Pyro, Steam

[Khikmatillo]

Hi, I am doing a steam effect from kettle,  kettle model is real size, first one is that pyro solver does not detect a collision, and the second one isthat  there are two pictures, How can I achieve this result? please help,

You need more solution for the smoke sim and probably need to create a better collider. Can't hep much more without seeing the file and the collision mesh.

You can also apply some post sim volume sharpening after you fix the above issues @Atom mentioned.

Ok, Thank you Yunus, I will

Hi Khikmatillo

Firstly you will need to close up you geometry for the sdf to work well in the sim, Try using a polyfill on the geo before turning it into sdf, or giving it some thickness on the walls of the kettle.

Also you don't need the collision geometry to be this precise, In you current setup it is set to be 10x more precise than you simulation, try setting it to a bigger value ( e.g. if your pyro sim is .01 (voxel size) the most precise you will need your collider sdf to be is .01, but feel free to set it to a bigger value like .1 since collision in your case doesn't need to be all that heavy to compute to get the good result )

This is my first post here, so I hope it helps

Hi, Lazar Lukic,

Thank you for reply, I almost got the result
