Strain Filter Selection

Strain filters in Vic-2D and Vic-3D are user-defined so that users can select how localized or how averaged the strains will be presented in the data.  The strain filter helps determine the strain gauge size for all of the individual points on the contour plot.  Small strain filters provide better resolution and more localized data.  However, large strain filters increase accuracy because they contain more data which will result in less uncertainty.  This document provides the stain calculation background, explains the effects of different strain gauge filter sizes, and provides strain filter selection advice for different instances.
