Print primary unknown field in node_dof into the file tecplot.plt if switch is set to -yes. Also results of node_dof_calcul records (if present) are printed in the tecplot.plt file.
If switch is set to -mesh, then also the mesh is printed; this will be done automatically however for a new mesh or if the mesh has been changed.
As a special option, you can specify the number of an eigen mode instead of -yes after materi_velocity has been initialized and an eigenvalue analysis has been performed by control_eigen. Then the eigenmode for the velocity is added to the nodal coordinates. In this way you can view the mode.
