Other data for user interface, graphical modeling and rendering

VisualFEA file contains not only the data necessary for finite element analysis but also other data related to user interface, graphical modeling, rendering and etc. These data are not directly used in finite element processing, but are essential to maintaining and managing the source of data in graphically interactive work environment. These data can be classified into 3 types: geometric data, source of assignment data, and input and view control data. The geometric data are graphical data for hierarchical construction of finite element model, and consist of 

The source of assignment data implies the native data used in interactive work environment. The actual data used in processing are extracted from this source. 

The load condition data are used for interactive assignment of load conditions, and are the source of equivalent nodal force data which is actually used infinite element analysis. Likewise, heat boundary condition data are the source of equivalent nodal heat data. The input and view control data are related to viewing transformation, rendering and input environment of graphical models. 

There are also the kind of data which serve for the source of interactive graphical modeling as well as for direct use in finite element processing: 

The data described in this section are also important for interface with other CAD or graphical modeling software. Data may be imported from such software for further processing by VisualFEA. Or, VisualFEA data may be exported for use in other software.
