Cells are determined by their connectivity. They can have 0,1,2 or 3 dimension.<br> <br><a name=""></a> <nobr><b>Component</b></nobr><br> One integer or real value can correspond to each component of a field and to each entity of a mesh<br> <br><a name="bm_D"></a> <nobr><b>Descendant connectivity</b></nobr><br> It is a description of the entities of the mesh with dimension N. This description is made by an ordered list of geometrical entities (nodes, edges, or faces) with dimension N-1.<br> <br><a name="bm_E"></a> <nobr><b>Edge</b></nobr><br> An edge of a volumetric or surface mesh. It is composed of 2 or 3 nodes (2 vertex nodes and optionally one middle node).<br> <br><a name=""></a> <nobr><b>Entity of a mesh</b></nobr><br> Geometrical component of the mesh: node, cell, face and edge. Faces and edges are only intermediate entities allowing to define the cells in descendant connectivity.<br> <br><a name=""></a> <nobr><b>Equivalence</b></nobr><br> Equivalence represents a list of correspondance 2 by 2 of the entities of the same dimension.<br> <br><a name="bm_F"></a> <nobr><b>Face</b></nobr><br> Face of a volumetrical cell (triangle, quadrangle).<br> <br><a name=""></a> <nobr><b>Family</b></nobr><br> Entities of a mesh are described by a certain number of characteristics (boundary conditions, groups membership). Families represent classes equivalent to these characteristics (two entities of a mesh can belong to the same family if they have the same characteristics). Every family is determined by a set of attributes and a list of groups membership.<br> <br><a name=""></a> <nobr><b>Field</b></nobr><br> Field consists of one or several scalar components. One definite type is associated to the given field and the values corresponding to different components are all of the same type.<br> <br><a name=""></a> <nobr><b>Field profile</b></nobr><br> Fields can be defined only on one part of the mesh. Profile of the field or profile of the component of a field indicates which entities of the mesh contain values.<br> <br><a name="bm_G"></a> <nobr><b>Group</b></nobr><br> Unordered set of entities of a mesh. One entity can belong to several groups.<br> <br><a name="bm_M"></a> <nobr><b>Mesh</b></nobr><br> Mesh is described by its geometry: list of nodes and list of cells which constitute this mesh. Supplementary information is added with the help of families (initial, boundary conditions).<br> <br><a name="bm_N"></a> <nobr><b>Nodal connectivity</b></nobr><br> It is a description of an entity of the mesh by an ordered list of nodes constituting this entity.<br> <br><a name=""></a> <nobr><b>Node</b></nobr><br> Node can be an isolated node of a mesh, a vertex or middle node of an edge. A node is associated to a point.<br> <br><a name="bm_P"></a> <nobr><b>Point</b></nobr><br> Geometrical entity determined by its coordinates in the space.<br> <br><a name="bm_R"></a> <nobr><b>Reference connectivity</b></nobr><br> For each type of entity of a mesh, reference connectivity define the topology of an entity.<br> <br><a name=""></a> <nobr><b>Result</b></nobr><br> List of fields referring to one mesh.<br> <br><a name="bm_S"></a> <nobr><b>Study</b></nobr><br> Study represents a chain of sequences of calculations.<br> <br><br></p> </body> </html>
