void oofem::GradDpMaterialExtensionInterface::giveDistanceBasedCharacteristicLength ( const FloatArray & gpCoords )

protected

Provides the distance based interaction radius This function is called when averType is set to 1.

The function loops over all user defined nonlocal boundaries to find minimum distance from the GP. Then calculates interaction radius

Parameters

gpCoords The Gauss points' coordinates, whose interaction radius is calculated based on the distance-based averaging approach.
