Error # 1203 and no results button
Altair EmployeeHi everyone,
Currently I am using optistruct for the size optimization of a truss structure. Currently I am following the tutorial: Conceptual design of a bicycle frame.
This tutorial can be found in the following link:
I am able to follow al the steps but unfortunately I obtain the following error when I want to perform the analysis on the bicycle frame.
*** ERROR # 1203 *** in the input data:
Vector defined in fields 6-8 has zero length.
I understand that the problem arise from the fact the orientation of the beam is not properly defined. The problem is that I don't know how to fix it.
I have tried to define the orientation of the beams, which looks alright when I turn on the 1D detailed element representation. But still the error remains.
When I import the provided tutorial model files, then I am able to run the analysis but the results button does not appear. What could be the cause of these problems and where can I find the required information to solve these problems. Your feedback will be highly appreciated.
Regards, Mike

Altair EmployeeHi mike,
When the results button is not available, try to save your input file as a new file. Because the results button may dissapear if your overwrite your input file, Try to save as a new input file before you perform the optimization. I had the same problem and this worked for me, so hopefully it works for you too.
Regards,
Michael
Altair EmployeeYeah, Now it works! Thanks for all the feedback
Hi Mike,
Choose an orientation (according to your cross-section).
Go to 1D panel>> BAR >> Update >> change the orientation of the beam/bar elements
