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.
