Deflection of a beam using beam module

Hello,

I am a new to the software and recently started doing my work in it and started to face an issue while modelling a beam using the beam module. to start with, I selected my dimension to be 3D and later selected the "Beam" in "physics" category and "stationary" in "study" category. I started creating the geometry and selected the "block" and entered the dimensions which I had. Then I assinged the material to the domain. After this step, I was instructed to assign the edges with the material rather than considering the whole block as one. Secondly, When I went tothe "Beam" physics, I had to apply a pressure to one of the faces of the beam, but the "Beam" phyics only allows me add edge load and point load. How can I add a pressure to one of the faces of the beam using beam module?

Thanks in advance,

Regards, Shashank

Hi Shashank,

The Beam interface is used for modeling slender structural elements having a significant bending stiffness. Beams can be modeled on 2D boundaries and 3D edges, and you should then not add any solid 3D geometry objects when modeling the beam structure. If you want to model a beam in full 3D, use the Solid Mechanics interface instead.

Best regards,

Magnus
