QUAD_MESH_ORDER1
Quadrilateral Mesh with Piecewise Constant Data


QUAD_MESH_ORDER1 is a data directory which contains examples of files that define a quad mesh and an associated data value that is constant over each element of the mesh.

An order 1 quad mesh is a mesh of a 2D region based on quadrilaterals, with a piecewise constant value. An order1 quad mesh can be defined by three files:

POOL is a simple rectilinear mesh using 28 points in a 7x4 grid, forming 18 elements, along with a value that we can think of as the depth of a swimming pool measured once in each element.
