Below is a demonstration of the features of the quadThick function

## Description

```clear; close all; clc;
```

## Examples

PLOT SETTINGS

```fontSize=20;
```

## Example: Using quadThick to create a hexahedral mesh

```% Creating an example polygon
ns=15;
t=linspace(0,pi,ns);
x=cos(t);
y=sin(t);
z=zeros(size(x));
Vc=flipud([x(:) y(:) z(:)]);

%Extruding polygon to a quadrilateral surface
cPar.depth=2;
cPar.dir=0;
cPar.closeLoopOpt=0;
cPar.numSteps=8;
[F,V]=polyExtrude(Vc,cPar);
```

Thickening quadrilaterial surface to hexahedral elements

```layerThickness=0.5;
numSteps=3;

%Use element2patch to get patch data
FE=element2patch(E);
```

Visualize mesh

```cFigure; hold on;
title('Hexahedral mesh');
gpatch(FE,VE,'bw','k',1);
axisGeom;
drawnow;
```

Create test data set

```[F,V]=quadSphere(3,1);
```

Thickening quadrilaterial surface to hexahedral elements

```layerThickness=0.4;
numSteps=3;

%Use element2patch to get patch data
FE=element2patch(E);
```

Visualize mesh

```cFigure; hold on;
title('Hexahedral mesh');
gpatch(FE,VE,'bw','k',1);
axisGeom;
drawnow;
```
```meshStruct.nodes=VE;
meshStruct.faces=FE;
meshStruct.elements=E;

meshView(meshStruct);
```
