problem with voltage display

[A.bitter]

Hello everyone, I am a mechanical engineering student, along with other colleagues we are studying the case of an industrial shed on which we are having some problems in displaying tensions in the 3 main directions, I explain better when we try to go to analyze the tensions in the "contour plot" for any direction we choose the screen that comes out is a set of red lines, moreover, going to list the nodal solutions gives us a series of warnings, such as:



[Chuckles] [Bleep] [Chuckles] [Bleep] [Chuckles] [Bleep] [Bleep] [Chuckles] [Bleep] [Chuckles] [Bleep] [Bleep] [Bleep] [Chuckles] [Bleep] [Bleep] [Bleep] [Bleep] [Bleep] [Chuckles] [Bleep] [Ch] [Bleep] [Chuckles] [Bleep] [Bleep]
beam/pipe elements are detected in the selected element set. they are
ignored in the nodal havingaging.

[Bleep] [Chuckles] [Bleep] [Chuckles] [Bleep] [Bleep] [Bleep] [Bleep] [Bleep] [Chuckles] [Bleep] [Bleep] [Bleep] [Chuckles] [Bleep] [Bleep] [Bleep] [Bleep] [Bleep] [Bleep] [Bleep] [Bleep]
no date is available for the selected model or data location
specifications.

I kindly ask you a help on how to solve this problem or at least understand what it might depend on.

if it is necessary I will post the log file.
