Below is a demonstration of the features of the hexMeshBox function
clear; close all; clc;
This function generates a mesh structure containing element and node data for a hexahedral element meshed box. The box dimensions in each of the 3 directions are based on the boxDim input (1x3 vector). The number of elements in each direction is based on the boxEl input (1x3) vector. Finally the type of output structure is based on the optional final input outputStructType. By choosing 1 the old mesh structure is used. By using the option 2 the newer output structure form is used which is compatible with the meshView function. The default option is 1.
CREATING A MESHED BOX
boxDim=[5 6 7]; boxEl=[4 5 6]; [meshStruct]=hexMeshBox(boxDim,boxEl); E=meshStruct.E; V=meshStruct.V; F=meshStruct.F; Fb=meshStruct.Fb; faceBoundaryMarker=meshStruct.faceBoundaryMarker;
cFigure; title('Box boundaries faces','FontSize',fontSize); hold on; gpatch(Fb,V,faceBoundaryMarker,'k',faceAlpha1); % patchNormPlot(Fb,V); axisGeom(gca,fontSize); colormap(gjet(6)); icolorbar; drawnow;
Visualizing model internal mesh with meshView
%Recreate mesh but output structure compatible with meshView [meshStruct]=hexMeshBox(boxDim,boxEl,2); %Use meshView to visualize mesh meshView(meshStruct);
