MATLAB: Change tetrahedral mesh to hexahedral

hexahedralmeshstltetrahedral

I'm using Matlab 2019b. I have an stl file, that I read using STL File Reader version 1.2.0.0:

[f,v] = stlread('filename');

I see quite straightforward how to get a tetrahedral mesh out of it, but I need a hexahedral one. How can I obtain it? Or is there an easy way to convert a tetrahedral mesh into hexahedral?

Thank you for your time.

Assuming you are trying to use PDE Toolbox, you can use the multicylinder function to create cylinder geometry and mesh as shown below.

R = 0.1;
H = 0.5;
gm = multicylinder(R,H);
% Assign it to a generic PDE model and plot the geometry.
model = createpde;
model.Geometry = gm;
figure
pdegplot(model,'FaceLabels','on')
%Generate mesh and plot the mesh.
generateMesh(model)
figure
pdemesh(model);
