I appreciate very much for your suggestion and solution to that issue.
- I am curious to find out the source of the affine connection containing two upper indices, which is unusual. :)
- I am not sure in which stage I have to apply the "ImplodedTensorValues" in xTras. I tried
ImplodedTensorValues[CD, LHS2, BdS]
ImplodedTensorValues[CD, ChristoffelCDPDBdS[\[Alpha], \[Mu], -\[Nu]], BdS]
None of those works. LHS2 is a vector quantity. Would you kindly provide some more suggestion in implementing it?
Thanks and Regards, Purnendu
