In case of any issue, please, contact us at info@cfdsupport.com. Basic postprocessing As usual, visual postprocessing can be done in paraview.For visualization of particles topology inside the cyclone follow theses steps:Run paraview in case directory, i.e. use paraFoam command.Load the case, make just boundary visible (check only patches in Mesh parts).Make few clips to see just backward walls.Load the case again and visualize internalMesh only and alpha.particles volume field.Instead of surface representation use volume representation.For transient cases a time information is important; Go to menu Filter -> Alphabetical -> Annotate Time Filter.Final view is depicted in Figure Figure: Alpha.particles visualization. It is possible to evaluate any field which given solver uses at any patch directly. It can be performed with patchAverage utility.Moreover, using foamCalc utility, it is possible to create new field e.g. magnitude of U, components of U (i.e. Ux, Uy, Uz),…To evaluate velocity magnitude at the outlet do following steps:First, create field magU: # mpiexec -np 4 foamCalc mag U -parallelSecond, compute average value at the outlet patch: # mpiexec -np 4 patchAverage magU Cyclone-outlet -parallelFor each saved time it prints the average volume of velocity magnitude directly on screen .
