Dear DXplorers,
To make {Streaklines} work correctly for an internal flow, I thought it
would be useful to define a flag that is "0" on the wall of the pump
housing and "-1" outside. I created positions & connections & data for the
exterior points, and included them with the actual data before using {Import}.
The idea is that the velocities are genuinely zero on the wall, so they
need to be valid, whereas points outside the wall (where flag = -1) should
be invalidated. I figure this is how to prevent streaklines from passing
through the wall of the pump housing.
My problem is that I can't figure out how to make {Include} work only on
the "flag" field, which is the 2nd member of the group (the first being the
"velocity" 3-vector).
Is there a way to do as I describe, or is there a better way?
Thanks!
