The code for the 3d cantilever beam using solid elements is shown below. from dolfin import * L = 5000. H = 600. W = 300.0 mesh = BoxMesh(Point(0, 0, 0), Point(6, 2, 1), Nx, Ny, Nz) E = Constant(1e5) nu = Constant(0.3) mu = E/2/(1+nu) lmbda = E*nu/(1+nu)/(1-2*nu) def eps(u): return sym(grad(u)…

When you say beam-element do you mean a hexahedral cell? This is supported in for instance DOLFINx. [image] GitHub - FEniCS/dolfinx: Next generation FEniCS problem solving environment Next generation FEniCS problem solving environment - GitHub - FEniCS/dolfinx: Next generation FEniCS p…

A beam element has 6 DoF’s per node. 3 displacements and 3 rotations. [image (10)] [initial]

Could you send a formal definition, along the lines of: DefElement An encyclopedia of finite element definitions as I’m not familar with how you define these degrees of freedom and corresponding functionals.

As far as I can understand from discussions with co-workers, you just want to use a first order vector Lagrange element on a hexahedral grid.

Hi, were you able to model the beam with beam-element ? I am trying similar problem. I am looking for suggestions.

I found one old post(link) regarding beam elements. @bleyerj had suggested this tutorial . I want a similar study using 3D beam elements for a 3D cantilever beam problem.
