Hello,

I've got such problem and didn't suceed to solve it, (or find right answer). Problem as you can see in printscreen attached) in walls some displacaments from selfweights are really strange. I veridied file (not once) everything looks fine, I tried to regenerate mesh for these panels, and so on. nothing helped.

I couldn't attache file cause it's too big

Don't forget this is displacememt normal to the panel, so it's not vertical deformation you are looking at here.

Could be from bending out of plane for that panel?

[#3]

I understand that but what looks strange to me is difference between two close panels, in one displacament in one dirrections in other opposite, but local axes are in same dirrections

[#4]

Could you attach this model please?

[#5]

well it's quite big 445Mb, so only such way

Try that:

- turn off kinematic links

- mesh panels,

- freeze meshes

- check FE local coordinate systems comparing to these two panels systems - Z direction.

If they are opposite - remesh panel with wrong direction on FEs, if it does not help, open file in repair mode and then remesh this \ these panels.

My results are OK doing nothing with model

kinematic links are turned off,

panels are meshed and freezed, (I've tried to remesh them several times).

But FE local coordinate system differs (somehow I could not imagine that it can differ from panels local coordinate system).

But I can't understand anything now i remesh panel, and while looking at FE local system on everything looks fine, but if I just turn local coord system of panels on FE local system (view) changes. Problem about repari mode is that repair mode explodes most of openings (turns them into geometrical objects).

Ok, I've tried repair mode and meshing afterwards, nothing helps. For some panels local panel and FE local coord sys z dirrection differs. I'm out of ideas, I'm using RSAP 2013 SP2 (64bt).

I know that this file was created in older version. I can't understand these coord systems differ.

[#9]

One idea, can't this be of some stange instalation feature (particular in my pc) or some rubish files left somewhere in pc.

TRy this: after meshing and freezing meshes copy this panle aside from model ie with vector -10 0 0 and observe LCS of panel and FEs - they should be OK now, then remove copy of this panel.
