CastNet: modeling and meshing tool for OpenFOAM
Dear OpenFOAM user,

I would like to inform about the modelling and meshing tool CastNet for OpenFOAM. CastNet is based on CAD-preparation and advanced CFD-meshing technology of Simmetrix Inc., which is used in background by various commercial CFD-grid generators or CFD-systems. Based on this technology we built an OpenFOAM modeling environment, allowing native OpenFOAM export and defining complete OpenFOAM cases for often used solvers. This includes GUI setups for solvers, flow properties, physical models and geometry associated definition of boundary conditions, initial conditions, face zones (e.g. baffle faces) or cell zones (e.g. porous regions). Additionally case adapted scripts are exported with the mesh organizing the case setup and solving.
More information can be found on our websites (English/German) or just contact me.

Best regards

Hi ulli,

I'm also using CastNet and can only recommend it to all other foamers. The created meshes are of good quality and the environment of the GUI is very friendly. The amount of modification possibilities is very huge. although it is an automatic mesher one can manually give enough boundary conditions to make the mesh look like desired. The compatibility to OpenFOAM is very good.

I am very satisfied with this tool. And the price is quite okay, compared with othe commercial meshing tools.

Best regards.

Hi Uli,

Could you please give me the english website for the link. It had some error when I tried to access.

Hi Robert,
sorry for the dead link. Here youíll find the information ( We have a new version of CastNet meanwhile supporting more solvers and also an additional GUI to control the OpenFOAM run. You will find more information about this on our news-side:
Best regards

Hi Uli,

Thanks very much for that.

Just wondering is this software considered as open source??If not can I get a trial version first??

Thanks very much.

Kind Regards,

Hi Robert,
unfortunately, we can not provide CastNet as open source. CastNet is based on a commercial meshing technology, so we have to pay license fees ourselves for every CastNet license. There are some tools (e.g. our rungui) where we probably will provide a free version for all OpenFOAM users. Here we donít have to pay license fees.

Of course you can test CastNet one month free of charge.
Best regards

Where to get castNet evaluation version for OpenFOam


I am working on a case which has compressible flow in Porous media along with Heat Transfer. I am looking for a tool to set up my case in OpenFoam-1.7.x. Can somebody reccomend from his experience about CastNet for OpenFoam, How it would be to setup my case. I have my mesh prepared and want to use it for other preprosiing thinng. But I would like to have a evaluation version first. Please some body tell me how to get it.
