To Scale a PRM File

Doing this can improve the accuracy of simulations

As experience develops with the use of a particular stress and distortion PRM file, you may discover the need to improve the model's correlation with reality. For example, if distortion of parts is about 20% higher in simulations than in actual builds, you may want to scale the stress and distortion PRM file by 83%, assuming a linear behavior. To improve the accuracy of future simulations, you can scale a PRM file up or down, as follows:

  1. On the Home tab, click Processing Parameters.
  2. In the dialog, select the PRM file to be scaled, and then click Scale. Only PRM files that include stress and distortion analysis can be scaled.

  3. Enter a Scale Factor, based on 1.0 as the current value in the PRM file. For example, set a value of 0.5 to reduce the factor by half, or 1.2 to increase it by 20%.

  4. Enter a descriptive name for the scaled PRM file, and then click OK to save the file in the library.

    The new scaled PRM file has _scaled appended to the file name.
