FAQ - Hybrido

Can the Hybrido Domain be mixed with particle-based emitters?

Standard particle fluids and Hybrido fluids are completely different technologies. For that reason, both types can not interact with each other.

What is the GridFluidDomain?

This is the core node of the Hybrido technology. It is the place where the grid-based simulation takes place, and where the secondary effects (splash, foam and mist) are generated.

Do the "k" daemons affect the Hybrido domain?

Yes.

Does Hybrido support (variable) viscosity?

Of course.

What is the process to work with the GridFluidDomain and Splash?

• Create a Hybrido domain.
• Create or import an object for emitting particles.
• Create the Hybrido emitter and attach the object
• Create a force-based daemon,e.g. "Gravity.
• Simulate.
• Set the domain to "Cache" mode
• Add a "Splash" emitter, adjust its parameters, and simulate.

Why refuses the "Splash" emitter to create particles?

Please make sure that you have connected the "Splash" emitter to the Hybrido domain in the "Relationship Editor". The "Splash" emitter can be connected to any daemon too.

Why refuses the "Foam" emitter to create particles?

Please make sure that you have connected the "Foam" emitter to the Hybrido domain in the "Relationship Editor". Please do not connect the "Foam" emitter to a "Gravity" daemon, because the particles' position is calculated automatically by the Hybrido solver. If you simulate foam particles from cached splash particles, you can lower the substeps to 1 for the foam generation.

How can I speed up a Hybrido simulation?

1. Keep "Cell size" as big as possible and increase the number of particles instead. The particle counter per cell can be adjusted with the emitter's "Particle sampling" values.
2. Open the "Hybrido" tab under "Simulation Options" and decrease "MAX substeps".
3. Use the Command Line version instead of the GUI application
4. Activate the "Use Open CL GPU" checkbox in the "Hybrido" tab under "Simulation Options".

How can I use the PXY (proxy) format with Hybrido simulations?

This a general question for all particle-based emitters and Hybrido domains. This format is used to increase the velocity charge of particles when they are loaded from cache. If you want your previews to run faster, use PXY format and store the files locally. If there are PXY files selected in the "Export Central", previews will be created from this type.
