Function/Subroutine Documentation

subroutine gridman_grid2d_merge	(	type(gridman_grid)	GRID,
		type(gridman_grid)	GRID1,
		type(gridman_grid)	GRID2,
		real(gridman_dp), intent(in)	TOL,
		integer, intent(out)	IERR
	)

Merge two 2D grids by connecting their boundary edges.

GRID2 is merged into GRID1 by connecting their boundary edges.

WARNING: the object GRID must not be equal to GRID1 or GRID2!

WARNING: The object GRID will be overwritten if already exists!

WARNING: the algorithm implemented at the moment assumes that edges of GRID1 and GRID2 which overlap with each over can be completely removed. That is, there are no "hanging tails" which do not belong to the intersection

Units of GRID are same as units of GRID1

Parameters

	grid	Resulting grid object
	grid1	First grid which stays intact
	grid2	Second grid which is merged into the first one
[in]	tol	Relative accuracy of the points coordinates

• If TOL is too large than the code can mistakenly take two different points for one point
• If TOL is too small then the code cannot recognise a point which is same in both grids

Recommended value TOL=1e-5. It might be necessary to increase or decrease TOL in each individual case.

Parameters

[out]

ierr
