Comments

  1. It is not possible to have several times the same node in the same /TH/NODE group. Radioss Starter gives an error message in such a case. In order to have several outputs on the same node, in different skew systems use several /TH/NODE groups.
  2. 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 variables groups are listed. If a variable group is requested, all the associated TH-variables are written at once.

  3. If a skew system is specified, coordinates, displacement, linear and angular velocities, linear and angular accelerations of the node with respect to the global system are projected onto the skew system.
  4. If a reference frame is specified, the local coordinates, relative displacement, relative linear and angular velocities, relative linear and angular accelerations of the node with respect to the frame are output.
  5. The reaction forces REACX, REACY, and REACZ and the reaction moments REACXX, REACYY, and REACZZ are output for nodes where imposed velocities, displacements, accelerations and boundary conditions are applied.
  6. DRX, DRY, and DRZ Output are available only for the nodes having rotational degree-of-freedom (e.g. nodes belonging to a shell element). Rotation is output in radian and represents rotation of the node around corresponding global axis passing through actual node position. For secondary nodes of rigid body, the output gives rotation of the main node around corresponding global axis passing through actual main node position.
  7. DX_iii, DY_iii, and DZ_iii are only available for plyxfem formulation.
