Introduction

This part of the user guide describes the contents of the DS and the tools associated with them. (creation and manipulation).

The following types of DS are described:

AMAT :

assembled matrix - compact storage,

ATRI :

full upper-triangular matrix,

B :

assembled right-hand-side (RHS) or vectors (solutions, residuals, ...),

BDCL :

description of the constraints imposed by the boundary conditions,

COOR :

coordinates of the mesh points (nodes),

FORC :

description of the data required for the computation of the RHS,

GEOM :

geometric type description of a 3D mesh,

MAIL :

topology and interpolation of the mesh elements,

MILI :

description of the data required for the computation of the matrices,

MPLR :

description of the referenced boundaries,

MUA :

assembled matrix - skyline storage,

NDL1 :

pointer to the degrees of freedom per node,

NOPO :

mesh,

TAE :

element arrays corresponding to each element,

TYNO :

description of each node type,

VVPR :

eigenvalues and eigenvectors.

Remark: The concepts required for a good understanding of the notion of a DS have already been presented in this user guide and are assumed to be known.
