implementing 'simply supported'

[nordica]

simple question from a new user of workbench 9.0:

i have a beam i want to put in compression, with ends free to rotate as the beam curves (buckles) in compression. i think this should be 'simply supported'.

but the 'simply supported' button is grey when 'environment' is highlighted in the outline.

how can i implement the supports i need?

thank you!

If you know your boundary conditions should be "simply supported" just implement these in the model manually using fixed displacements.

Hai,

Using given displacments option in Ansys-WB

if i use 'given displacements', i can set 2 of the 3 axes to be zero, and let the third axis (along which buckling occurs) stay free to move. however, non-zero given displacements are not allowed in a buckling analysis.

is there some way to get around this? or a different type of support to use?

thank you
