Static Structural Analysis


#1

Hi,
I am a new user of SimScale and I was trying our some simple problems I wanted to figure out how large assemblies are analysed on SimScale more specifically how to define the connections/joints between the parts of the assembly.

So I modeled a simple assembly shown below
tempsnip

I gave cyclic symmetry for the revolute joints and fixed the other two supports.
After running, solver error message comes up always.

Am i doing anything wrong ? Is there any other way to define revolute joints ?

Thanks and Regards,
Vignesh

Hi @VigneshKC,

Can you share a link to your project so we can take a look at it?

Thanks,

Sorry for the late response @VigneshKC!

@ggiraldo, could you give it a quick spin if you have the time? Would be awesome!

Cheers,

Hi @VigneshKC,

Sorry for the late response.

Imade a copy of your project here.

The Cyclic Symmetry boundary condition is used if you are modeling a sector of a revolved model such as a fan disk or a pressure vessel. What you want to use in this case is the Sliding Boundary condition. This works well for linear problems with small motion. I also had to constrain the top bar in teh Z-direction.

Please take a look and let me know if you have any questions.

Hi @cjquijano
Thanks a lot for your response. I will certainly explore more to get a better understanding.
