satum

Hi I am running DPM simulation using KE model, segregated solver, two way coupled calculation and Stochastic model. I have set the Max no. of steps to 1000 and a length scale of 2cm. because the length of the domain is 20m.Also I have set the number of continious phase calculations per DPM to 10. I specify a 30 particles as a cone in the injections menu, however when I run fluent 6.1.26, in the console windowd displayed as follow: Unable to locate injection-0, number 8 Unable to locate injection-0, number 9 Unable to locate injection-0, number 10 Unable to locate injection-0, number 11 Unable to locate injection-0, number 12 Unable to locate injection-0, number 13 Unable to locate injection-0, number 14 Unable to locate injection-0, number 15 Unable to locate injection-0, number 16 Unable to locate injection-0, number 17 Unable to locate injection-0, number 18 Unable to locate injection-0, number 19 Unable to locate injection-0, number 20 Unable to locate injection-0, number 21 Unable to locate injection-0, number 22 Injecting 150 particles at t = 0 number tracked = 150, escaped = 0, aborted = 10, trapped = 0, evaporated = 0, incomplete = 0, coalesced = 0, shed = 0 I konow a half of the particles couldn't be located.I had changed the coordinate of the injection and this problem wasn't changed yet. Does anyone have any suggestions? Thanks in advance
