clear; close all; clc;

Syntax

[meshStruct]=hexMeshSphere(optionStruct);

Description

This function creates a hexahedral mesh for a sphere based on the input struction optionStruct.

Examples

Plot settings

fontSize=15;
faceAlpha1=1;
edgeColor=0.25*ones(1,3);
edgeWidth=2;

Creating a solid hexahedral mesh sphere

%Control settings
optionStruct.sphereRadius=10;
optionStruct.coreRadius=5;
optionStruct.numElementsMantel=5;
optionStruct.numElementsCore=8;
optionStruct.makeHollow=0;
optionStruct.outputStructType=2;

%Creating sphere
[meshStruct]=hexMeshSphere(optionStruct);

% Access model element and patch data
Fb=meshStruct.facesBoundary;
Cb=meshStruct.boundaryMarker;
V=meshStruct.nodes;
E=meshStruct.elements;

Visualize mesh

hFig=cFigure;
subplot(1,2,1); hold on;
title('Boundary surfaces','FontSize',fontSize);
gpatch(Fb,V,Cb,'k',0.5);
% patchNormPlot(Fb,V);
axisGeom(gca,fontSize);
colormap(gjet); icolorbar;
camlight headlight;

hs=subplot(1,2,2); hold on;
title('Cut view of solid mesh','FontSize',fontSize);
optionStruct.hFig=[hFig hs];
gpatch(Fb,V,'kw','none',0.25);
meshView(meshStruct,optionStruct);
axisGeom(gca,fontSize);
drawnow;
