Data save interval for EDEM in EDEM-Fluent coupling

Bharath Rangavittal

Hello,

Is there a way to set up the data save interval for EDEM data in EDEM-Fluent coupling?

Hello Bharath,

You can set the save interval in EDEM->simulator panel->Target save interval.

Best regards

Hello Zilong Qui,

Thanks for your reply. 

Yes, that is how I usually set the save interval in simulator panel when I am using EDEM alone.

But, for some reason, the same does not work after EDEM-Fluent coupling. 

I am wondering if there is any other way to set the EDEM data save interval in EDEM-Fluent coupling. 

Thank you!

Hi,

The EDEM-Fluent coupling essentially works as lots of small simulations, the length of a Fluent timestep. This means you will always get an EDEM save every data exchange with Fluent. The data save interval should still work, but only if it is less than the Fluent timestep.

I haven't tested this, but from memory you should see the following:

Using a Fluent timestep of 0.1 and an EDEM timestep of 0.01 = EDEM data every 0.01 s
Using a Fluent timestep of 0.1 and an EDEM timestep of 1 = EDEM data every 0.1 s
Using a Fluent timestep of 0.01 and an EDEM timestep of 0.1 = EDEM data every 0.01 s

Long story short, the data save should be the minimum of the Fluent timestep and the EDEM data save interval.

Cheers,
