beam buckling

Please login with a confirmed email address before reporting spam

I have a question about beam buckling.

As shown in attached picture, it is a beam pined-pined at both end. An axial force is applied along the centroidal axis and the equation for the beam is d2 v/dx2 +A^2 v = 0. The boundary condition at the left end is pined but free to move along the centroidal axis. My question is how to model this boundary condtion in COMSOL.
Please give me some suggestions about it.
If anyone can give me a COMSOL model file with this problem, that would be very appriciated.
Thank you very much in advance for any help.
