Hello . I tried to not meshing WaLL and the Model showed Period , Ux, Uy , Rz .
Was the result reliable ? We usually mesh Wall and Run and analyse mode shape
my tutor teacher ran that file in his computer and its fine . I ran it again and the problem still there . If my computer has problem so why another model shows fine result .
I did post 2 files above.
the first file is the original version
the second file is after I cut of stories to run Standard solver .
I really need help :((
yes , I did cut off the story has red walls. there are only 3 stories which have columns , beams, and Wall core.
I checked and these joints appeared on the Wall Core , at the position I meshed . That are faded joints , how can I choose and fix it ?
I deleted Wall Core and drawed it again ...
I choose Shell-thick for slab and wall.
My model has column system run from the second Base to the Story 3 . And I have the Transfer beam at this Story ( to transmit loads from walls to columns). From the story 3 to the Roof is Wall system . besides, I also reduced the hardness of Wall every 10...
oh I see it , most of these joints are located on the wall . These joints 're at the position which I meshed .
I used Auto mesh option to mesh( Mesh size is 1m for floor and wall , I also add restraint on edge for wall ) .
I made another model before and It's find . But this model has this...
I used the Standard solver and the message :

hello , I did cut off 31 stories above . after running , the negative eigenvalues reduced , only 230 instead of 4981 .
This is the first story above the transfer beam . What happening with that walls ?? . Is it the reaseon ? The picture and the file afte I cut off the stories below . Can you...
oh thank you , but maybe it'snot the cause , my meshing 's good .
My model has a Transfer beam (0.8x1.8). are there any problem about restraint between Column , Transfer beamm, and Wall system above ??
I did it but it took a lot of time . I used standard solver , and waited for 45min but it 's still not run.
I made the model again carefully but I still received this message again .
Do you know the main cause ? or your friend know?
Hello everyone , I need help. After running the Model , I checked the log and it showed that :
* * * W A R N I N G * * *
THE STRUCTURE IS UNSTABLE OR ILL-CONDITIONED !!
CHECK THE STRUCTURE CAREFULLY FOR:
- INADEQUATE SUPPORT CONDITIONS, OR
- ONE OR MORE INTERNAL MECHANISMS, OR
- ZERO OR...
