Mycelium Posted February 28, 2021 Share Posted February 28, 2021 (edited) Hi, I'm having some trouble getting the 'Vorticity' attribute to show up in my cached sim: I've already made sure to check the 'Keep Attributes' for the fluidcompress node with 'vorticity' previously also checked 'Transfer Attributes' with 'vorticity' Also tried recaching everything again, but it still doesn't show up. Will appreciate any help I can get, thanks! Edited February 28, 2021 by Mycelium Quote Link to comment Share on other sites More sharing options...
Atom Posted February 28, 2021 Share Posted February 28, 2021 (edited) Rewind and recache? It seems to work when I add it to the attached simulation. ap_flip_viscosity_by_attribute.hiplc Here is a microsolver version here.

I tried rewinding and recaching, but it doesn't seem to work still. I'll take a look at your file. Also here's my hip file as well if it helps.

ryew Posted February 28, 2021 Share Posted February 28, 2021 Using your latest uploaded file, I do see the vorticity attribute after unpacking at the end - I've changed nothing in your file aside from particle separation to make it easier on my machine.

Hmm strange. I just recached it at a lower resolution (lower particle separation) the vorticity attributes showed up, so I thought it was just a one-off thing, so I increased the resolution again (higher particle separation), recached and the vorticity attributes DISSAPEARED again! It seems to disappear when I increase resolution for some reason. This is so frustrating.. Edit: Okay so I figured out that the vorticity attribute doesn't show up on the first frame... I wish I realised that sooner.. Edited March 1, 2021 by Mycelium Quote Link to comment Share on other sites More sharing options...
Atom Posted March 1, 2021 Share Posted March 1, 2021 It seems to work for me. I can see vorticity on the final surface even without unpacking. Perhaps you have cached something along the way without vorticity? Try removing all Load From Disk check boxes and sim a few frames..?
