If I have understood correctly, you say that I should double integrate the differential equation to find u(x), right? What if I don't know this differential equation? Is it possible to find it somewhere or deduce it?
Thank you and sorry...

Could you explain me how to do so? I have been looking up in the manual but I cannot find other than the display command. I have been using it but only straight lines appear and I would like a more accurate deformed shape.
Thank you.

Ok, so the only way of knowing a more approximate deformed shape of a structure would be creating intermediate nodes and elements?

Sorry, I meant an elasticBeamColumn element. Is there a possibility of using several integration points?

Hi all, just a little question. Is it possible to use several integration points with an elastic material?
If it is possible, how? I can't find it in the manual. If not, why?
Thank you.

Dear all, I have a little problem when I try to model this distributed load. I know that a vertical distributed load "w" on a beam which length is "L" can be modelled with the eleLoad command or with its equivalent (2 vertical loads wL/2 and 2 bending moments wL^2/12 on the end n...
