1.4  Database nodes : structures used for typical data

The SDT supports a number of database nodes used to store common structures. The currently identified list is obtained using sdtm.nodeDtype.

• model for
  • model FEM models with properties allowing to run a FE simulation
  • wire frame displays use the same structure to define the geometry (they lack material properties, ... present in FEM) but use a sens.tdof field to define sensors.
  • Topology correlation results generated by dockCoTopo , are also wire frame displays with additional information.
• Responses can be defined at
  • DOF , see def
  • .tdof sensors (when dealing with input/output separation in id_rm).
  • .dof input output pairs when using measurements associating both an input and an output
  • Identification result at .dof
• curve for multi-dimensional data. This is typically used for
  • transfers xf Response data Multi-dim curve
  • Time data
• sens sensor definition, see section 4.8.
• Identification result Shapes at IO pairs, see .dof
• Shape at sensors, see .tdof
