How to calculate the concentration of DPM (Urgent)
 
Hi guys,

Can check how to get the concentration of DPM, i got zero result at all time when i on the x-y plot. i am using water vapor as the material.

Plz help me.

thanks and regards, alex

Is-it the same thing when you plot the dpm concentration in the contour menu?

Hi Urg,

Thanks for replying me. In the contour plot, pathline and xy plot i face the same problem. its show zero concentration. i am able to get the pressure, velocity and etc, just except the concentration of the DPM. Furthermore, i can show the simulation flow in the pathline when i switch on the pulse.

The concentration result is very important for my research.

Thanks and regards,

alex

Hi Alex

Have you coupled the DPM with the continuous phase calculation? If not, then this may be your problem, try switching this option on and re-run your calculation.

If you have nothing in concentration, it means that you have a problem with the set-up of dpm calculation.

But I haven't enough information to help you

Hi Mark,

Thanks for replying to me. Where can I switch on the continuous phase calculation? at the pathline?

Thanks and regards, alex

Hi HVN,

Thanks for help. I try look into this problem again. But i am actually following a journal with its step. I dun tink the step is wrong, maybe is my concept in keying data. Btw, do you have any reference regarding DPM or something related? i have read through the FLUENT Manual already. It still dun help me.

Thanks and regards alex
