Hi everybody,

I am trying to plot the diameter distribution at the inlet which is injected from the inlet.

I tried to plot an histogram of the diameter distribution using Reports-Discrete Phase-Sample and then Histrogram, but it didn't work.

Can anyone help me?

Thanks,

Lucas

I have the same issue. Have you solved it in the meantime?
I would like to know exactly what has been injected.

did you sample and save the sample file of the dpm first?

Thanks, yes, but a sample at the inlet seems empty.
So the only way to know what has been injected is to add trapped, released... fractions on outlets and walls as far as I've found.

But what is injected numerically seems to be always one particle per diameter per node. The R-R distribution is probably used for weighting (e.g. impact on the fluid in case of two-way interaction). But I didn't find a way to easily visualize it in the histogram.
