This check box determines whether or not the domain is initialized based on its own settings or based on global initialization settings. When this check box is selected, an interface that is essentially the same as that for global initialization is displayed. Any initialization values defined on a per-domain basis will override values defined at the global level. For details, see Global Settings and Fluid Settings Tabs. After specifying and applying domain initialization, an entry called Initialization is listed in the tree view under the applicable domain.
