hi guys, I am new to the forum so first I greet you and thank you in advance for patience.
I will try to expose my problem:
I am performing a modeling work of a masonry building, I did a modal analysis and a spectral analysis and I had no problem because I didn't need any stress, but now that I need I have problems with static analysis.
I would now simply want to get the stresses on my structure from the gravitational load alone, or by applying any type of load.
So I do a static analysis, and when I solve it the only solution I get, it is in terms of movements and deformations, but I can't in any way get the stress and forces (fy,fx,mx...)
the elements I used for modeling are shell281 (ansys v14).
It makes me too strange, I do not receive warnings, or errors, but when I finally try to plot the stresses, or create etables with the prompts I ask, I see the following warnings:
-the request is not avaiable. the plnsol command is ignored (when I go to view stress at knots)
-element force is known avaiable, (when instead I try to make an etable with forces. )
I repeat the deformations I give, all appropriate, so I do not think it is a problem of previous phases because the solution finds it, are the forces that I cannot obtain,
I tried to train you the project, (it is in ansys 14)
Try also only to do static analysis with only gravitational loads. (load, gravity...ecc) will give the same problem as if applied any force).
Thank you and I hope you can help me...
