Hi again,

> If I want to modify the source code, which file should I modify?

In [1] you can see that we assume the initial block is a cuboid.
You can go in [2] and declare 4 new vector<Real> attributes a,b,c,d containing the geometry of the initial block.
Then in [1], assign these values instead of using xmin,xmax,ymin,ymax,zmin,zmax.
Also, please be careful that the planes you will define are consistent with the origin of the coordinate system, which at the moment is set as firstBlockCentre=[0,0,0].

Last, the tricky part of these changes is that you still have to define
boundarySizeXmin/Xmax/Ymin/Ymax/Zmin/Zmax, denoting outer boundaries of
the initial block.

> And if I want to fix some of the joints, what should I do?

What do you mean when you say "fix" some of the joints?

Keep me posted if you need any help,
Vasileios
