Using Collide with Objects

Overview ¶

The shelf tool converts its geometry into appropriate volumes, then imports them into the DOP network using a Volume Source node.

Note

As of Houdini 14, the recommended way of setting up collision objects for fluid simulations is by using Static Object or Deforming Object shelf tools under the Collisions tab.
