New page

This page contains a number of example scripts which show off some of the more advanced classes used to achieve specific tasks within TexGen.

=== Geometry Solver ===

The theory behind the geometry solver is described in a paper submitted to "The First World Conference on 3D Fabrics and Their Applications" held in Manchester on the 10-11th of April 2008 titled "...". A longer version of this will shortly be submitted as a journal paper.

		+	===Correction of Small Intersections===
		+
		+	This script enables small intersections to be corrected automatically. It is the method which is used when correcting intersections in the ABAQUS Dry Fibre File export function and is based on the volume mesh (as drawn by the Rendering->Render Textile Volume option). It is intended to remove small intersections which may cause problems when running simulations and makes small adjustments to the local cross-sections of the yarn to remove these. Intersections which are greater than the depth of the outside volume element will not be corrected. In these cases correction to the yarn path and cross-sections specified are probably more appropriate.
		+
		+	<pre>
		+	# Correct small intersections in textile (intersections greater than one volume mesh element in depth will not be corrected)
		+
		+	Tolerance = 0.0000001
		+	# Get the current textile - pass name as parameter if more than one textile loaded
		+	Textile = GetTextile()
		+	# Set up vector of yarn volume meshes
		+	YarnMeshes = MeshVector()
		+	# Create the interference correction class object
		+	AdjustMesh = CAdjustMeshInterference()
		+	# Fill the YarnMeshes vector with the individual yarn volume meshes for the textile
		+	AdjustMesh.CreateVolumeMeshes(Textile, YarnMeshes)
		+	# Correct the intersections in the YarnMeshes
		+	AdjustMesh.AdjustMesh( Textile, YarnMeshes, Tolerance )
		+	# Adjust the textile cross-sections to reflect the corrections calculated in the previous command
		+	AdjustMesh.AdjustSectionMeshes( Textile, YarnMeshes )
