Rod Stability
Altair EmployeeGood evening,
I am working on my aerospace engineering final project consisting of a flight control system. As you can see from the picture attached, I am using motionview to model a series of rods connected with several joints.
My teacher asked me to write a script to make hyperworks automatically analize rod's stability. In particular, the following expression should not exceed a known value:
F = (pi)^2 E I /(L^2)
where 'L' is the lenght of the singular rod and 'I' is the minimum moment of inertia.
To sum up, I need motionview to read the lenght and the moment of inertia of each rod and to check the value of 'F'
This is the first time I use motionview for this scop so I don't really know what I should do.
I would be greatful if anyone could help me
thank you in advance for your help

Hi @s211878
Can you explain what do you mean by reading length and MI?
If you have CAD geometry, MV will calculate MI within MV.
Do you need a script when used should ask for these parameters (pi)^2 E I /(L^2) and calculate F?
Good morning and thank you for your answer
I need a script to calculate F for each rod modeled in motionview
the script should:
1. calculate MI and length of the rods
2. calculate F for each rod (or at least for the longest rod)
3. check if F is greater then a given value (or simply display F)
I apologize if this is not clear
thank you for your help
