Issue with ConcaveHullMesh

I'm having trouble getting the function ConcaveHullMesh to work. As far as I can make out from what I can see in my User Portal, I'm running the latest version of Mathematica (13.0.1.0). Even the two Basic examples in the Online Documentation Center don't work: when I evaluate these expressions I just get back the input. One possibility is that the latest version of Mathematica isn't appearing in my User Portal. I say this because the Documentation Centre has a page titled Summary of New Features in 13.1. But, as mentioned above, I'm running 13.0.1.0 which must surely be an earlier version? I'm somewhat confused and any advice/suggestions would be much appreciated.

Looks like 13.1 is officially released. The download is available on the user portal.

You can evaluate $Version to check which version you are running.

Agreed, That was one of the first things I checked. V 13.0.1.0. The issue is, there seems to be a V 13.1. But I don’t see that version available for download in my user portal. And the function ConcaveHullMesh doesn’t appear to work as described in the online documentation.

13.1 is not out yet. ( https://www.wolfram.com/mathematica/quick-revision-history.html ) It will come soon though as the documentation is already partially online. However in my V13 ConcaveHullMesh also doesn't to work. So probably there is some bug. Hold on tight for 13.1?

Thanks Sander. I think you’re right. It looks like the documentation has gotten ahead of the software. I’ve not noticed this happen before. But presumably it means the release of 13.1 is imminent.

I knew it was imminent, but didn't know it was that imminent. Perhaps try ConcaveHullMesh in 13.1? The documentation example works for me fine in 13.1 beta. I didn't have time to get 13.1 final yet…

Thanks Rohit, that's great news.
