DPM diameter mass distribution
Is would like to use the RosinRammler distribution for a solid cone injection point. I try to check the sizemass distribution from a DPM sample on a plane in the geometry (from the .dpm file that is created). I do this with the diametermass flow information in this file. However, I do not find the distribution specified. Instead I get a uniform distribution of mass. Does anybody have suggestions?

Perhaps this thread can shed some light?

Re: DPM diameter mass distribution
Thanks HS for pointing me out. This is interesting information, but it appears that this person finally found that the mass distribution did correspond to the RR distribution (he found the problem for the number distribution). I find the effect both in the number and the mass distribution: both are uniform.

Check out the mass flow represented by each diameter.

Re: DPM diameter mass distribution
That's what I did  create a .dpm file with diameter and mass flow for each particle. Next, create bins with diameter ranges and calculate the summed mass flow for each bin. This gives me a uniform distribution.
