Math File

The Math file (.mth) is a binary spline representation of the Nominal file. PC-DMIS Blade need this file for analysis of airfoil sections.

Be careful when you update the Nominal file that is used to create the specified Math file, since the Math file is NOT automatically updated when its corresponding Nominal file is updated. Re-create Math file when Nominal file is modified.

To create a Math file from a Nominal file, follow these steps:

  1. Select Create | Math, or click the Create Math File button on the toolbar. This opens the Convert NOM to MTH dialog box.
