Dear all,
I have a solid body within pipe flow and I am interested in determining the lift and drag coefficient of the solid body. These coefficients are determined using the drag and lift forces, so actually I want to determine those!
As a solver I use the IBcfdemsolver (as I include big particles).
Resulting from this I have dump files from LIGGGHTS and vtk files from OPENFOAM, which I analyze using Paraview. The dump files include location, radius and velocities of and, forces on the big particle. I was hoping these forces would suffice as drag and lift forces, but they are (by far) too small to be realistic and hence, I doubt the relevance of them.
So my question is, how can I (probably using Paraview) calculate the lift and drag forces on my particle? Or is there an other method to compute these values within my OPENFOAM or LIGGGHTS code?
Attached are my CFD and DEM files.
Regards,
Boris
