Milad.Savar Posted August 7 Share Posted August 7 Hi everyone . I'm looking for a way to simulate two different objects in a single simulation. The idea is that one object is a FLIP water simulation, and the other is a collision object that gradually dissolves (melts). For example, when hot water drips onto an ice block, the ice melts over time. I don't want to run two separate simulations . i create a simple pseudo setup to explain the idea . Thanks!

Librarian Posted August 12 Share Posted August 12 (edited) @Milad.Savar do you have reference on that ...??? in real life some footage , What happens When HOT Water (DROPLET) hit ICE??? i found something on Youtube ?? did you check those videos?? maybe Use Sop Solver !!

Milad.Savar Posted August 13 Author Share Posted August 13 Hey Tesan, thanks for your advice! Actually, I haven't followed any specific reference. My point is to update the collision every frame, while at the same time, the particles dissolve the collider more as they hit it. It's kind of like a Growth Solver, but here we have a continuous feedback loop between the FLIP and the ice collision. The FLIP collision ice → the ice changes/dissolves → the collision gets updated → and the FLIP reacts to the new collision. Quote Link to comment Share on other sites More sharing options...
Milad.Savar Posted August 13 Author Share Posted August 13 i have did someting with Gas Collision - but not working - i know someting is wrong ;D Melt Ice_v04.hip Quote Link to comment Share on other sites More sharing options...
Librarian Posted August 13 Share Posted August 13 try this logic maybe ..check also DOP Geometry spreadsheet @Milad.Savar gascollisiondetectdop-make-volume-data.hipnc Quote Link to comment Share on other sites More sharing options...
Librarian Posted August 13 Share Posted August 13 @Milad.Savar and files to check other solution and combine to fluid-solver i think is useful .. and check examples from FuatYueksel_Siggraph gasparticletofieldgh01.hipnc 1 Quote Link to comment Share on other sites More sharing options...
