I want to simulate the model with these following steps :

1-In the first step, the beams were simply supported at both ends. The column and the blind bolts were fixed temporarily in case of the motion of free bodies. Meanwhile, a low level of pretension was applied to all bolts to ensure that the contact interaction had been established.

2-In the second step, the temporary constraints for the column and blind bolts were removed, and the bolt pretension was increased to the value that was mentioned above. Simultaneously, the vertical loading was applied on top of the column through displacement control up to 110 mm.

so I do the following:

1-I ensure that all the contacts are closed

2-I set Number of Steps to 2 and make Large Deflection is On.

But I get the following error:

1-Not enough constraints appear to be applied to prevent rigid body motion.  This may lead to solution warnings or errors.  Check results carefully.

2-One or more objects is using a deformable behavior but is applied to a collinear set of nodes.  This is not recommended and can cause solver difficulties.  Check the Solver Output on the Solution Information object to identify the offending load.

3-An internal solution magnitude limit was exceeded. Please check your Environment for inappropriate load values or insufficient supports.  Please see the Troubleshooting section of the Help System for more information.

4-An error occurred inside the SOLVER module: general error.
