Grid BC Shape Commands

These commands define shapes. All nodes contained with in the shape will be assigned boundary conditions specified within the shape command.

Line

The command to select a line through a 2D mesh in scripted files is:

MoveLine (x1),(y1),(x2),(y2),(tolerance)
  (one or more velocity, temperature, or concentration condition)
    ...
EndMoveLine

In XML files, a line is selected with:

<BCLine units='(units)' x1='(x1)' y1='(y1)' x2='(x2)' y2='(y2)' tolerance='(tolerance)'>
  (one or more velocity, temperature, or concentration condition)
    ...
</BCLine>

where

* (x1, y1) to (x2, y2) define (x, y) coordinates (in mm) for the points at the beginning and end of the line (or (R, Z) coordinates if axisymmetric).
