How to display thermal gradients in Paraview

I am using the chtMultiRegionFoam solver to look at transient conduction through multi-phase systems. The simulations are running correctly and I am able to visualize the temperature maps using Paraview, however I would like to be able to see the thermal gradients as well.
When I apply the Gradient of Unstrcutred DataSet filter in Paraview I get the following error: Code:
ERROR: In C:\bbd\ecd3383f\build\superbuild\paraview\src\VTK\Filters\General\vtkGradientFilter.cxx, line 318 vtkGradientFilter (00000205FBC4A420): No input array. If this dataset is part of a composite dataset check to make sure that all non-empty blocks have this array. ERROR: In C:\bbd\ecd3383f\build\superbuild\paraview\src\VTK\Common\ExecutionModel\vtkExecutive.cxx, line 782 vtkPVCompositeDataPipeline (00000205F4C65220): Algorithm vtkGradientFilter(00000205FBC4A420) returned failure for request: vtkInformation (0000020592472820) Debug: Off Modified Time: 19414550 Reference Count: 1 Registered Events: (none) Request: REQUEST_DATA FROM_OUTPUT_PORT: 0 FORWARD_DIRECTION: 0 ALGORITHM_AFTER_FORWARD: 1 Code:

Have you tried the "Gradient Of Unstructured Data Set" filter in paraview?

Sorry, I think I was a bit too scatter brained when I replied!
It seems as though the parafoam doesn't have the temperature values everywhere that you are requesting. Maybe make sure that only the internal mesh is selected, and if you're doing a 2d simulation, take a slice of the domain? |
