Hello,
I have extracted the results from modal analysis. The results look like the following picture.
As you seen in the table header, there are FX1, FY1, FZ1, MX1, MY1, MZ1 and FX2, FY2, FZ2, MX2, MY2, MZ2. So, I have two questions.
1. What does the number end of the FX, FY, FZ, MX, MY, MZ mean?
2. Displacement of each modeshape as shown in modal analysis result based on mass normalization. So, whether the force and moment of the result are the actual loading or not. Do they have unit, such as N, N*m or dimensionless?
Thank in advance
Greetings,
The following are defined as: FX1, FY1, FZ1, MX1, MY1, MZ1 and FX2, FY2, FZ2, MX2, MY2, MZ2
How did you generate this file?
Are you running a Time history?
Are you reviewing the MOD file?
What version of AutoPIPE are you using?

I generated this file by Export Eigen Values.
No, I'm just running Modal analysis to see modeshape as well as force and moment at each modeshape.
What is the MOD file?
The AutoPipe version v12.5
I would highly suggest that you upgrade to the most current version of the application, see wiki here for reasons why.
The MOD file is after checking the box on Time history, print modal results. See the folder location where the model is stored and search for a files whos extension is MOD. One can open this file with any text editor.
What's about the unit of force and moment?
I have notice something in eigen value export file. The deflection in eigen file does not appear the same as mode shape result (deflection result of mode shape).
For example, we focus on B39. There are deflection in floating results in AutoPIPE, but there are no results (0 in all directions) in eigen value file.
