/fixes

  • fem::numerical_model_base::set_hard_offsets on 3-node non-linear elements
    (fem::model_beam_gnl, fem::model_rod_gnl or fem::model_rod_gnl1):

    • Bug on the rotations of node #2 (the central node).
  • fem::Cauchy_stresses:
    • Bug for tapered beams.
  • fem::spring, fem::spring_directional, fem::pulley:

    • Wrong strain values in case of initial/thermal strains.
  • fem::model_shell_mass:
    • The perpendicular inertia was null.

  • fem::solver_heat_dynamic_linear:
    • Crash with data_type::outputs::get_state(i).
  • fem::solver_static_linear, fem::solver_heat_static_linear, fem::solver_buckling_Euler:
    • Crash with problems with no load case.
