One direction (+Z axis ) SPC constraint

Hakan Sezen

Hello, 

I am using Hypermesh 2021 version. I couldn't determine only positive or negative direction constraint on my model. which tool I should use for that constraint which I describe just +Z direction SPC constraint not -Z direction ?

Thanks.

Hello,

Personally I have created this behavior in Optistruct by using gap elements or contact.
One specific contact with might work very well for this is Fast Contact.
