The 'play' button will display the individual images in their sequence. With the recorder-like icons on the top, we can move through all the individual results that were created during the analysis. Via the little icon with a heart, we select the color scale 'cool to warm'. Since ParaView offers a lot of possibilities, please refer to the appropriate documentations around the internet.įor demonstrating purposes, let us now visualise the temperature of the bent bimetal strip: In the 'properties' tab on the left, under 'coloring' we select temperature, and the image gets color-mapped according to the local temperature. (Of course, it always makes sense to check if the times given here are correct or if something strange happened during the export.) From here, we can use ParaView to play around with the results.
In the 'Information' tab we will see a list of Index and Value, corresponding to the timestamps of the results that we just imported.
In the 'Properties' tab, we click 'Apply' to load the results. Now, we open ParaView and go to File → Open. pvd file is created, which tells ParaView which result set belongs to which timestamp. vtu files, one for each result set for each timestamp. (Note: Sometimes messages like 'PropertyFloatList NOT exported to vtk' appear, but I was able to work with the VTK files anyway.) In the subfolder 'vtk-export', we will find. In the Report View (View → Report View), we should see 'Macro finished', if eveything went fine - or some error messages. Depending on the number and size of the result objects, this may take some time. The macro will now create a subfolder 'vtk-export' besides the. With the example file opened, we go to Macro → Macros., select "ExportTransientResults_190830.FCMacro" (or whatever name you saved it as) and execute it. Save the FCMacro file in the FreeCAD macro folder, which can be found via Edit → Preferences → General → Macro.

A step-by-step guide to create the sample file is given here, or you can download the file from the downloads section of this page. pvu file that can be opened from ParaView.Īs an example, the bending of a aluminium/steel bimetal strip is used. FCStd file, a new folder 'vtk-export' will be created, containing the individual results (.vtu files), and a. Run the macro on a FreeCAD project that includes several FEM result objects from a transient analysis. Unfortunately, the FEM workbench doesn't support the export of multiple.
vtu file, which can then be opened with ParaView. You can export single FEM result objects from FreeCAD as a. A better tool for post-processing and visualisation is ParaView. However, the possibilities within FreeCAD are still limited, especially for transient analyses. The individual results can be investigated directly in FreeCAD and be post-processed using pipelines. This macro exports multiple FEM result objects from a transient analysis to the VTK format and generates a PVU file which can be used to load the results directly into ParaView for post-processing.Ī transient analysis in FreeCAD ends up with a bunch of FEM result objects, one for each timestamp.
