TexGen has been used by the Nottingham team as the basis of models for a variety of properties, including textile mechanics, permeability and composite mechanical behaviour. A summary of our work involving TexGen can be found on the [[TexGen Applications]] page and a list of publications using TexGen can be found on the [[Publications]] page. Please also visit the [http://www.nottingham.ac.uk/research/groups/composites-research-group/research/textile-composites/textile-composites.aspx University of Nottingham Textile Composites Research] website for more details about our research group. On this website you will find all the information necessary to get started with TexGen by using the sidebar for navigation. Please leave a message on the [http://texgen.sourceforge.net/phpBB3/index.php TexGen forum] if you find TexGen to be a useful tool. We are very interested to hear about research conducted with TexGen. The [http://texgen.sourceforge.net/phpBB3/index.php forum] is also the place to ask questions, make comments and generally discuss about TexGen with other users. Specific bug reports, feature requests and patches are always welcome and should be directed to the [http://sourceforge.net/tracker/?group_id=181000 sourceforge trackers]. == News == ===TexGen 3.10.0 Released! === Version 3.10.0 has been released. This contains a Rotate Textile option which can be used in conjunction with the Layer Textile option to create laminates with different textile orientations. There are new options to import weave patterns and then create pattern drafts from certain types of weave patterns. There has been some code optimisation to speed up the functions which calculate volume fraction and yarn orientations in the export functions. There are various other small changes and bugfixes. A list of changes can be found [https://sourceforge.net/projects/texgen/files//texgen/3.10.0/README/view here] <small>18:00, 13 December 2017 (GMT)</small> ===TexGen Survey === The latest version of TexGen (3.9.0) included an invitation to complete a survey on exit from the program. This takes just a few minutes and can be found [https://nottingham.limequery.com/728617?lang=en here]. If you are a TexGen user we would be grateful if you could find the time to complete this. The information in the survey is crucial to us as it will help us to put together the case for continued funding of the TexGen project which, for the most part, is supported by UK Research Council funding. Many thanks for your help! ===TexGen 3.9.0 Released! === Version 3.9.0 has been released. This contains functions to create a mesh of the centre plane of yarns using quad elements and functions to find the point on a yarn surface which is closest to a specified point. On exit from the program a dialog is triggered which points the user to an online survey. This is entirely optional but information about usage and benefit from using the software will help us to make the case with research councils to continue funding the project. This will enable us to continue its development and to keep it as free software. There are various other small changes and bugfixes. A list of changes can be found [https://sourceforge.net/projects/texgen/files//texgen/3.9.0/README/view here] <small>13:15, 14 February 2017 (GMT)</small> ===TexGen 3.8.2 Released! === Version 3.8.2 has been released. This contains functions to calculate fibre volume fractions of specified domains (unit cells if these correspond) and yarns. Functionality has been added to allow an angle to be specified at a node so that a cross-section can be angled relative to the yarn tangent. Creation of pattern draft for layer-to-layer textiles. Added option to wizards to select whether or not 10% is added to height of default domain. Windows installation files are available with Python27 to provide compatibility if calling TexGen scripts from within Abaqus 6.14. There seem to be issues on some machines with the Python27 bundled versions. If Python27 is required install Python from here https://www.python.org/downloads/ and then use any of the Python27 files. There are various other small changes and bugfixes. A list of changes can be found [https://sourceforge.net/projects/texgen/files//texgen/3.8.2/README/view here] <small>12:11, 19 January 2016 (GMT)</small> ===TexGen 3.8.0 Released! === Version 3.8.0 has been released. This contains the addition of a maximum nesting function to layered textiles.

The Window installation files now use Python 2.6 thus giving compatibility with recent versions of ABAQUS. There are various other small changes and bugfixes.
