12.4 Nodal Output

Nodal output values are written to the file <name>.nodeout.txt. Following data items are given, each line-wise with white-space delimiters:

• Instant of time with

  • time-value

• Data at nodes – sub-items in one line

  • node number

  • coordinates

  • displacements corresponding to nodal degrees of freedom, e.g. in case of plates, in case of 2D-beams, in case of shells

    • i.e. the number of values varies according to the type of freedom, see also Section 1

  • internal nodal forces corresponding to nodal degrees of freedom, i.e. the same number of values as for displacements

    • internal nodal forces with absolute values smaller than roughly (depends on prescribed equilibrium tolerance , see Section ) may be considered as equilibrated

    • larger values (absolute) occur with prescribed degrees of freedom and correspond to boundary reactions

  • output for nodes of slab elements (SB3) partially differs
    integration point moments projected to nodes are inserted between displacements and internal nodal forces

    i.e. Node x        y        z       w           phi_x       phi_y         m_x         m_y         m_xy          f_w         f_phi_x     f_phi_y
    

Output is repeated for each interval as defined by step sub-keyword *NODE FILE, see Section 10.9

Nodal output values are also written to the file <name>.nodeout_.txt. Specifications remain to be appended.
