Modal Strain Energy output request won't get printed in the h3d output file

Dear all,

 

I am trying to output modal strain energy for a component. Despite having followed the manual carefully, I am still unable to see modal strain energy results in the h3d file when I view it on Hyperview. Though I can't share my model files due to privacy, below images show the settings I use for the load step. I also show the mode set settings, as I intend to output modal strain energy only for the first mode.

 

What I basically do is I define a load step of the type freq. resp (modal) with a method (struct) that is EIGRL (the first 15 modes, excluding rigid body modes). No spc. Analysis type set to MODES. For OUTPUT, I select only MODALSE. Please see below images for details on the settings I am using.

 

I have also tried adding an OUTPUT control card with settings H3D, ALL, BYITER. Unfortunately, I was still unable to print modal strain energy results in the result file.

 

I would appreciate any information on how I can print modal strain energy values in the result file.

 

Best regards,

 

Deniz Bilgili

 

Note: I am using Hyperworks 17

    Hi,

     

    Are you running Modal frequency analysis?

     

    MODALSE works only with modal frequency response analysis.

    Hello Prakash,

     

    Yes, I am running frequency response analysis. As you can see in the first image I have provided in my first post, my subcase's analysis type is set to 'Freq. resp. (modal)'.

     

    Kind regards

    Hi,

     

    Can you update to 2017.1?

     

    I am able to see element strain energy (MODALSE) with this.

    Hello Prakash,

     

    Sorry for the late response. I'll need to speak with the IT department to see if they can update my Hyperworks softwares to version 2017.1. It is good news that it's possible to output MODALSE in 2017.1. I will check back in with you when I test it out myself.

     

    Thank you for your time and help,

     

    Best regards
