Hi everyone, I'm make result for hexa element structure

I want to show reaction force on arbitrary node but impossible.

Please teach me about this

    Do you have Reaction code within Hyperview? If not you have to active in output block.

    In Hyperview just choose 'Vector' and your nodes to show.

    Dear @Q.Nguyen-Dai

    In my HyperView, not have Reaction code (only have Displacement and Stress 2D/3D). Please teach me make it \

    If you use Optistruct, have a look at:

    dear @Q.Nguyen-Dai

    Thank you so much.

    I also want to ask difference between GPforce and SPCforce?

    Can you explain a little about this for me?

    Best Regard

    SPC forces are reaction force, and available only where you have any constraints in your model, or enforced displacements.

     

    GPForces stands for grid point forces, which are the forces in the nodes of your model, that are used to perform Free Body Diagrams in your model, and can be computed anywhere in your model.

    Hi @Q.Nguyen-Dai and @Adriano A. Koga

    About Reaction Force of SPC, I finished it. :)/emoticons/default_smile.png' srcset='/emoticons/smile@2x.png 2x' title=':)' width='20' />

    But about displacement of 'applied force point', is It belong to GP (Post >> Free Body >> Displacement) or not?

    I think It will be exported by displacement of node. Because when I use 'Post >> Free Body >> Displacement', I don't find loadstep !!

    Thank you so much
