%ind_EdgeValue%

In several situations, there is a local pointcloud configuration without interior points. That might happen in airbag applications with only thin layers between the membranes, or it might be due to a degeneration of a 3D-water phase if thin layers of liquid evolve. These situations are characterized by the absence of interior MESHFREE points. A compact thin layer of numerical MESHFREE points does not harm the numerics, but if this layer ends blindly (edge of an airbag or water front of a thin film), this can lead to numerical problems. Hence, here we try to, at least, mark these blindly ending thin layers of MESHFREE points.

The edge value takes values between 0 and 1 and is a measure for evaluating if the above described problematic situation occurs.

This feature is used so far only for GASDYN applications. For LIQUID applications, i.e. for the evolution of thin 3D-point layers, the edge value is also computed, but we rather use %ind_TearOff% and %ind_IsolationFlag% in order to characterize the configuration of the point cloud.
