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

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 pnrps@hotmail.com
