I am not verry familiar with OpenFOAM, but would like to learn more about it. This is just a question to point me in the right direction. I am doing some modeling of Plasma Flow control and will be modeling it as volumetric energy addition. Is there something in OpenFoam that I could use to add energy to a specified volume at specified times in the simulation? In FLUENT, I would use a UDF to accomplish this (I think) what would I look into to do it via OpenFOAM?
Thanks, Kevin |

Hi,
I'm not sure if you need the time dependent energy addition at a BC or in the flow field (a few more information would be helpful). In case of the BC, have a look at funkySetField and at the BC classes in OpenFoam. This should at least give you a clue how to implement the needed function yourself If your need it in the flow field, I guess you can add a term in the energy equation that does the trick. Best Regards, Christian |

Thanks for the feedback, I think OpenFOAM is what I want to use for this project. I have been setting up my system so that I can recompile parts of OpenFOAM that I edit. I did some experimentation and edited laplacianFoam to include a uniform heat source and it seems to work well. I followed another post of the forum. From what I understand I can use funkysetfeilds to get the shape of the source right, but how can I pulse the source in time? I will admit, I havent looked much into any of the set fields things, but I am just trying to think in advance.
Thanks, Kevin |
