Hello,

I am doing a DPM. I used "group" injection. But when I entered the required fields, the positions of first and last point are inside the region of my model. Why is it that after iteration, and display -particle track, it says "unable to locate injection-0" and the number tracked is 0.

There is no problem when I used surface injection.

Your starting location for your group may lie right on the boundary of you domain. Nudge it inside the domain slightly and see if that changings things.

Hi, try 1 of the 2 alternative below: 1:think to set the injection point location "enough" farmer from the domain boundaries. 2: decrease the nombre of particle streams good luck
