如何加入vtk卷？

Question

我有5卷vtk。我通过制作5个不同的网格来获得这些体积。但现在我想把他们联合起来，我不知道怎么做。有人知道我怎么加入吗

mesh = build(malla(p2[0],p2[1],angulo1,angulo2)) #1-2
mesh2 = build(malla(p2[1],p2[2],angulo1,angulo2))#2-3
mesh3 = build(malla(p2[2],p2[3],angulo1,angulo2))#3-4
mesh4 = build(malla(p2[3],p2[4],angulo1,angulo2))#4-5
mesh5 = build(malla(p2[4],p2[5],angulo1,angulo2))#5-6
