Dear Tian,

thank you very much for the reply and suggestion:

The number of critical points of each type:
(3,-3): 30, (3,-1): 31, (3,+1): 2, (3,+3): 0
Poincare-Hopf relationship verification: 30 - 31 + 2 - 0 = 1
Fine, Poincare-Hopf relationship is satisfied, all CPs may have been found

It is great that Multiwfn prints the Poincare-Hopf relationship after the calculation of the CPs, that's very handy!

Thank you!

Dear Paul,

I don't think there should be a CP, as the distance is long. Please check if Poincare-Hopf relationship has been satisfied, if yes, all CPs should have been found.

Best,

Tian

Dear Multiwfn community,

I am new to Multiwfn, hence my apologies if the question sounds naïve or obvious to some of you.

I am trying to obtain AIM analysis with Multiwfn based on some ORCA calculations, following the excellent tutorials I have no issue to obtain some nice results. However I am struggling to find a particular CP:

It seems to me that a CP between C22 and Au6 is missing, I tried to tweak the parameters but without yet success.

Can anyone help me?

Thank you in advance,
Paul
