Extract nodal forces from a truss
Altair EmployeeHi,
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.

Hi Prakash,
tnx for the answer. I've produced the .gpf file and there are the Grid point forces for node # listed. The values of one node can be seen below. There are The XYZ-forces and -moments. But what are the values 'Appl., F-MPC, BAR and Total'? Why is the total value that small?
Can you give me some explanation regarding the below listed values?
Best regards
Wiko
