TetGen Licensing FAQ
1) Q.: What are the licensing conditions for TetGen ?
TetGen is free software: you can redistribute it and/or modify it under the terms of the GNU Affero General Public License as published by the Free Software Foundation, either version 3 of the License (AGPLv3), or (at your option) any later version. A copy of the AGPLv3 is reproduced here. TetGen is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
2) Q.: Sorry, but under these conditions I will be unable to use TetGen. My company is selling the software it produces and makes a living from that. If we take the AGPL seriously, we would starve, or we cannot use TetGen.
If the terms and conditions of the AGPL v.3. would prevent you from using TetGen, please consider the option to obtain a commercial license for a fee for one of the versions 1.4 - 1.6.0 . These licenses are offered by the Weierstrass Institute for Applied Analysis and Stochastics (WIAS). As a rule, licenses are provided "as-is", unlimited in time for a one time fee. Please send corresponding requests to tetgen@wias-berlin.de. Please do not forget to include some description of your company and the realm of its activities.
3).Q.: How much is a commercial license then ?
Price quotes are provided upon request. Please do not hesitate to contact tetgen@wias-berlin.de for a quote.
4) Does the commercial licensing policy extend to new versions of TetGen ?
Details about the extension of this dual licensing scheme for future versions of TetGen will be announced in due time.
