Execution Problem 3060

[Anonymous]

Hello,

I need to perform a global buckling analysis to check if the building is sway or non-sway and I’m getting the annoying error “3060 execution problema”.

When running, the program reports type 3 instability in one node. I checked the node and corresponds to an intermediate node of a wall mesh. I regenerate the mesh for that Wall and then I still get an instability of type 3 in one node, but now it is located in a slab in another side of the building.

I steel need to perform the global buckling analysis but I don’t know what else I can do…

thanks in advance

In this particular case:

- correct model to get rid of overlapping bars and incoherent meshes

- set model generation tolerance 1mm

Hi 

I tried to apply  the method in the video to my meshing problem, but i can't fixe them.

I don't know which node to choose to move it in another place.

Any help for this model?

Sorry

here are the nodes

Just move some nodes to get coherent mesh

File attached.

Thanks so much Rafal

Hi @Rafal.Gaweda 

I have a structure with this error. I tried to solve it but failed. Hope you help me. Thanks very much!

Hi @ledinhchinh0409 

Because of lack of drilling rotation degree of freedom to prevent panels supported in one node You have to add rigid links

hi. @Rafal.Gaweda 

 Thanks you very much!

Great.

Thanks for your help. I used Roman's excellent Spider Pro 1.8 tool. And successfully processed the error. . Now there's only a warning about instability 3. Can I ignore it?
