Extract nodal forces from a truss

Altair Forum User

Hi,

 

I'm currently analyzing a truss (3D) which is modeled with CBEAML-elements. The model is made out of lines and the lines where meshed via 'line mesh'.

What I do need are the forces acting on the 'knots' where the Beams are connected together. I've activated in the output card already 'GPFORCE'&''GPSTRESS' but the results in HyperView are not satisfactory...

 

In the post processing are the results 'Grid Point Forces (s)' & 'Grid Point Forces (Elements)' available.  

'Grip Point Forces (s)' - results (Total FX for example) show very low forces (3.3*E-10) and  'Grid Point Forces (Elements)' doesn't provide any results....

 

Can some one please give some hints for solving such a problem? I need only the nodal forces (as shown in the figure below; point E for example) of the connections so I can design mounting brackets for the truss assembly

 

 

Best regards

Hi Wiko,

 

Can you extract GP Forces in OPTI format instead?

 

This will write a .gpf file in working directory and open the same in any text editor. 

 

Check the forces in the file and let us know if you see anything unusual.
