The Axiom solver won't show up inside DOPs, just in SOPs and you just need the velocity from the solver to advect. So just use the Axiom to create your sim and as Cyte mentioned then create a pop network and use the pop advect volume node.
Wow!! That sounds so simple and effective! I am not in front of my laptop right now. But really man!! Why was I overthinking? Life can be so simple sometimes. Just one SOP and one DOP! Boom. Definitely gonna try and post my results!! Thanks a lot @sepu and @CYTE!
CYTE simply add the axiom solver via sop this way:
Thanks a lot. That worked! I don't understand the principle behind this. Even though same stuff is being transfererred in the second node of DOP to do the simulation, why does choosing 'SOP' option work instead of the 'second context geometry'?
CYTE You cant simply blast an vdb like that. it is empty afterwards. check it.
Where do I check? What exactly is empty afterwards? The vdbfrompolygons node remains same.
