As the copyright holder, the Foundation licenses OpenFOAM free and open source only, under the GNU general public licence (GPL). The GPL gives users the freedom to modify and redistribute the software and a guarantee of continued free use — as long as the terms of the GPL are adhered to. In particular, there are terms to the GPL that provide protection against exploitation by companies including OpenFOAM within non-free and/or closed source software products. First, when any modified version of the software is redistributed, the source code must also be made available by the distributor. Secondly, any modified version can only legally be distributed open source under the GPL , without limiting the rights on further redistribution. Software that links intimately enough to OpenFOAM has to be distributed under the GPL as well. Copyright statements on the software must remain intact.
