21
22 /* A mesh is built from nodes and elements which are describing the
23 domain, the surface and point sources. (the latter are needed to
24 establish links with other codes, in particular to particle
25 codes). The nodes are stored a Finley_NodeFile and elements in a
26 Finley_ElementFile. A Finley_NodeFile and three Finley_ElementFile
27 containing the elements describing the domain, surface and point
28 sources respectively. Notice that the surface elements do not
29 necessaryly cover the entire surface of the domain. */
30
31 /* The element type is fixed by the reference element, see
32 ReferenceElement.h. The numbering of the nodes starts with 0. */
33
34 /* Important: it is assumed that every node is appearing in at least
35 one element or surface element and that any node used in an
36 element, surface element or as a point is specified in the
37 Finley_Node, see also Finley_resolveNodeIds. */
38
39 /* In some cases it is useful to refer to a mesh entirly built from
40 order 1 (=linear) elements. The linear version of the mesh can be
41 accessed by referning to the first few nodes of each element
42 (thanks to the way the nodes are ordered). As the numbering of
43 these nodes is not continuous a relabeling vectors are introduced
44 in the Finley_NodeFile. This feature is not fully implemented
45 yet. */
46
47 /* allnodes and elements are tagged. the tag allows to group nodes and
48 elements. A typical application is to mark surface elements on a
49 certain portion of the domain with the same tag. All these surface
50 elements can then assigned the same value eg. for the pressure. */
51
52 /* Thespacial dimension is determined by the type of elements
53 used. The spacial dimension should be accessed by the function
54 Finley_Mesh_getDim. Notice that the element type also determines
55 the type of surface elements to be used. */
