abaqus beginners

[andrew16]

Hello everyone, I am new to the forum, as I am for abaqus. I use the version abaqus/cae 6.13.
I have to use this program for the thesis, of which the details maybe I will tell you in the future. for now I am doing some tutorials that I find on the internet. to begin I have made a quite recognizable example, that of a shelf (I think it is the example suggested by manual abaqus). Well, I replicated it and it all comes back. to have a match and start understanding the results and their control I tried to do the same exercise by hand and save small percentage errors the same result in terms of tensions to the disaster. I then tried to change mesh (change the size in seed!!) from 10 to 5 for example (I actually made many of them) and what I noticed that the results always change and not just disconnecting from the manual calculation of much. If anyone can let me down on the reason, and on the error I'd be grateful. Thank you.

Sure that changing the mesh results change so much?
I do not know abaqus but if the model is correct, even changing the mesh, the result changes, but little.

try to bring back the found values of arrow at the end with different mesh values.

I had not checked the arrow before, this changes little but still changes, and however I agree with you that the result changes, but should not get away from the solution "exact" (made by hand and then on sap2000). I attach the voltage photos (s11) and move. are with mesh (seeds) 5 and 10

You used a beam element to shape the right beam?
That sounds weird.

Yes, I've posted you a flat view but it's a 3d model. I also did a test by inflating even more is the voltage increases by 100n/mm2. There's something I'm getting out of here so
