Output for Section

  • WORK: work of the forces and moments in the section, due to elements and interfaces saved in the section
  • DFX - FX error: Errors in forces in the component section
  • DFY - FY error: Errors in forces in the component section
  • DFZ - FZ error: Errors in forces in the component section
  • DF2: quadratic error on forces in the component section
    ( Δ F x 2 + Δ F y 2 + Δ F z 2 )

    all nodes of the cut section

  • WORKR: work of the moments in the section, due to elements and interfaces saves in the section
  • DMX - MX error: Errors in moments in the component section
  • DMY - MY error: Errors in moments in the component section
  • DMZ - MZ error: Errors in moments in the component section
  • DM2: quadratic error on moments in the component section ( Δ M x 2 + Δ M y 2 + Δ M z 2 )

    all nodes of the cut section

  • KIN: translational kinetic energy (section nodes)
  • KINR: rotational kinetic energy (section nodes)

    (Be aware that if you compare these values of the component model with those of the full model, it will be different because the nodal masses are different.)

  • DMVX - MVX error: Errors in the translational velocities
  • DMVY - MVY error: Errors in the translational velocities
  • DMVZ - MVZ error: Errors in the translational velocities
  • DMV2: Error translational kinetic energy
  • DMV/RX - MVRX error: Errors in the rotational velocities
  • DMVRY - MVRY error: Errors in the rotational velocities
  • DMVRZ - MVRZ error: Errors in the rotational velocities
  • DMVR2: error rotational kinetic energy
  • EFW: external work of the component section. This is equal to the global external work if there is no other external work (due to another cut section, rigid wall friction, imposed velocities). It is equal to WORK with the difference of the inertia work force.

    EFW = WORK - KIN ENERGY

  • FNX: normal force in direction X of global axis
  • FNY: normal force in direction Y of global axis
  • FNZ: normal force in direction Z of global axis
  • FTX: tangent force in direction X of global axis
  • FTY: tangent force in direction Y of global axis
  • FTZ: tangent force in direction Z of global axis
  • MX: Moment in direction X of global axis
  • MY: Moment in direction Y of global axis
  • MZ: Moment in direction Z of global axis
  • F1: Force in direction 1 of local axis
  • F2: Force in direction 2 of local axis
  • F3: Force in direction 3 of local axis
  • M1: Moment in direction 1 of local axis
  • M2: Moment in direction 2 of local axis
  • M3: Moment in direction 3 of local axis
  • CX: Coordinates of center of section in direction X of global axis
  • CY: Coordinates of center of section in direction Y of global axis
  • CZ: Coordinates of center of section in direction Z of global axis

Comments

  1. Available names are listed in the two tables above.

    In the first table, TH-variables are listed. If a TH-variable is requested, this variable is written.

    In the second table, other variable groups are listed. If a variable group is requested, all the associated TH-variables are written at once.

  2. The output of section force/moments errors works only for submodeling modelization, when ISAVE =2 is used in the full model and ISAVE =101 is used in the cut model.
