Smoothing calibration data

The Smooth option enables you to operate on a calibration data set to produce data that has a smoother curve. The resulting data set has the same X-coordinate values as the original data set. Abaqus/CAE uses an exponential moving average algorithm to smooth the data; this algorithm is also used by the smooth2 X–Y operator. For more information, see Smoothing an X–Y data object.

  1. In the Model Tree, click mouse button 3 on the data set that you want to convert and select Process from the menu that appears.

    The Data Set Processing dialog box appears.

  2. Select Smooth, and click Continue.

    The Smooth Data Set dialog box appears.

  3. In the Weight field, specify a value for the smoothing parameter. You can specify a smoothing factor between 0 and 1 for the curve; a smaller value produces a smoother curve. The default smoothing factor is 0.75.

  4. If desired, you can retain the original data set and create a new data set when you perform the data conversion. You can also customize the name of the newly created data set.

  5. Click OK.

    Abaqus/CAE smooths the data set.
