Bolt problem on a simulation

Hello, for the first time I'm trying to put bolts on a frame screwed into a tube by two bolts.

Do you have to put a connection between the sets or not? In my case I tried both options.

When I create my bolts I enter the two edges and the diameter

 

During the simulation I have a flaw

 

Warning: Pre-load in at least one bolt connector is zero 
 Do you wish to continue?

 

I don't understand what to do.

On the other hand, should I enter prestressed or not?

 

Thank you for your help

 

Is it possible to have a screenshot of the board with the holes of the connector that is causing problems?

Hello 

To put imposed bolt-type movements, you first need to create a virtual wall. When creating the imposed displacement, you will only have to select the contact edge of the bolt and the virtual wall.

Personally, I only put one bolt at a time.

Hoping to have answered your question.

Here is the screenshot

On the other hand I create a virtual wall or?

I was able to move forward I think

I made a contact between sets of the no penetration type.

I can do the simulation

The results are attached.

What do you think? Is it good
