Any one help to solve this problem? Thanks a lot.

You can simply raycast against the rope mesh, why wouldn't that work?. You can get a reference to it from its MeshFilter component.

Physcis.Raycast  needs a collider.  I added a mesh collider to the Rope Mesh, but the collider is  fixed when the rope is animating. My solution so far is updating the mesh collider in Update() function. Like this:

Code:

void Update () {
GetComponent<MeshCollider>().sharedMesh = null;
GetComponent<MeshCollider> ().sharedMesh = GetComponent<MeshFilter> ().sharedMesh;
}

Are there any better solutions?  Thanks again.
