Using NvCloth, But Mesh(Vertex) is broken

Question

I used nvcloth 1.1.6

I initialize via cuda, and created a factory.

I made the character's clothes mesh into Cloth* using NvClothCookFabricFromMesh.

And after applying the setting values of the nvcloth example, I run the cloth simulation, but the mesh is broken as shown in the figure below.

Do any of you know the reason??

Apply wind to clothes, the triangular pieces move back and forth in the direction of the wind.
