Hi

 

I'm working on a steel truss power mast and during the calculation of the structural model Robot gives me also the ERROR Nr. 5000. What am I doing wrong?

 

Many thanks in advance!

Is the nonlinear analysis convergent? Is it the same after you change the solver type?

Nonlinear analysis works fine if not selecting Buckling in the "Change of Analysis Type for Selection of Cases" dialog box. Originally I was using Sparse M solver with MDA when I got the Error Nr. 5000. When changing the solver type to Automatic, Error Nr. 5000 appears again (Seems like Sparse M is used In Automatic as well). By choosing Sparse (without M), after a 20 minute run, I get the results. I also tried Skyline wich runs approximately 5 hours. I got the warning: "Instability (of type 3) detected at node 217 in direction RX". Seems like it is releated to big differences in stiffness of elements. Am I right?

 

If so, is it correct to choose Sparse as solver and go on with the design?

 

I'm sending the file separately so You could have a look.

 

Many thanks in advance!

We haven't received the file If you checked the cause of the instability and considered it as not having any negative effect on the obtained results then I think it is.

I have made the quick initial check running your model with for case 1 only. There is no instability reported.

The values of load are corrupted.
