Notes

  1. Surveys allow the evaluation of the spatial distribution of various quantities relating to specific elements of the model. These various quantities are evaluated after the entire simulation is completed and the results are plotted to illustrate the simulation. Plots of the survey outputs will be generated, if requested by the plotting control parameters.
    • Within Dymore, the plots associated with a survey are two-dimensional graphs: space is plotted along the x-axis and one or more of the quantities evaluated by the survey are plotted along the y-axis.
    • Within NormalBuilder, the plots associated with a survey are two-dimensional graphs: stress or strain distributions are plotted along the x-axis and the lay-up through-the-thickness coordinate is plotted along the y-axis.
  2. The quantities to be evaluated by the survey are defined by four input parameters.
    • The ObjectName indicates the object to be surveyed.
    • The SurveyType determines the nature of the quantities to be evaluated.
    • The FrameName specifies the frame in which the quantity is measured.
    • Within Dymore, quantity t specifies the instant in time when the survey is to be determined. Within NormalBuilder, stress resultant StrResName must be specified.
  3. Within Dymore, surveys can be defined for beams, cables, and lifting lines. Within NormalBuilder, surveys can be defined for lay-ups.
  4. The SurveyType determines the nature of the quantities to be evaluated. Refer to the specific object to find the list of supported SurveyType.
  5. The FrameName specifies the frame in which the quantities are measured. Refer to the specific object to find the list of supported FrameName. The following FrameName can be specified
    • INERTIAL: the quantities are measured in the inertial frame.
    • LOCAL: the quantities are measured in a local frame of reference. Note that this option is not valid for all SurveyType.
    • FrameName: the quantities will be measured in a previously defined frame FrameName that can be either a fixed frame or a moving frame.
  6. Within Dymore, the value t specifies the instant in time when quantities will be evaluated.
  7. Within NormalBuilder, stress resultant StrResName defines the loading applied to the lay-up.
  8. If the output of the survey involves rotations at a node, the parameter RotationRep can be used to select a specific way to represent rotations.
  9. It is possible to attach comments to the definition of the object; these comments have no effect on its definition.
