Hello. This is my first post here (after some time lurking) so please be gentle.

I've recently picked up OF and am a novice to the tool.

My case is dispersion of CH4 in an open environment exposed to wind. The domain is just an open box. So far I've set up a case with an inlet for wind from one of the sides, and a small inlet for gas at the floor. The scenario could be an offshore pipeline rupture from which gas(CH4 in my case) has leaked to the surface of the sea, and my task is to look at the dispersion of CH4 in air.

So far the wind is working well, and I did configure the 'gas inlet' to a standard air inlet, just for starters. And up till now I've been using simpleFoam, taking pieces from motorBike and turbineSiting tutorials. Now here's my problem: I'm not able to implement the gas profile into my case. How to make the 'gas inlet' spew out gas instead of air? Any tutorial recommendations?

I've been through several tutorials(ie. counterFlowFlame2D) but it has become a bit too much for me to handle. As mentioned, I am quite the novice, at best.

Also, I recognize that I should throw simpleFoam, and instead use the likes of perhaps reactingFoam? Any help is greatly appreciated! Any help at all. If you want me to provide any info, I'll be happy to.


Cheers,
Lasse
