Detailed Description

An XMDF file consists of one or more groups. Each group represents an unstructured mesh (or set of scattered data points), a structured grid (either Cartesian or curvilinear), a set of cross-sections, or a group of geometric paths in space (such as particle paths). Each of these groups may include one or more subgroups with functional data sets for the group. Also associated with each group, the XMDF file stores a sub group that contains a set of variables that define the properties of the group. Each group type has a set of required properties that must be specified in order to define the group. Additional properties can be added to the group for specific applications. Properties can include a single value for the group (such as a type of structured grid), or a value for each node, cell or element in the group (such as a node id or name).
