Place and evaluate sensors

Place a sensor

1. In the Simulation Navigator, right-click the Sensors node (under the Response Dynamics solution process node) and choose New Sensor. Or choose Response Dynamics tab→Response Dynamics group→Sensor .

2. From the Type list, select the type of response results to calculate.

3. In the name box, type a descriptive name for the sensor. This name identifies the sensor in the Simulation Navigator.

4. Select one or more nodes on the model where you want to see response results. Each node you select will generate a response function when you evaluate the sensors.

5. Under Direction, select the method for specifying the direction in which results will be evaluated.Component — Lets you specify the direction of the sensor by selecting the component DOFs in the nodal displacement coordinate system.Direction — Lets you specify the direction of the sensor by specifying a vector.Normal — Creates the sensor normal to the element faces associated with the node on which you place it.Note: The Normal option works only if you place the sensor on an exterior node (a node on the free face of an element). To determine the normal for the node, the software creates a virtual reference face using the nodes from the surrounding element free faces. The Normal option is intended for free element face regions that are tangent continuous. Using it on corner locations may give unexpected results and is not recommended.

6. Under Direction, select the direction components in which to evaluate the results (if using a Component sensor), or specify the vector in which to evaluate the results (if using a Direction sensor).

7. Click OK.The location of the sensor is indicated on the model with a graphical symbol:Note: To change the size of the symbol, right-click the sensor object in the Simulation Navigator and choose Style. In the RS Edit Display dialog box, drag the Scale slider to change the symbol size.

Evaluate the sensor

Note:

You must create an event and excitation before you can evaluate sensors.

1. In the Simulation Navigator, right-click the active event node and choose Evaluate for Sensors.

2. In the graphics window, select the sensor(s) to evaluate. Or, choose List Selection in the Evaluate Sensors dialog box and select the sensors from the list.

3. Under Output Setting, select the method for displaying and/or storing the generated response function. Store to AFU — Saves the generated response function(s) to an AFU file. The AFU file is created automatically with the same name as your simulation file, in the working directory where your simulation file is located.XY Graphing — Plots the response function as an XY graph in the graphics window.

4. If you selected Store to AFU, type a prefix in the Record Name Prefix box to identify this function record in the AFU file.

5. Click OK. The software generates a response function for each nodal location you defined in your sensor. The response functions appear under the Response Functions node, under the event node in the Simulation Navigator. Transient_Event_1 Excitations Excitation_1 Modal Response Response Functions Sensor_1_1_(56Z+)1 Sensor_1_2(1Z+)_1

6. To plot a sensor response function, double-click the function name (for example, Sensor_1_1_(56Z+)_1 in the example above) under the Response Functions node.
