I have this simple set up that I use every time when simulating Godzilla shooting his atomic breath, and the set up is basically like this. I have a cylinder that's a flow object, the domain, and a wind force field facing the direction of the breath being shot with a strength of 50. Sometimes I notice when I have a set up like this the fire curves too much, what I mean by this is that the flow of it bounces up and down crazily, like a sea or a flag. Is there a way to turn this down in the settings of the domain or flow object or even the forcefield? Thanks!

Here's a link to the settings for the force field, cylinder, and smoke domain. But you can see it curves a lot which I'm trying to make it not do.

Adjust the Vorticity settings to affect the turbulance in the smoke or flame. From the Blender Manual pages :

Vorticity Controls the amount of turbulence in the smoke. Higher values will make lots of small swirls, while lower values make smoother shapes.

Reduce Vorticity for a more stable flame.
