Linear rectangular structured hexahedral mesh

Mesh.Hex1

Hex1 P1 Hexahedral structured mesh rectangle (MATLAB)

H = Hex1(x0,x1,nxe,y0,y1,nye,z0,z1,nze)

Methods

Hex1 includes the following methods:

• Hex1() - The constructor, creates the Hex1Mesh object.
• Neighbors() - Returns a m-by-4 matrix containing element indices to the neighbors.
• vizMesh()
• RefineLocal()
• RefineLocal()
• boundaryInds()
• baseHexP1()

Installation

Put the contents of this repo in the +Mesh@Hex1 folder somewhere in your MATLAB path.

Demo

%Create mesh
ne = 2;
x0 = -1;x1 = 1;y0 = -1;y1 = 1;z0 = -1;z1 = 1;
nxe = ne;nye = ne;nze = ne;
H = Hex1Mesh(x0,x1,nxe,y0,y1,nye,z0,z1,nze);
H.vizMesh('ElementNumbers','NodeNumbers');

Mesh numbering

The mesh is numbered according to the figure below. The red and cyan colors are used to explain the refinement algorithm.
