrences.
  5. Select the All as Occurrences option.

    You can visualize the occurrences you have chosen.
    To do this, click Edit Filtered Occurrences .

    The Solution dialog box appears.

  6. Click OK in the Solution dialog box and then in the Global Sensor dialog box.

  7. Update the Frequency global sensor.

  8. Double-click the Frequency List object in the specification tree.

    The List Edition dialog box appears.

  9. Click OK in the List Edition dialog box.
