HelloArray,It looks like you might have defined contact between the 2 smaller tubes and the press. The solver will calculate distance for between nodes of contact surfaces and assign them a near field or far field status. Only the nodes that are considered near open are considered for further computation. The pinball radius decides the boundary between near and far open field. In your case many nodes on the 2 pipes are considered as near open even if they are far enough and would never come in contact, this is because the pinball radius is set to program controlled. Define a pinball radius such that only the nodes that might come in contact are considered.
