What is the proper way to use the divergence field inside the Pyro COPS workflow?
If I try to plug anything on the divergence output nothing happens.

Any tips?

I am trying this, divergence does not affect anything.

It does work, maybe bump up the values a bit to see

your setup applies divergence only in source area, but you can also test on different setups, like a simple setup where you feed the simulated temperature (scaled as needed) to divergence to get it expanding in hot areas etc...

You are absolutely right! The thing is that I was expecting that it would work exactly like pyro SOP which I use all the time but in this case I forgot to increase the divergence value a bit.

Thanks for the help.
