resetEstrucDatosDiagrama()

Diagram control variables

Display of diagrams (forces, moments, …) on linear elements

class postprocess.xcVtk.diagrams.control_var_diagram.ControlVarDiagram(scaleFactor, fUnitConv, sets, attributeName, component)

Bases: postprocess.xcVtk.diagrams.colored_diagram.ColoredDiagram

Diagram of control var values (capacity factor values, internal forces values (N,My,Mz,T,Vy,Vz), crack width values,…

Variables:
  • scaleFactor – scale factor for the diagram (can be negative too).
  • fUnitConv – unit conversion factor (i.e N->kN => fUnitConv= 1e-3).
  • sets – list of element sets for which the diagram will be displayed.
  • component – property to be displayed (possible arguments: ‘CF’, ‘N’, ‘My’, ‘Mz’, ‘wk’,…)
Parameters:

attributeName – name of the element’s property that has the control var in it for example as in elem.getProp(attributeName).component.
addDiagram()

Add diagram to the scene

getElementComponentData(elem)

Return the data to use to represent the diagram over the element

Parameters:
  • elem – element to deal with.
  • component – component to show. Valid components are: ‘N’, ‘Qy’, ‘Vy’, ‘Qz’, ‘Vz’, ‘My’, ‘Mz’, ‘T’
getMaxAbsComp()

Return the maximum absolute value of the component. It is used only for calculating auto-scale parameter, so we compare only values of the component in first node of the elements
