Hey guys,

 

I'm applying a force in the Z-axis direction but it's coming up the wrong way, is there a way to change the direction? (down rather than up?)

 

 

Thanks in advance

    Just change the sign : if the current value is positif, change to negatif value.

    If it is Hypermesh Radioss user profile.Then reversing load direction is issue.Even though if you give - sign it wont reverse load (Display)

    Hypercrash would work fine for such instance.

    Hi,

     

    I'm using Optistruct and working on a flat 2D model. I'm trying to change the direction of the force from underneath to above. I can't see the sign you speak of.

     

     

    Thanks
