%ind_EdgeValue%

marker for points at the edge of point cloud configurations without interior points

In several situations, there is a local point cloud configuration without interior MESHFREE points.

airbag applications with only thin layers between the membranes
degeneration of a 3D water phase if thin layers of liquid evolve

A compact thin layer of MESHFREE points does not harm the numerics, but if this layer ends blindly, 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. Note:

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.
