\addtogroup chi_mesh__BooleanLogicalVolume
## Additional Example A
The code below defines a logical volume that is within logical volume 1 but
outside logical volume 2
\code
chi_mesh.BooleanLogicalVolume.Create
({
  params = {{true, lv1}, {false, lv2}}
})
\endcode
 
## Additional Example B
\code
chiMeshHandlerCreate()
 
mesh={}
N=40
L=5
xmin = -L/2
dx = L/N
for i=1,(N+1) do
  k=i-1
  mesh[i] = xmin + k*dx
end
chiMeshCreateUnpartitioned3DOrthoMesh(mesh,mesh,mesh)
chiVolumeMesherExecute();
 
lv1 = chi_mesh.SphereLogicalVolume.Create({r = 1.3, x=1.0, y=-1.0, z=2.0})
 
lv2 = chi_mesh.RCCLogicalVolume.Create({r = 1.3,
                                        x0=-0.8, y0=-0.8, z0=-1.5,
                                        vx=1.0, vy=1.0, vz=3.0})
lv3 = chi_mesh.BooleanLogicalVolume.Create
({
  parts = { { op=true, lv=lv2 },
            { op=false, lv=lv1 } }
})
chiVolumeMesherSetProperty(MATID_FROMLOGICAL, lv3, 1)
 
chiMeshHandlerExportMeshToVTK("lv_boolean_test1")
