LoopTree Module

This module provides a conducting surface model for gANTlab using RWG base functions in loop-tree decomposition.



Matrix

The parameters are:

OFF file
surface OFF file
---
mesh unit metric of data file
m
center point x
x offset
m
center point y
y offset
m
center point z
z offset
m
theta
rotation angle theta
°
phi

RHS

The parameters of the excitation are:

no. of I sources
no. of current excitation points 1

And for every current source n:

n:pos x
x position of the excitation point m
n:pos y
y position of the excitation point m
n:pos z
z position of the excitation point m
n:abs(I)
amplitude of the excitation current
A
n:arg(I)
phase of the excitation current
°

The excitation takes place at the nearest node of the surface mesh.




Extract

The parameters are:

J VECT file
file name for current density at triangle center in VECT format
---
no. of J probes
number of probe points for surface current density 1
no. of E probes
number of probe points for electric field strength 1
no. of U probes
number of probe lines for voltage 1

So there are for every J or E probe n:

n:point x
x coordinate of probe point m
n:point y
y coordinate of probe point m
n:point z
z coordinate of probe point m

and for every voltage probing line n:

n:start point x
x coordinate of integration start m
n:start point y
y coordinate of integration start m
n:start point z
z coordinate of integration start m
n:end point x
x coordinate of integration end m
n:end point y
y coordinate of integration end m
n:end point z
z coordinate of integration end m

The voltage integration includes the internal module contributions only, the other probings the external ones via AIM grid also.
