i wish to simulate a particle tracing in a fracture.
i can do this programmaticly with fortran.
i want a lognormal distribution of particle diameter. so when i start the simulation at time=0 a distribution of particles is released. how may i do this?
thank you.

Hi
I think you can directly incorporate it on your inlet node of the particle tracing physics.
If you choose density in your “initial position” of your inlet settings you can choose the number of particles and density. You can write the function you want to use in the density box “density proportional to: ”
Alternatively you can also define your function under: component (1)>definitions>functions
Then you can use that function to define your distribution in the same manner as above (put it in “density proportional to: ”)
Hope that helps
