1.1 Conventions
- A triangulation, T, is a set of triangles covering a domain
refered later as Omega
- Each vertex has a number iv, a region reference number
region, and a boundary reference number ib which is zero for
internal points.
- An array-function is an array of values on the vertices of T. It
represents a piecewise linear continuous (or discontinuous if
precise
is used) function on Omega.
- In an integrated environment Gfem has the notion of Project: files
shown on the desktop as documents with an icon like a triangulated
rectangle (on the Macintosh).
- A project contains a program, the last triangulation created and one
array function, namely the last function displayed.
