Hi all,
I am using the the sample script lb_fluid_coupling_gpu.tcl
I
have modified the script to print the velocity each time the script
records for the average. I have also increased the integrations to 500
steps per recording.
When the force density ext_force $fdragx $fdragy $fdragz is
removed from the fluid, the particle accelerates beyond the expected
terminal velocity of 0.1, even beyond the allowance for effective
friction having a lower value lower than the bare friction (Alrich &
Dunweg 1999).
Why is a terminal velocity not achieved?
Thanks,
