To calculate the total mass flow rate of the escaped particles in ANSYS Fluent using the Discrete Phase Model (DPM), you can follow these steps:

Step 1: Enable Reporting

Step 2: Generate and Analyze the DPM File

If you have already generated a DPM file using the Sample function:

Step 3: Post-Processing

To compute the total escaped mass flow rate:

If the DPM file does not directly provide the total mass flow rate, you can calculate it by:

Total Mass Flow Rate=Total Mass of Escaped Particles / Total Time of Particle Simulation

Step 4: Use Fluent’s Built-in Reporting

Instead of manually analyzing the DPM file, you can:

Tips for Automation

• Use Fluent's journal files or macros to automate the process if you need to run multiple cases.
• If necessary, export the data to an external tool like Excel, MATLAB, or Python for further processing.

You can check in Reports > Surface Integral or Volume integral> mass flow rate.
