The anchor points were supposed to be as high as the connections on the structure, but it kept resulting in crashes. Thus I had to lower the anchor points 0,01 m below the connection points. The problem is the cables became parabolic upwards as seen in the image below. I tried putting the anchor points below the water line and it still was parabolic upwards. The cables are non-linear catenary with cable dynamics turned on.
