|Summary||0003633: Maybe an error in documentation?|
Can you check whether in the documentation:
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?
|Tags||No tags attached.|
||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:
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:
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.
