Configure the Automatic FFT Setup

In default (Automatic) mode, GM-SYS 3D expands all grids inside the calculation routine each time it runs and then "masks" back to the original size at the end of the calculation. Internal expansion/filling works best for grids that have zero trend, using the default values.

Configure the Automatic FFT Setup

  1. On the Settings menu, select Automatic FFT Preparation. The Automatic FFT Preparation dialog appears.

  2. Enter the Minimum Percentage to Expand Grids. Grids will be expanded by at least this percentage of their original size in preparation for FFT. The default is 50%

  3. From the drop-down list, select the Shape of Output Grids (square or rectangle). The default is rectangle.

  4. Click OK. The requested changes are made.
