Problem with particles' size in particle trajectory plot

Hi guys,

I am using particle trajectory module to launch few microbeads from the inlet of a microchannel towards its outlet. The problem is that in the model, I define particle's size as 10 um, but in the results section when I want to plot particle's trajectory they are shown much bigger! There is only one field called point radius expression with default value set to 0.001 um. But I could not figure out what does this filed do.

Unfortunately, Comsol's help for its particle tracing module is not very useful and informative.

Any idea about this issue is welcome. Thank you.

Best,
SMHH

Hi SMHH,
Could you attach a model? I'll take a look at it and see where the problem lies!
All the best,
Eyal
