Hello community,
I am working on my Master Thesis in the form of a continuous mixer, I am currently in the process of determining the parameters inside the cylinder and it is set as a residence time of particles in the simulation domain as one of the main factors.
According to the documentation, such an approach has already been given as a ready-made function:
https://www.cfdem.com/media/DEM/docu/fix_property_atom_region_tracer_tim...
But I have problems with value output.
The current approach is:
.......
region measureCylinderRegion cylinder y 0 0 0.13 -0.35 0.485 units box
fix tracer all property / atom / regiontracer / time add_region measureCylinderRegion check_region_every 100
variable rt equal f_tracer
fix output all print $ {dumpstep} "$ {dumpstep}, $ {rt}" screen no file rt.csv
...........
It gives out empty csv file.
Every hint is welcome.
Best regards,
Tomislav
