The geometry file (or script) and the newFASANT project are included whenever the considered cases are distributable.
The script shown in next figure is included as “GTD-Coupling.nfs”.
#
# newFASANT script file
#
# Creates the geometry considered in "newFASANT - GTD - Coupling" example
# that has a box with its base centred at the origin and a rectangular hole
# and two cylinders at each side along the Y axis.
# The geometry has the following specifications:
# BoxCenterX: X coordinate of the base box centre
# BoxCenterY: Y coordinate of the base box centre
# Heigth: height of the box and cylinders, in Z dimension
# BoxWidth: Width of the box, in Y dimension
# BoxDepth: Depth of the box, in X dimension
# HoleCenterY: Y coordinate where the box hole is centred
# HoleCenterZ: lower Z coordinate of the box hole
# HoleEdge: Size edge of the box hole, in Y and Z dimensions
# R1: Radius of the thinnest cylinder, in XY dimensions
# R2: Radius of the width cylinder, in XY dimensions
# t: Auxiliary parameter to parametrize the hole Y coordinate
# and the cylinders radii
#
# Parameters with fixed values
#
