DPM monitor problem
 

dear friends,
I am going to model sedimentation in a tank which water and solid like sand flow through it, I've done the water flow calculation, and also I know how to model solids as DPM. my question is that how can I monitor that how much of solid goes out of the tank?how can I monitor the out let?
thanks

Hi Danial,
You can use "Sample" feature via : Report -> Discrete Phase -> Sample ...

Choose the surfaces you're trying to monitor, "Start" sampling, run the simulation, and "Stop" sampling at the end.

thanks, dear Sina, I want to see how much solids will remain in outlet flow. Is it possible? how can I do it?

Choose "Outlet" as sampling surface, and after stopping the sampling, you will have .dpm file for outlet. That's an ASCII file, so you can open it using a text editor (and even Excel), and simply sum up the mass of the collected parcels at that surface.

thanks a lot,
I am facing a problem ,I follow ur instructor and as I start this Error comes ('Warning: unable to append to file out.dpm, opening new file.'), whats the problem? what should I do?:confused:

You have probably enabled the "Append file" option. When you have it ON, it will search for any existing sampling file to append the new samples to those files. When you don't have any sample files, that warning pops up, and it is not a big deal. If there is no existing file, it will create one.

I'm also having the same issue, how did you solve it?

I get this warning:
"Warning: unable to append to file out.dpm, opening new file."

Then it proceeds to create several files for the same plane. I either have to find a way to merge separate files into one single file or find a workaround for this.
