Load-displacement curve

[mari.95]

Hello to everyone, I have a question. I made a static analysis of a beam and I want to extrapolate the load-displacement curve. I set the monitor after the analysis steps but I can't see the window of the monitor when I run the analysis. Then, I tried to make the curve in postprocessing evaluating displacement in z in the node of the maximum deflection and reaction force in z at the support (summing the reaction of every node of the bearing's surface), but how can I see the results using the function monitor?
Here there's my sdc. file. Thanks in advance for your support.

Dear Mari.95
move up the monitor before the analysis. Remember that the analysis that you like to monitor must be after the monitor.
If it still does not work, you can launch the monitor manually. Click on the bat file indicated in the picture attached.
The model is very nice and runs smoothly. You can improve it with a structured mesh. To have a structured mesh you need to be sure to have the volume enclosed by 6 faces or the surfaces enclosed by 4 edges.
Otherwise, you can use the embedded conditions to connect incompatible meshes. The denser mesh should be the slave. Additional note, pay attention that the stresses at the contact will be not precise. The next advanced webinar will be on this topic.
If you cut the volumes you can easily do it. Then use brick bbarbrick.
You will reduce drastically the number of elements and improve the performance.

Thanks for the suggestions, I'll try to move up the monitor. About the improvement of the model, I don't know the reason why I can't create a structured mesh. In detail, I tried to cut the volume so I used the merge command at the end but when I choose the structured mesh I can't see any difference, and using a bbarbrick I had incompatibility because I had 8 nodes for the element definition but the mesh still had 4 nodes. Have I made mistakes creating the mesh? Thanks for your help.

Please post the new model so we can check it

This is the file with changes. Thanks in advance.

I made other changes. I can realize the structured mesh but I have other problems when I try to run the analysis.

Dear Mari,
my lovely Horace told me to check your model.
You did not divide the volume correctly. When you merge the surfaces, pay attention to merge them only with the volumes.
I run the attached model. It does not converge, you might have to check it again. The curve seems fine.

Thank you very much for your help! I understand the problem.
Have a good evening!

We noticed that the symmetry condition is applied only at the rebars, please apply it to the entire face.
Another thing, the support is fixed, I think it should rotate, please check

Yes thanks, I just corrected these errors.
