Good afternoon,

An equal pressure is being applied on both side spars in order to deform the middle part.I have tried the fixed the support and aplly remote displacement but the maximum tension appears to be on the green circle instead of the red area. I also tried to insert remote displacement on the COG node with all 6 DOF 0 and all this erros appear.

Can anybody help me here?

best

Hi Beatriz. The last 3 warnings are important. It appears you have multiple boundary conditions or contacts or joints applied the same entities. This will cause conflicts and the conditions will not be applied correctly. A suggestion would be to see if your model can solve with just fixed supports and gravity, then add conditions from there. n

Thanks for the answer,nWhen you say just fixed supports do you mean change those revolute joints?n

Any sort of analysis that can prove that the model holds together under it own weight. nStart with two parts. Fix one and apply gravity. Confirm that the model solves.nAdd the next part in and so on. n
