B2000++ Data Structure
This chapter summarizes the B2000++ data structure hierarchy. As the MemCom dataset structure is flat, a hierarchy is obtained with the dataset naming conventions.

Mesh (Branch) Datasets
Finite Element Mesh
Required datasets describing the finite element mesh of any branch
<br>. These datasets must be defined for every branch referred to
by ADIR.
Branch description table describes the type of mesh, elements used, as well as other global information pertaining to the mesh |
|
Mesh node coordinates array |
|
Node attributes array. Contains node attributes for every node of mesh |
|
Element description (sparse) table. Contains, for every element in mesh, all element data, such as connectivity, material identifier, etc. |
Optional datasets describing the finite element mesh of any branch <br>. Applications will check if they are present.
