Hi there,
I would like to implement a Source Term. The trouble is that it is calculated thanks to a lot of variables and the BC of that source term is not specified.I am a bit tempted to put a zerogradient everywhere when I implement it.Can anybody tell me what I should do?How can I specify the BC of that source term? Best Regards. |

Hi sambatra,
why do you need BC's for a source term? The choice of BC's is only important, if you want to solve an equation for that field. If it is only a source in an equation for another field you can use the default calculated BC. (BTW the boundaryField shouldn't be used when having a volumetric source. In fact it should make no difference which kind of BC you use.) Regards, Stefan |

Hi Hebert,
Thank you so much for your information! the reason I was asking that question was that the sources are to be relaxed so I guess creating field is required! BR, |
