Here only the Slice and Warp filters will be discussed. To modify the base data or geometry imported from FEM Workbench, filters can be applied. The default number of ranges is 256, but here the number is set at 10.Īpplying Filters to FEM Workbench results The setting for Color Discretization is useful to limit the number of iso values, thus creating more practical ranges for design. The coloring of the iso map can be controlled through the Color Map Editor, which is activated by pressing the Edit button on the Properties Tab: This opens the following window for the color legend settings The Color Legend can be dragged around the screen to a more convenient location and will change orientation when nearing any of the windows edges.Īlternatively, the settings of the color legend can be controlled in great detail by opening the Edit Color Legend Properties dialogue from the Properties Tab (press last Icon to the right) The RenderView window will now show an iso-plot of the selected data type and a Color Legend of the data range. The default is Solid Color, but the drop down menu shows all the scalar data that is available in the imported VTK file.įor the purpose of this tutorial we choose ReinforcementRatio_x, but it is easy to change to any data type. For this we need to change the Coloring option. For now we will only use the Surface or Wireframe option. This is done on the Representation drop down menu. The first setting that we can change is the way data is presented on the geometry. To make sure all settings are visible and aligned with this tutorial press the Advanced Settings button (the gear wheel icon on the below picture). The selections and settings for displaying this VTK object can now be found on the Properties Tab. Finally, we will use the calculator and integration filters to derive new results by combining base import data.Īs the pipeline browser can contain several VTK objects and filter objects, first confirm that the right VTK object is highlighted in the pipeline browser. We will first have a look at displaying base import data on the original geometry and thereafter see how to apply filters to modify the geometry. Paraview has many options and settings for displaying results. In this way, data from different FEM Workbench analyses can be displayed in exactly the same way, without any additional effort. This prompts the user to specify a VTK file, which means that the actions performed in the last session can also be applied to a new VTK file. To continue where you left off in the previous session use File > Load State. NOTE: there will be no warning when leaving Paraview to save the state and all work may be lost when exiting the program. Therefore, to save your work use menu option File > Save State. Rather than saving data, Paraview stores the status (state) of the actions performed on the imported VTK object. To get a predictable rotation hold the X, Y or Z key while dragging the mouse with left mouse button pressed to rotate the model around the X, Y or Z axis, respectively The left mouse button makes the geometry swivel, but unfortunately in a difficult-to-control way (compared to FreeCAD). The gray geometry can be inspected by rotating the view. By default, this will show a top view (looking down along z-axis) of the geometry. Use menu option File > Open > *.vtk to open the VTK file that was generated with FEM Workbench. This is where the imported VTK data objects and applied filter objects (for geometry or data) will be visible. The start-up screen shows an empty Pipeline Browser. Next, use menu option File > Export > FEM result VTK (*.vtk *.vtu) to export the VTK data. In FEM workbench highlight the CCX_Results object. The FreeCAD files used for this tutorial available in this and this FC forum thread.This tutorial is based on version Paraview 5.8.0 for Windows, which was the most recent version at the time of writing the tutorial.Paraview downloaded directly from it's website or your preferred package manager.FreeCAD using a version that is compatible with the designated version of this Tutorial.This tutorial explains the basics of transferring data from FEM Workbench to PV and shows some of the options and settings for displaying data. Some forum posts and tutorials use Paraview (PV) to review and analyse FreeCAD FEM Workbench results. Post-Processing of FEM Results with ParaViewīeam and wall found in this FC forum thread
