7.8  FEM result data structure

Deformations resulting from finite element computations (fe_eig, fe_load, …) are described by def structures with fields


.defdeformations (NDOF by NDef matrix)
.DOFDOF definition vector
.data(optional) (NDef by Ninfo vector or matrix) characterizing the content of each deformation (frequency, time step, ...)
  
.funfunction description [Model Analysis Field FieldType Format NDV]. This is based on the UNV 55 format detailed below. Typically field with [0 fe_curve('TypeAnalysis')]. This field is needed for proper automated display setup.
.lab(optional) cell array of strings characterizing the content of each deformation (columns of .def). For large arrays, the use of a .LabFcn is preferrable.
.LabFcn(optional) string to be interpreted defining the label of each channel using local variable ch (number of the channel currently displayed in feplot). For example 'sprintf(''t=%.2f ms'',def.data(ch)*1000)'
.label(optional) string describing the content
.DofLaboptional cell array of strings specifying a label for each DOF. This is used for display in iiplot.
  
.scalefield used by feplot to store scaling information.

The .fun field is a numeric row with values (a typical value for static responses is def.fun=[0 1 0])

SDT provides a number of utilities to manipulate deformation structures. In particular you should use
