"\\Automagically Detect Compound Variables\: Checking this option will cause the plugin to try to guess that similarly named variables are the scalar components of an aggregate type such as a vector, tensor or array variable. The plugin will then automatically define expressions for these aggregate typed variables. Note that this is just a convenience to free users from having to define expressions manally within their VisIt session.\
\
\Material Count (-1=guess)\: Ordinarily, the plugin will determine the material count from the material convention nameschemes. However, if it is having trouble getting the correct count, you can specify it manually with this option. \
\Use Material Convention\: A few pre-defined conventions for handling mixed materials from Exodus files are supported. In addition, you can define your own custom conventions as well. For a custom convention, you must define the \namescheme\ that will produce the names of the scalar variables holding material volume fractions. Optionally, you can specify a \namescheme\ to produce the names of the scalar variables holding material-specific values given the name of a non-material-specific variable. For more information on nameschemes, please consult the description of DBMakeNamescheme in the \Silo user's manual\. The nameschemes used here are identical to those described in the Silo user's manual with one extension. The conversion specifier %V is used to denote the basename (non-material-specific) name of a set of scalar variables holding material specific values.\
\
The ALEGRA nameschemes for volume fraction and material specific variables are \"@%s@n?'&VOLFRC_%d&n&':'VOID_FRC':@\" and \"@%V_%d@n\".\
\
The CTH nameschemes are \"@%s@n?'&VOLM_%d&n&':'VOID_FRC':@\" and \"@%V_%d@n\".\
\
Finally, it is assumed materials are identified starting from one (1). The special material id of zero (0) is used to denote void."
