MATLAB function for importing PCB tracks

If you deal with PCB tracks with COMSOL the problems are:
- use CAD import (or lievlink). Most of PCB design softwares have poors CAD export capabilities.
- use ODB(X)++ import. Most of PCB design softwares can't export ODB(X)++.
In order to solve this, I write a MATLAB function to convert Gerber PCB data to ODB(X)++ for COMSOL import.
Gerber is really a standard (all PCB software can handle this), then you can import the resulting geometry in COMSOL.
The workflow is the following:
1) Design your PCB with your favorite software, export the layout as GERBER files
2) Use the MATLAB function to convert the GERBER into ODB(X)++ files
3) Import the geometry with COMSOL (4.1 or 4.2)
It has worked without any problem for a PCB coil (with Altium Designer Summer 09 and COMSOL 4.2a).
You can find the code in the MATLAB file exchange with:
- the MATLAB code for doing the conversion
- an example geometry (a PCB coil)
- the COMSOL file with the imported geometry (PCB coil with a simple electric current physics).
The function should works with any simple geometry (two layers, tracks and vias).
