hello,

I'm working on a flow in which I inject water droplets. I use the DPM model with an unsteady flow. the calculation is correct. the problem that I'm facing is the particles history. I wish to now how I can to save particle trajectories.

thank you for your anwers

can you help me to share a calculation of for example one parameter about particle history? my suggestion to particle history is try to displayed at pathlines of DPM panel as a particle trajectory by single particle stream or particle track: for example from one location to other location in the system geometry?

Hi

I'm also working on a flow in which I inject water droplets. I use the DPM model with an unsteady flow. The main problem that I'm facing now is the particles coordinates. I wish to now how I can to save trapped particle coordinates.

thanks in advance for your help.

Hi,
after initializing your case, go to Reports.....Discrete Phase...Sample and choose all the walls of your geometry in the left menu, and in the right menu select your injections, then click start (note that all this process should happen after initializing the case not before it) and start the calculation, when the calculation is completed go to the previous menu (sample) and just click stop, you will see some files with dpm suffix (wall.dpm) are saved in the folder that your case is saved, open them and you can see all the particles datas that are traped including time, coordinate and ...
