CFD BC setup

Hi,

 

is there a way to define the BCs for a CFD analysis in Hypermesh 13 or 14? I need to compare Abaqus, OpenFOAM and Acusolve, but I only know how to export the mesh to the corresponding file type. BCs → Components → CFD gives me a list of components, but I assume that I need material properties as well, which I don't know how to define as I can't find any option to create material or property definitions. Being able to define the BCs in HM would simplify my task greatly, as for now I need to set them up individually. Also, when I export the model to OpenFOAM the BC definition files are missing and I need to insert them manually, so a complete model setup would be really useful.

    you can define material properties using Abaqus user profile.For Open FOAM please check in online help.

    Hi

     

    thanks for your reply. Of course it's a good idea to mesh everything using the CFD profile and doing the rest using the Abaqus profile, that simplifies the task a bit. Concerning the OpenFOAM topic: I've already searched the online documents, but couldn't find anything useful other than general export routines. I might have overlooked something, I'd be glad if someone would point me to the right place. As far as I can tell, the description of BC setup seems to be done only in Acusolve and there seems to be no description on how to do that using the general CFD profile in Hypermesh. As I wrote earlier, for now only the mesh is exported to OpenFOAM files, but no BCs or material properties as they're not existent in HM. Is there a way to set up a complete model using the general CFD profile or at least a way to create dummy BC and property files containing correct component names that I could edit manually? If I define the BCs, materials etc in the Acusolve interface, exporting the model to OpenFOAM still does not create the required files (U, p and transportProperties).

    Currently, HyperMesh supports only creating/exporting mesh for OpenFOAM. We are planing to support more CFD solvers in the future.

    RIght now you will have to manually create those files for OpenFOAM using text editors.

    Too bad, but thank you anyway.
