Capture Use Case: Distance to Wall
Created by: overfelt
Just capturing the details of a use case at the request of ArborX developers, not a bug or feature request.
I have an application where the distance from points in the volume to the nearest wall is required for a turbulence model. One way we would like to calculate these values is to use ArborX to determine a few points on the surface that are closest to each point in the volume and then narrow the distance with a detailed calculation. This will be compared to a PDE based approach at scale and in parallel. In any case, the ArborX approach could be used for an initial guess for a PDE solve which would then be used for the small update to the distance given small mesh motions.
