Motionview Flexible model

Altair Forum User

I have a MBD model with a flexible body. When I open Hypergraph for post-processing, there is 'Flex_body/30116' in the Y Type. How can I know what the Y component (X, Y, Z, E0, E1,..., Q/7, Q/8, ..., SE, etc.) refer to ?? I am not able to find it in the documentation of motionview or in hypergraph.

 

Thank you.

Hi Benjamin,

MotionSolve post processing details are available in the Help Menu - Visualizing Results - Animation and Request Plotting.

Please find the image along.

Thank you. Can you give me more details about how the Q/i (modal participation factor) is calculated ? 

 

Normally, I suppose that I should have a sum of modal participation factors as close to 100 % as possible?

 

Which parameters affect the most this participation factor ? I am trying to increase them.

I have found that SE is the strain energy. Is it the total strain energy ? Does it refer to all the energy inside my flexible model when it is deformed ?

thank you,

Hi Benjamin,

 

Are you referring to elemental strain energy?

This is my question. When using Hypergraph with my flexible multibody result, there is a variable name SE in my Flex_body/i of my readed .abf file (example flex_body/30116). I am not sure if its the total strain energy of my flexible model, the elemental strain energy or the strain energy density ?

thank you

Hi,

 

It is the strain energy in the flexbody.
