Common Options
==============

.. _fluid-animated-mesh:

Animated Mesh/Export
--------------------

Click this button if the network is animated (eg . Deformed by an armature, shape keys, or lattice).
It can become very slow and is not necessary if the network's position and rotation are animated.
(i.e. only object transformations).


.. _fluid-initialization:

Volume Initialization Type
--------------------------

A common option among the different fluid types is *Volume Initialization*.

Volume
   The inside of the object is initialized as fluid all. This works only if the mesh is closed.
Shell
   It is initialized as a thin fluid layer of the surface of the mesh. This can also be used if the mesh is open.
Both
   It is a state, such as the sum of the Volume and Shell. This also must be a closed mesh.
