Hi Guys,

I'm relatively new to CFD and I want to obtain mass concentration values for different species at my outlet over time for an oscillating flow. The flow completes it's oscillation every second and I have completed 1 cycle, but I would like to know the concentration values at the outlet for the different species for every time step until the 1 second has completed. Any idea how to achieve this?

Thanks

bu the way, this would be for certain cells at the outlet - is there a way to find concentration values for cells at the outlet for any time step?

Hi,

You will have to set up monitors at the outlets. If you're interested in monitoring species in a 'custom' region, you can set up a New Surface in the Surface Monitor panel. It's very user-friendly, just read the User's Guide and you will be fine: https://www.sharcnet.ca/Software/Flu...urfaces_define

thanks for the reply. I selected the monitors at the outlet for mass fractions of one of the fluids, but wasnt sure what to select such as integral etc for the report type?

Also, how do I view the data/results?

Thanks

Please read the guides. This is a basic question and the best, crystal clear answers are in the guides and the tutorials, not on the forum. Here's the calculation associated with each Report Type: https://www.sharcnet.ca/Software/Flu...e_surfint.html
