I'm using file injection for DPM particle injection. When calculating, every time step the error will appear, but it seems no problem on other place, that is, the calculation is converged, and the number of particle parcel is correct as my injection file. So I wonder why this error appear?

Are you getting the whole particles listed in your injection file really injected? Can you paste the first lines of your injection file here and aslo make a particle summary report and add screenshot of it here?

I’ m sorry I can't upload picture through the computer although I tried some times,maybe something wrong with the computer or website. But I can paste the first lines of injection file.The first two lines are head of the file.Then the data of the injecting particles. I set 50 lines data, which means it will inject 50 particle parcels every time step according to the file. And the fluent console will appear "Injecting 500 particle parcels with mass ... at t = ..." (I set 10 injection files and every file has 50 lines data)

The .inj file shows as below:

Can you check the formatting of injection-1? Can you please assign a regular name for the file injection instead of using 1, 2 ...50 use please a name like "myinjection-i:j" i with i an index referring to the injection file (say from 0 to 9) and j the parcel id which needs to be injected.
