the way of set psd

Asked by fengjingyu on 2018-12-11

Hi everyone,

I would like to know that ,In addition to generating particle distribution according to psdSizes, psdCumm, rMean and rRelFuzz, there are other ways to generate particles of different sizes.For example,particles are generated in proportion to a log curve.

thanks in advance.

Hello,
cannot psdSizes and psdCumm be used to approximate the desired distribution?

Hi Jan:

I'm wondering if I can generate particles that satisfy the equation that I set up, like a normal distribution

Regards,
Feng

Hi,

I would advice to just discretize your continuous equation (describing eg a normal distribution curve with a finite number of points), and go to Jan's suggestion #1.

Psd determined in the lab can not be continuous either ;-)

Hi,
Boost has plenty PDF models that you can use in replacement of the current one if you are ready to read the c++ code and modify it to achieve your goals.
Needs some background in mathematics and in c++, obviously.
