Sharp Arrow Smoke for Explosion Using an Emmiter

[Gubkin]

Hello everyone,

I am trying to achieve an effect similar to the video bellow:

Explosion

I am currently working on the secondary arrowed smoke that rises right after the explosion.

My problem is that I cant seem to figure out how to make the beginning of the arrow sharp and also I want the smoke to expand significantly more after the initial arrow (check attached image)

I am currently doing this with an emitter, is that the right way to go or I should use another technique like creating velocity arrows and using the pump relationship?

Any other advice on creating this effect or on fluid simulations in general is welcomed.

Thanks a lot

You can try for example to add divergence.
