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 an amount such as 83% to compensate. 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, or use the right-click menu.
   Note: Only PRM files that include stress and distortion analysis can be scaled, and a scaled PRM file cannot be scaled again.
   

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. Review the name of the scaled PRM file, revise it if you wish, and then click OK to save the file in the library.

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