Hello,

 

I have created a mesh file in HM and assigned material and properties to the elements.

 

But when I export the same file, I am not able to see the properties or materials in LS dyna.

 

May I know where am I going wrong? (I have used LS- dyna as profile)

 

Thanks

Bharat Hiranwale

    Could you please let us know the version & patch you are using at your end? I assume you would have checked appropriate comments option while exporting LS dyna file.

    If you use LS Dyna profile you should select Card image (Generally Part). Without this card image it wont take property or material whatever defined to that.

    Q.Nguyen-Dai - Sorry,can't share the model.

     

    Udhay - yes, I have done that.

     

    Rahul- Hyperworks 14 and LS dyna 7.0.

     

    Apart from the problem above, we are facing another issue. I have created all hex elements and assigned section property as thick shell in ls dyna profile. Whenever I import the file into LS dyna , the element normal for the same are not  uniform. In HM, I have extracted faces for the same and found the normal to be uniform. What might be the problem in LS dyna?

     

    Thanks and regards,

    Bharat
