Points
Definition
Defining the geometry is a significant step. Indeed, in Metafor, most commands are applied on geometric entities, and not on the mesh itself. Therefore, the data sets are easy to parametrize, since the number of mesh is not taken into account in the writing of boundary conditions.
Points
are the most basic entities. It is from the Points
that most Curves
are defined.
pt = pointset.define(number, x, y [, z])
number | user number of the point (must be unique and $\geq 1$) |
x , y , z | coordinates of this point ($z=0$ by default) |
Example
The four summits of a square of length $L$:
L=5 pointset = geometry.getPointset() pt1 = pointset.define(1, 0, 0) pt2 = pointset.define(2, L, 0) pt3 = pointset.define(3, L, L) pt4 = pointset.define(4, 0, L)
