Particles constricted to quadrant of insertion region defined

Submitted by dhari27 on Wed, 08/12/2015 - 16:41

Hi everyone,

After running my program with insert/pack, in the visualisation majority of the particles tend to stick to quadrant region out of the total insertion region defined. I haven't been able to debug the mistake.

Can anyone help me?

I am attaching the input file and log file along with the pics of the result.

Regards
Hari

Hi,

Your global bounding box only spans that one quadrant during the first time step. Your cylinder axis is at (0,0) with a radius of 3e-3. Your box only spans from (0,0) to (3e-3, 3e-3). After the first timestep the bounding box expands as the particles move beyond the bounding box (thanks to "boundary m m m")
Solution: make the bounding box large enough to contain the insertion cylinder.
region domain block -3e-03 3e-03 -3e-03 3e-03 0. 0.010 units box

Cheers,
Richard

Thanks Richard for your comment. I changed the domain values accordingly and got the particles to deposit in the whole area.
