DPM injections
 

When i used "group" injections in DPM injection panel I got the message "lost 32 new injected particles on last node", I don't know what this means and how to solve it. My injection center point is (0,0,60) from center (0,0,0).

First point Last point
X position=-3.8 X position=3.8
Y position=-3.8 Y position=3.8
Z position=60 Z position=60

The upper inlet is 60 (positive z direction) from the center (0,0,0). The upper inlet circle's radius is 3.8 from where the particles are supposed to come. So from -3.8 to 3.8 in x and y direction the 100 particles would be injected (as the particle stream is 100).

Please tell me how to avoid this problem.
