Dear GeoPDEs users,
I am happy to announce the release of a new GeoPDEs package that
supports T-splines. This new package offers the possibility to import a
T-spline geometry designed with the Autodesk T-spline plug-in for
Rhino3D, and saved in the new file format available in the plug-in,
which is based on Bezier extraction. As usual, the package can be
downloaded from the GeoPDEs webpage:
The new package includes some simple examples, to show how the two main
data structures of GeoPDEs, msh and space, can be computed from Bezier
extraction. Other features of GeoPDEs, such as exporting the results to
VTK format or computing the error in L2 and H1 norm, have been also
adapted to Bezier extraction.
For now the T-spline capability of GeoPDEs is restricted to planar
surfaces, and all the examples are written for the scalar Laplacian. If
you are interested in developing (and sharing) further extensions of the
package, feel free to contact me for help.
I attach below an e-mail from Mike Scott with more information about the
Autodesk T-spline plug-in for Rhino3d, and a link to the beta-version.
Dear IGA Researchers,
In an effort to make T-spline-based IGA technology more accessible to the academic community we have attached a link to the new beta-version of the IGA-capable Autodesk T-spline plugin for Rhino3d. Included are free 32 and 64-bit installers for the plugin as well as a write-up of the new IGA-related commands and an introduction to the underlying technology. We have also included a directory of geometries which have appeared in past T-spline/IGA papers and which you can use to explore the functionality of the plugin.
Note that all Autodesk products are free to academic researchers. This means that as the plugin moves from beta to release it will remain free. Rhino however is not free but has very reasonable academic pricing.
The next release of the T-spline plugin for Rhino will be happening in the next few weeks so check tsplines.com in the coming weeks to get the official release.
I hope this proves helpful in your own IGA-related research and we look forward to your feedback as we continue to improve and expand these capabilities.
