FEM PostPipelineFromResult/it

Description

introduced in 1.1: The results pipeline can store results from multiple frames. To switch between the different frames, select them from the list.

Usage

If you see no model in the graphical area, go to and enable Edit → Preferences → Display → 3D View → Rendering → Backlight color.

If you use a SI-derived FreeCAD unit system, the values in the output scale are based on SI units as well. This means the displacement is in meter, the stress is in Pascal and the temperature is in Kelvin.

Data and extractions

introduced in 1.1: In the Data and extractions section, available also in the task panels of pipeline filters, multiple tools for simulation result data processing are available.

• The Data Summary button displays a table with min and max values of all output variables while the Show Data button displays a table with values of all output variables for all nodes. Thus, the table can be very large.
  • The Export to CSV button makes it possible to export the table to .csv file for external use.
  • The Copy selection to clipboard button (shortcut Ctrl+C) can be used to copy the table to clipboard.
• The New button allows adding new data objects to the Data and extractions tab based on FieldData (results from all nodes) or IndexOverFrames (results from node with a selected number):
  • New Lineplot - creates XY plot
    • with FieldData - X and Y axes can be configured to show any output variables, results are taken from all nodes
    • with IndexOverFrames - Y axis can be configured to show any output variable, X axis shows time/frequency (based on the frames), results are taken only from a node with a specified index (number)
  • New Histogram - creates histogram plot
    • with FieldData - uses selected output variable and results from all nodes
    • with IndexOverFrames - uses selected output variable and results from a node with a specified index (number)
  • New Table - creates a table
    • with FieldData - lists values of a selected output variable for all nodes
    • with IndexOverFrames - lists values of a selected output variable for a node with a specified index (number) in each frame
• The Add data to button adds data from the current filter to the selected existing data extraction object

Properties

Dialog box

This pipeline dialog box has the following settings:

• Mode: How to draw the results. The possible modes are
  • Outline: The outline of the result mesh. In fact, it displays no results but only the borders of the mesh.
  • Nodes: The result mesh nodes.
  • Surface: This is the default and displays the surface of the result mesh.
  • Surface with Edges: Like Surface but with the mesh outline edges and the surface mesh node connection lines.
• Field: Which result property to draw.
• Vector: Is only active if the Field is a vector. You can select whether to display the vector Magnitude or its X, Y, Z components.

Scale

If you double-click on the scale, you get this settings dialog box:

and you can modify these properties:

• Gradient: You can select reversed order of the default color gradient, Red-White-Blue, Black-White or White-Black.
• Style: The default option Flow uses the full color gradient range. The option Zero uses only the color gradient range starting form the color that would display the mean value to the maximum.
• Visibility: The option Out grayed will color all mesh nodes whose values are outside the set minimum/maximum range in gray. The option Out transparent will make these mesh nodes transparent.
• Parameter range: Minimum and maximum values are filled-in automatically. You can modify them, however make sure you know what you are doing. You can also change the number of displayed decimal places and the number of labels distributed over the parameter range.

Property Editor

In the property editor you can set in the View tab the settings from the dialog box. In the Data tab you can additionally set this:

• DatiMode: How the filters used in the pipeline will be treated. These modes are possible:
  • Serial: In this mode every filter takes the previous filter as input. The order is hereby the order of creation. The first created filter takes the pipeline as input. Its Input property is therefore empty.
  • Parallel: In this mode all filters take the pipeline as input.
  • Custom: This is the default and keeps the input of the filters as they are. Therefore it allows to have e.g. two filters that take the pipeline as input, and a third filter that takes one of the two filters as input.
