calculates vertex list and facet list for a wire-yarn
Description
This function calculates a 'bent wire style object' that is called yarn. The function uses mainly VLFLbar2P. It is also a good example how to design bars, and later to remove the planes at the beginning and the end for concatenating different segments.

Syntax
[VL,FL]=VLFLyarn(l,n,ld,b,h,s,u)
Input Parameter
l: | | length of the yarn in x-direction |
n: | | number of notches (1 is up, 2 us up and down, if u=1) |
ld: | | lenght of the notches (half at the begining and end) |
b: | | Thickness of the wire-yarn in z-Axis |
h: | | Thickness of the wire-yarn in y-Axis |
s: | | Additional Slot Distance beside h/2 (required depending on the crossing wires) can be negative |
u: | | direction of notches (1 starts in +y-direction, -1 starts in -y direction) |
Output Parameter
VL: | | Vertex list of the wire-yarn |
FL: | | Facet list of the wire-yarn |
Examples
Simple wire-yarn:
[VL,FL]=VLFLyarn (100,5,4,1,1,1,-1);
