Axiom is a sparse, GPU accelerated volumetric fluid solver for computer graphics and visual effects. It’s key feature is the custom OpenCL volume data structure thats lets sparse simulations run on a GPU.
ah ok, didn`t know that. There is a checkbox in the sparse solver? Nevertheless, I played with axiom for like 5 Minutes. It feels amazing. Super fast and user friendly!
Having issues running with Linux. Looks like the solver isn't running with 18.0.499.I am just getting the source result output from the Axiom Solver node. Is anyone else having the same issue?
have you copied the dso files to your Houdini user folder?

Yes I did. I tried them in the Houdini 18 folder inside documents and the Houdini 18 folder inside program files. Neither seemed to work. I was thinking it was perhaps because my otls are in a separate folder inside the preferences folder named otls. But it didn’t work with the axiom otl in the base preferences folder either.
All of the Files should Go to your User Folder under Documents. What i usually do against this Kind of Problems is to rename the User folder to Houdini.18.XXX or whatever. Then restart Houdini. It will create a new User folder for you. Copy the axiom Otl and dlo Folders to this new User folder and try it again. Maybe its conflicting with something else in your old User folder.

Hey thanks, that does work. It’s just very not ideal because I have a bunch of other stuff installed. Still trying to troubleshoot how to make it work with my preference folder that’s full of stuff. Because I have a folder called ‘otls’ which Houdini recognizes, if I put the axiom otl into the base preferences folder Houdini doesn’t see it. And if it’s in the otl folder, it can’t find the dll it seems, I believe that’s what the issue might be.
Hey Jonathan, off topic package syntax question here: Can you elaborate the naming you just put in there with the “~1”? Does that evaluate into the first matching folder with “DOCUME” like tabbing in the shell on a linux machine? I was curious as the Houdini textport evaluates paths similarly. Just ever confused using windows and having unix syntax in some places for Houdini.
On that account, I believe the new 18.5 minimal solver (using a newer, more efficient version of VDBs) is similar, but Axiom is more production capable with the sparsity and ability to switch with the same algorythms, as the new minimal solver does not support that (yet). Also with the Houdini minimal solver, I've experienced the promised switch from GPU to CPU NOT to be without change, so it does not match exactly, which is a shame - but I might be wrong. Concerning that, does anyone have experience with Axiom switching for final highres export?

i cant for the life of me get this to work, I have copied the contents of the Axiom folders and followed the instructions exactly. however, upon restarting Houdini, Axiom does not show up? any idea why that may be? ( i have created Packages folder too)
