# Granular Sheet shelf tool

Fills the surface of an object with densely packed grains and makes constraints to hold them together.

Fills the surface of an object with densely packed grains and makes constraints to hold them together, and is much denser than the Granular Solid. This provides resistance to bending, resulting in a stretch sheet. It is useful for simulating simple cloth, such as a blanket or drapes.

This tool can be thought of as a simple cloth solver. It results in cloth-like behavior because there are no collisions between particles since they are all right next to each other and constrained. An advantage of using this tool for simple cloth simulations is that itâ€™s very stable and faster in certain instances.

## Using Granular Sheet

1. Select the object to convert to a Granular Sheet.

2. Click the Granular Sheet tool on the Grains tab.

The following are a couple of examples of things you can use the Granular Sheet tool for.

For specific parameter information, see the POP Grains help.

# Grains tab

• Creates a grain object from a piece of geometry.

• Creates a grain object from a piece of geometry, with a clumpy wet look.

• Creates a patch of sand with a collision object which contains the sand.

• Fills an object with spheres and uses the Bullet solver to drive them.

• Takes each particle from your original simulation and replaces it with a cluster of new ones.

• Fills an object loosely with grains and creates constraints to hold it together into one object.

• Fills the surface of an object with densely packed grains and makes constraints to hold them together.

• Fills grains along the edges of polygons, creating a beaded wire effect.

• Allows grains to wake up and go to sleep based on the velocity of nearby particles.

• Activates particles near animated geometry.

• Slices a particle fluid across an arbitrary plane for distribution to a simulation farm.

• Slices a particle fluid using a set number of slicing planes evenly spaced along a certain direction.

• This tool sets up the networks of a simulated object so that it can be solved in parallel on multiple machines using HQueue.
