Hello all,
Im working on gas-solid fluidized bed. column size is 0.11m*0.11m*1 m. I have packed the column with 10000 particles of 6 mm size and 2600 kg/m3 density but when i visualize it in paraview i found that x and y bounds of the packing are coming very less. x and y range<< 0.11m and also insertion region is coming very small as given in the script ( attached file in. txt). Is there any problem with the boundaries or simulation box?? As given in hopperemptying example i made 3 input script files ( attached files in.txt, in_DEM.txt, in_couple.txt) accordingly and executed it with the following series of commands:
cd ../../DEM
liggghts < in.pramod (this generated a liggghts.restart file)
cd post
pizzaScriptInit (with dump.pramod)
ctrl d and visualization with paraview
cd ../DEM
liggghts < in.pramod_DEM (this generated dump.pramod_DEM in post directory)
cd ../CFD
blockMesh
checkMesh
decomposePar
mpirun -np 2 cfdemSolverPiso_shared -parallel (coupling of openfoam with in.pramod_couple liggghts file- this generated dump.pramod_restart in post directory)
reconstructPar
foamToVTK
cd ../DEM
pizza -f pizzaScriptRestart
ctrl d and visualization with paraview
Problem is that, im not able to see the solid phase in paraview after 1 sec of simulation.Are the commands given correct step by step or im missing anything?? please find the attached input script liggghts files.
I am struggling with this problem from past 2 weeks. Any suggestions regarding this problem will be appreciated

Hi,
is it probably just a visualization error? Older pizza versions had this issue with the scale command?
If you do not see the voidfraction in the CFD domain change due to the particles, the CFD and DEM domain might not fit together?
Cheers,
