Hello, I am running a simulation with hoomd v3.1 and I am facing issue with simulation accelerating.
I am currently running a poiseuille flow between two walls. The box size is 300x30x30 (x y z). Initially I charge the particle and use the hoomd.md.external.field.Electric() to impose body force.
Simulation typically do not accelerate for F=0.001 and 0.002 but things starts to accelerate at F=0.003. I am imposing different attraction strength for colloid-colloid and colloid-wall. Typically, for colloid-colloid of D0=6kT it shows acceleration no matter what the colloid-wall interaction is. However for colloid-colloid of D0=12kT colloid-wall D0=12kT, it was not accelerating. (but with colloid-colloid of D=12kT and colloid-wall D0=6kT, the simulation plateau for some period of time and start accelerating again.)
I cannot seem to solve this issue.
Below I have attached the plots of <average velocity in flow direction >vs <time> and python simulation code.
Any suggestion to resolve this issue is greatly appreciate it.
