Syntax

v := extrude.block.grid.pos(bp,ii,ij)

The function only applies to regular (3- or 4-sided) blocks with structured mesh.

Get a gridpoint position. Returns a 2D vector of the $$x$$,$$y$$ position of indexed gridpoint (i,j). Values of i and j will range between 0 and extrude.block.zones.i and extrude.block.zones.j, respectively.

Returns: v - 2D vector bp - block pointer ii - index i ij - index j
