Can someone help me to obtain time averaged solids volume fraction for the DPMFoam test case- Goldschmidt?
I ran it from 0-5sec as normal, but I need to do the time averaging from 5-10s. How can I do it? Should I add some fieldAverage in controlDict?
Please help!

You can use voidFraction object function by adding the lines below into your kinematicCloudProperties file. This creates solid fraction field in your timestep folders so that you can analyze/average them afterwards.

Code:
cloudFunctions
{
    voidFraction
    {
        type            voidFraction;
    }
}

Nice to meet you, Utkan Caliskan! I'm a green hand in CFD. Could you please teach me how to acquire “time-averaged value” of static pressure in detail?
