Is this a bug? Wrong deflections!!!

See the attached.

Wrong deflections are reported.

See Bar #8 as an example.

The problem is that cantiliver deflection comparison is wrong!

 

Why is uz used rather than UZ?

 

I have attached output from another model.  Look at Bar No 8 deflections please.

I think this is correct for the parameters you defined. You need to 'tell' the program that you this is a cantilver Smiley Happy

I would expect the software to discern a cantilever based on support conditions.  Smiley Frustrated

I'd rather decide myself if this is a cantilever or a suspended beam. Anyway currently you have to decide yourself Smiley Happy

Suggest that the "cantilever option" be a Bar Property rather than burying the option outside of analysis / results and down several levels.Smiley Frustrated
