exportDfn2geo: dfn to gmsh .geo file generation

In mathphysmx/gmshR: An R package to export to .geo gmsh format

Description

dfn to gmsh .geo file generation

Usage

exportDfn2geo(dfn, bdry, cl, file)

Arguments

dfn	data frame of line segments ends coordinates.
bdry	2-columns table (data.frame, matrix, array). The first column are the x coordinates and the 2nd column the y coordinates of the open polygon.
cl	cl Numeric scalar. Characteristic length of gmsh. It tunes up the meshing.
file	The name of the exported .geo file.

Details

To mesh the .geo files in the examples, go to the <file> directory, and run in the terminal gmsh -2 <file>. To view run in the terminal gmsh -2 <file>.geo <file>.msh.

Value

A file named <file>.

Examples

# Example 1
bdry <- cbind(x = c(1,6,6,0), y = c(1,0,3, 3))
data(dfn)
exportDfn2geo(dfn, bdry, cl = 0.1, file = 'dfn.geo')

# Example 2
data(synthDFN)
print(min(synthDFN$lengthCm))
bdry <- cbind(x = c(-1,401, 401, -1),
      y = c(-1,-1,  401, 401))
exportDfn2geo(dfn = synthDFN, bdry,
	cl = min(synthDFN$lengthCm), file = 'newDfn.geo')
