steel rope
Altair EmployeeHello,
I have a problem. In my current model I have two stell ropes. At the moment they are both defined as PROD elements. The disadvantage is, that PROD elements can take Pressure forces.
In reality steel ropes are not able to tape pressure forces. Both steel ropes have a preload set to 100 N.
Is there any possibility to solve that problem in optistruct?
Tanks for helping!

thanks for your reply
But how do i set the correct property to the CGap element?
I have created a card image: PGAP ..but I am not sure whats the meaning of the different options you can set. As you can see in the image bellow.
I just want a steel cable, with a preload of 1000 N. The steel cable material is steel and has a diameter of 3.141 mm. As in reality the steel cable should not take pressure forces.
I have also send you a small file, were i tried to play with the different options in the propertys.
Thanks for helping!
Hi @marvin1991
Unfortunately there is no tutorial or example available.
But you can apply preload using F0 field in PGAP. Please not that F0 will be ignored for a linear static subcase.
I suggest you to run quasi static analysis with F0 on PGAP.
Is it possilbe to create a preload on a CROD Element with the pretension manager?
I tried that on my model. It works fine but I´m not sure if the result is correct because normaly pretension manager is used for bolts.
Maybe you can tell me if that is a good alternative to CGAP elements?
