The MpCCI 4.x adapter for OpenFOAM has been developed by Fraunhofer SCAI. Those parts of the OpenFOAM adapter which have integrated parts of the OpenFOAM code - and only those parts - will be provided as cost-free and open-source modules. You still need to purchase a license token to activate the OpenFOAM to MpCCI interface.
The MpCCI-OpenFOAM adapter modules are distributed in source code. These sources need to be compiled at the end-user site. The compiled parts plus some additional binary software libraries from the MpCCI package have to be linked to the OpenFOAM versions.
Please note that the MpCCI-OpenFOAM adapter is an autonomous software package. It does not contain the MpCCI software which has to be licensed separately. Whereas the MpCCI-OpenFOAM adapter interacts with OpenFOAM, the coupling server in MpCCI CouplingEnvironment itself merely communicates via sockets with the MpCCI-OpenFOAM adapter.
