particles overflow the boundary of .stl file

ccciew

Why do the particles overflow the boundary of the .stl file when I do the 2D elbow-flow simulation?

My .xml file is as follow:

CaseFlowCylinder_Re020_Def.txt

Thanks a lot.

First you need to be sure that cs=15 m/s is big enough... since dt=h/cs

If that is not working then you have to create more layers of boundary particles in your pipe
