Thanks.

Hi,

please find enclosed simple example - cantilever loaded by two forces at the end. This is a very raw model, just illustrating the basic use of the element, do not expect good results as this element has only linear approximation of displacements and thus internal forces are constant along the individual elements.

The meaning of generalized strain vector, as reported in output file is following:
{eps_x,eps_y,eps_z,gamma_yz,gamma_zx,gamma_xy, kappa_x,kappa_y,kappa_z,kappa_yz,kappa_xz,kappa_xy},

where (if we are in local coordinate system (element is in xy plane)):
- eps_x, eps_y, gamma_xy - membrane components
- gamma_yz, gamma_zx - shear strains
- kappa_x, kappa_y, kappa_z, kappa_yz, kappa_xz, kappa_xy - pseudo-curvatures, associated to bending moments (m_x, m_y, m_z, etc).

The meaning of internal forces vector components is analogous. All internal forces are per unit length.
