Houdini 13.0 Shelf tools

Tank simulation

Wave Tank

Fills the whole tank with FLIP Particles. Simulation occurs throughout the whole tank.

Splash Tank

Only creates a thin layer of FLIP particles at the ocean surface. Simulation only occurs above the ocean surface (only splashes). Everything below thin layer is deleted and rebuilt on every frame.

Wave Layer Tank

Creates a layer of FLIP particles on the ocean surface. The layer of FLIP particles is sitting on a collision object that is more or less the shape of the ocean. Simulation only occurs in the top layer of the ocean surface.

Beach Tank

Fills the whole tank with FLIP Particles, minus the terrain object. Simulation occurs throughout the whole tank.

Flat Tank

Fills the whole tank with FLIP Particles. Simulation occurs throughout the whole tank.

Waves

Wave Tank

Only has the initial wave setup. After the first frame, the ocean will move around and lose energy, until it eventually settles or something else disturbs the fluid.

Splash Tank

Pulls in velocities from the ocean spectrum node to create a constant wave simulation.

Wave Layer Tank

Pulls in velocities from the ocean spectrum node to create a constant wave simulation.

Beach Tank

Pulls in velocities from the ocean spectrum node to create directional waves across the length of the tank.

Flat Tank

Does not start with any waves, but will react to objects that disturb it.

Tracking

Wave Tank

Can follow moving objects.

Splash Tank

Can follow moving objects.

Wave Layer Tank

Can follow moving objects.

Beach Tank

Can not follow moving objects.

Flat Tank

Can follow moving objects.

When it is useful

Wave Tank

Useful for short ocean simulations where you don’t need to control the shape or movement of the ocean.

Splash Tank

Useful for static objects such as rocks that will create splashes.

Wave Layer Tank

Useful for shallow objects moving through the water, like a boat.

Beach Tank

Useful for simulating waves breaking on a beach or other shallow water terrain.

Flat Tank

Useful for any calm water simulations that don’t require waves, or for simulations that are going to displace a lot of water, such as a whale moving around and jumping out of the water.
