Discussion load on guide support

Question

Hello, 
 I have modeled riser and input guide clamps by guides with gap 5 mm preventing movement lateral movement, whereas the pipe can move freely in the vertical direction. However, I extract the force load at support in gravity case, I saw that there are force in vertical direction and I can't imagine where they are from.

Greetings, 
 Please ignore all individual load cases and only concern yourself with the operating conditions results on the guides. 
 Does the support have any load on the supports for the operating condition? 
 If yes, then perform a load sequence study on the node point's displacement for each load case per the combination / analysis summary settings.

Greetings, 
 I apologize for not providing a clear response in my last communication. 
 Please ignore all individual load cases (example, Gravity, Pressure, Temperature) and only look at the Operating conditions (example GRT1P1, etc..). If there are concerns about what is contributing to the operating condition, then look at the individual load cases for better understanding of which loads and magnitudes are contributing to results. It would have been better if you had provided a support report for the indicated node point. The report should contain the operating condition and all individual load cases that make up the combination. This way I / others would have a clear picture of the issue. Also indicate what are the gap settings on this support. 
 Also, suggest to not use the floating results dialog, instead use the Results grids, checking load cases on and off as needed. 
 In this case, I see that the riser is not plumb, therefore there maybe a load on the support due to the gravity load if the support gap closes. I would definitely look at the animation of the various load cases to see how the model is moving.
