MED Objects

MED Object is a specific twofold data structure with consists of Mesh Data and Physical Data.

It is not possible to create and edit MED Objects in the Post-Pro module. You can only import a MED object from Salome MED module or from a MED file.

MED Objects can be visualized and explored with various types of 3D presentations.

Post-Pro visualization engine bases on VTK and OpenGL technologies, which provide useful tools for Management of presentations.

As it can be seen, the description of a MED Object is written in a tree-like form, containing three main folders: Families, Groups, and Fields.

Families

A Family is a user-defined submesh composed of cells of a definite type - Nodes, Edges, Faces or Cells. The presentation created on the basis of a particular family will be composed of geometrical elements, corresponding to the type of cells of this family.

Type of cells (entities) of the family Geometrical element
Nodes Points
Edges Segments
Faces Triangles, quadrangles
Cells Any

Table of correspondence

In the Families folder all families of the mesh are put into subfolders defining the type of cells of the mesh: onNodes, onEdges, onFaces, onCells.
The subfolders also represent submeshes of the mesh, which are composed of all cells of the mesh of this type.


Groups

Groups combine families independently on the type of cells, of which they are composed.


Fields

Fields represent the results of calculations (scalar or vector values), grouped under one physical concept.
These values are applied to the cells of a definite submesh, which is indicated in the Object Browser in the subfolder of the field.
Most often the calculations are performed during some period of time. That's why fields include Time Stamps, representing the results of calculations in one definite moment.
