Particle-Source-In-cell (PSI-C) in DPM
 
Hi All,

Does any body knows how to get concentration of particles at required locations using DPM injection?

I am using Lagrangian particle tracking method. Any clues?

Thanks
John

Do you mean to view the results of the concentration of the particle phase in Fluent? Or do you want to access the variable that contains the particle concentration in a macro? The variable for particle concentration will be described in the dpm.h header file and is called something like SV_DPMS_CONC... Good luck.

Hi Walsh,

Thanks for your reply. I mean i want to monitor the DPM concentration at diferent locations in the domain. DO you have any idea can i do this using UDF?

Thanks
John

Hi Guys,

I am still stuck at this problem. Does anybody used PSI-C method UDF for DPM particle tracking. PSI-C method converts no. of particles in cell to the concentration of particles in the cell. Hnece, we can view/get particle concentration in the domain as like scalar in the domain.

Thanks in advance

hi, have you solved the problem? I have the same problem, can we add the dpm concentration to the variable list? and how to use the PSI-C method? thanks!

I checked the manual and find if we select "interation with continuous phase", the dpm concentration with appear in the variable list. but how we add this to the list when we do one way coupling without selecting "interation with continuous phase"?

I also want to display the contour of particle concentration.
how I can do this ?

I have managed to display the concentration contour in kg/m^3 after activating "interaction with continuous phase" , i want it to be in cfu/m^3, how can i do it?

Thanks in advance

Hi
as i understood, you have to solve it intransient. In DPM set you can mark the intransient solve . then you can track a particle.

Best Regards

@gan6030:
Could you please share your approach to explore contour plot of concentration ?
do you find any solution for CFU?
thanks

hi all
anyone succeeded to use PSI-C for concentration calculation in one-way coupling?
