Concentration of Lagrangian Particles

cwl · May 27, 2022, 12:23

Hi everyone!

I can't find a way to get or to calculate a simple thing .. just a concentraion (particles/m³) of Lagrangian particles of specific size range (non-constant size ditribution) in a transient simulation.

PS It is a really common thing - so I'm pretty sure it is there, it's just I can't see it.

Can you please try one thing. Create isosurface with particle diameter. And create element count report with isosurface as a part. I don't know how but its working for me. I know it may not be right but I cross-checked with counting few hundreds of particles.

Thank you for idea - but isosurface does not look like a correct way since particle diameter can be any value withing the injector's range. A threshold could be an option this way.

But anyway - I can't see how that approach could give not the average concentration, but its distribution in space.
