smoke solver

[Hello world]

Hi I did a sim using smoke solver.But i dont find option to add details like noise,turbulence and so on.How can we add details,do we need to use volume vop?

Are you using the Smoke Solver or the Pyro Solver? I am assuming you are using the Smoke Solver.

If you are, switch it out for the Pyro Solver as it has most of the Gas shaping micro-solvers built in and is accessible in the Shape tab. The Pyro Solver is just a wrapper on top of the Smoke Solver.

 

If you want to work with the Smoke Solver, you need to wire up the various shaping micro-solvers yourself. Nothing wrong with that btw. You would wire them in to the Velocity Update input (use MMB on each input to see the label or it's the second green input from the left). Generally you wire in a Merge DOP and then wire the various Gas shaping micro-solvers.

 

The standard shaping type DOP shaping micro-solvers are:

Gas Turbulence DOP

Gas Shred DOP

Gas Vortex Confinement DOP

Gas Disturbance DOP

 

 

If you want to add shaping to the resultant simulation afterwards, you can run a Gas Upres simulation, or you can add detail using SOPs (look at the Cloud Noise SOP as an example of how to add interesting detail to your volumes).
