Re: Beam Element Properties

Ah ok, And how do I get values for a Hollow box section?

There's a formula here but it doesn't give the same answers as Aurora.

Beam Element Properties

Hi, For the beam elements I can use Aurora's GUI for calculating the cross-section properties. However I am a little confused. What is Wt? - the second modulus for torsion. all my calculations on beams before have used J - the second moment of area for torsion and G - the shear modulus (material not...

Re: simple text output

Thanks for your help. like you said via email, it was the orientation control point that was wrong. I'm not sure why though: In my case, I had a beam 25 element from (0,0,0) to (100,0,0)[on the x axis] The point 3 (control point) 1 - Does not work at (0,1,0) [not on the x axis] 2 - Does work at (0,0...

Re: simple text output

Ah ok, I made a silly mistake, thanks. I've re-run the simulation but now I don't get any nodal forces, only displacements. Do you have any more suggestions?

Beam Element

Hi,

In Aurora I can use beam element 25 - is this element also available in v14? I can't find it in the user's guide.

Thanks
