Saltation and Particle Charge Polarity

1

Particle Renderer — 3.9.3 documentation
Does the LPT also keep track of charge polarity of dust particles?
Or of graupel particle charge polarity?
And of the effects of static electric fields?

Hi, the particle renderer can show any variables that are defined in your Data Collection Particles (DCP) dataset. If you add scalar variables for charge polarity similar to what’s shown for the speed variable in the documentation link you’ve posted, VAPOR will be able to render them. Note that we are not simulating these effects in VAPOR. We are just showing what is represented in the data itself.

I would like to see a feature like that which considers the effects of E-fields on particle flow.

Aggregate fragmentation of saltation, the charge generation existing in the suspension, interaction with the LPCR of the tripole charge structure of thunderstorms.

Right. In the example docs, we have a scalar field for “speed” that gets assigned to each particle. The scalar variables like aggregate fragmentation of saltation would need to be added to your file in the same way. Does that make sense?

 netcdf particles_000 {
 dimensions:
         P = 200 ;
         T = UNLIMITED ; // (1 currently)
         axis = 3 ;
 variables:
         double T(T) ;
                 T:units = "seconds" ;
         float Position(T, P, axis) ;
         float vel(T, P, axis) ;
         float speed(T, P) ;
 }

Yes. I will have to work with this to see what kind of output it can generate.
