Summary | 0003633: Maybe an error in documentation? | ||||
Description | Hello, Can you check whether in the documentation: https://cfd.direct/openfoam/tensor-mathematics/ in "5.5 Useful tensor identities", the last identity: (nabla x a) x a = a dot (nabla a) - nabla (a dot a) is correctly written because in two other places I saw that there is some 1/2, which might be next to the second term on the right hand side of the equation? Best regards, Stefan Bošković | ||||

Also, when I used that identity, I got the results which might be two times greater than expected (maybe because of the missing 1/2). |
|
> in two other places I saw that there is some 1/2 In which places? Can you provide a reference? |

Equation (4.63) in: https://books.google.com/books?id=WIRcB6VJ0mYC&pg=PA182 but I'm not sure how correct is the list of equations because it seams to me that the author wrote as if: (u dot nabla) v = u dot nabla v which might not be correct. In text below equation (4.9) in: https://books.google.com/books?id=8QNfImKvQBsC&pg=PA112 |
|
Thanks, that is correct. The 1/2 was missing. A correction is uploaded but it can take around 24 hours for file caches to update. I will note the update once that happens. |
|
It is updated - you may need to clear cache. Thanks. |
