Ah, sorry! Yes, the programmer's guide is incorrect.

error in wikipedia
Hey, the following eq from wikipedia posted higher up in this thread has a typo:
"When I look up for the definition of the divergence of a tensor field, on wikipedia for instance this is http://www.cfd-online.com/Forums/vbL...3f1e0b73-1.gif " and further it is not consistent with the other parts of this thread - it should be Tik not Tki . Also there are some typos in the matrices you put up, but they are not too hard to figure out. And the overall thrust of the thread is correct. |

FYI: I've consolidated this information here: http://openfoamwiki.net/index.php/Op...s_Guide_Errata
Feel free to add to this wiki page. By the way, the issue reported on this thread has already been fixed on the Programmer's Guide since OpenFOAM 2.2.0, at least from what I could find. |

I found several books and papers about tensors. Most of them are showing this:
Attachment 48139 and Attachment 48140 I have implemented an algorithm in python to compute the tensor divergence to a 3d tensor field. I am not sure if my implementation is correct. Does any one have some tensor field and its divergence to compare? It could be a .txt, .mat, .py, etc. Thank you |
