Hi. I want to plot maximum principle stress, elastic strain energy and signed von-mises contours for Tetra4 meshed components. Which card should I use?

 

Regards,

Rachit

    I don't know about ESE

    For the priniciples and signed von mises you can request:

     

    /ANIM/BRICK/TENS/STRESS/ALL

    /ANIM/BRICK/TENS/STRAIN/ALL

    with an /ANIM/DT card

    if you are using /ANIM output

    or

    /H3D/SOLID/TENS/STRESS

    /H3D/SOLID/TENS/STRAIN

    with an /H3D/DT

    if you are using /H3D output

    Hello Paul. Thanks for your reply. But I am still not able to get principle stresses. Maybe the above card works for brick elements only.

    Are you looking under the correct entry? 'Strs Intg Point111' if you are using Anim file (it will be separate to 'Stress' if you are still asking for 'ELEM' stress too. It should definitely be working for Tetras

    Hi Paul. Thanks for your reply. Yes you are correct, 'Strs Intg Point111' entry has stress values.

    For ESE, we may use /Anim/Elem/EINT. It gives internal energy, which should be same as strain energy.
