Analysis of a simple power line (cables and poles)

Hi all, I have had a go at learning calculix. I can see it is a great tool but not being an engineer it is over my head. I have a simple test case and I wonder if anyone would mind looking at the issue and perhaps modelling it. You can read a description at Please ask any questions. Thanks.

CalculiX has 1D elements (beam and truss) that you could use for such analysis. Internally they are expanded to solids but it shouldn’t be a problem. Just be sure to run the analysis a few times with different numbers and types of elements to verify the correctness of the results - beam elements in CalculiX are particularly sensitive to that.
