Meshing

During the meshing it freezes even after taking a tolerance of 10mm.

Hi Sir @Stephane.kapetanovic

Thanks for your advice and help.

Just considered one level of the structure but i keep having thesame warning (Incoherent meshes), even with no overlap panel .

hi @Djokaboris

you should take a look at this report (0 to 10).

Best Regards

Note :

Note that, although the GetMainNodes program is not designed for this purpose, you can check which nodes are on the periphery of meshed panels. By making a selection and limiting the view to nodes, you can see directly where problems are concentrated. Problems usually occur where nodes appear superimposed, or where a large concentration of mesh is focused on one area.

Many thanks from your reply Sir @Stephane.kapetanovic . I just took the time(almost a day) to work on the file and i'm 100% sure that there are no unconnected nodes.

I see the meshes are concentrated on 3 panels leading to incoherent meshes warnings. Is this due to the difference in size of panels ??

What disturbs the most is that the load distribution regions and forces generated automatically doesn't display Nothing. The beam and slabs are on thesame level as you recommended. Is it due the warning?

Your beams are sometimes far away from your panels. They no longer intervene in the distribution of the load. The nodes are not isolated, but the finite elements overlap because the nodes, bars, and panel points are not precisely positioned. In the report you will find the areas where you need to correct the geometry. You won't get proper results without it.

i can't detect any beam far apart. The report send is the past report that had soo many errors. In this new file just send, i can't detect any errors but only load distribution problems

When utilizing the delaunay meshing there is no meshing concentration but Robot still detect Incoherent meshes. i don't know if its because there are trapezoidal panels.

You are free to find the solution that suits you best. It does not seem wise to circumvent imperfections by refining the mesh.

Increase the number of decimal places in the preferences and zoom in on the singular points.

HI @Djokaboris

here after the new report. you're on your way to finishing the structure corrections

After examining your file, it seems that the lines of the two floors are not orthogonal and that the plumbing cannot be done correctly. if you can import a dwg file, you can export it too

Many thanks for your time Sir. right now there's no errors nor warnings, but the last problem is that the slabs doesn't distribute any load while it's on thesame level as the beam.

MY APOLOGIES FOR LOADING THE FORUM . FIND THE SOLUTION OF LOAD DISTRIBUTION PROBLEM. I WILL LIKE TO THANK YOU @Stephane.kapetanovic FOR YOUR TIME TO LOOK AT THE FILE, THAT HELPED UNDERSTAND HOW RSA FUNCTIONS IN TERMS OF INSTABILITIES AND MESHINGS

MANY TIMES FOR YOUR TIME AND BEST REGARDS
