Hello,everyone.

 

     I am a new user of the hyperworks. And I want to analysis a .iges file with many lines as you can see in the attachment. I want assign the lines with beam property.

 

     The problem I get is that when I use 'line mesh' with pbeaml(beam section is a circle) , bar2, and auto settings, some lines can't be assign the property correctly, as you can see in the .png file(the picture). I guess the direction of the beamsection is not correctly set, because when I analysis it by optistruct, I get an error that the 6~8 field of cbeam is zero length. But I want if there any method can generate what I want correctly.

 

    I want analysis a more complex lattice model(with lines in all direction), and before this I use this simple model as a practise.

 

    Thank you for you time, and any advise will be appreciate.

    Hi @donggua

    That is because the vector definition has zero magnitude. This causes an orientation issue.

     

    Can you change the orientation of the red lined vertical elements?

     

    Go to BEAM property>> Orientation>> change to say Z axis and check,
