Particle tracer of transient CFD datasets

Hi, I am trying to load multiple ansys Fluent output datafiles of cgns format, the solution is transient and exported every timestep. The files are loaded into Paraview as multiple groups of cgns files, but failed to generate particle tracers, I followed the example here [ParaView Postprocessing 13] Fluid flow: particle tracking and path lines - YouTube and many other tutorials, however, I received the following error:

Warning: In C:\glr\builds\paraview\paraview-ci\build\superbuild\paraview\src\VTK\Filters\FlowPaths\vtkParticleTracerBase.cxx, line 719
vtkParticleTracer (000002A40D100F50): Multiple inputs founds. Use only the first one.

Also, for creating contours, vectors and streamlines, I can only generate this for one group of cgns files only and repeat the process for the other group of files one by one, which is not feasible for a large volume of data files.

Could you please help in these two matters?


Are you looking to merge or group files together ?

Use GroupDataSets or AppendDataSets

Hi, thank you for your reply.

That’s exactly what I wanted!
