What are the types (variable and degree of freedom and polynomial orders) of Comsol truss rod column and beams elements?

Hi,

The Truss elements use Lagrange shape functions of order 1 to 5.

The Beam elements use Hermitian shape functions for the bending (with possible Timoshenko correction). For tension and torsion, linear Lagrange shape functions are used.

Henrik
