Hello & good day,

I intend to model a scenario where atmospheric wind enters the fluid domain on one side and leaves the other. Once the steady wind field is generated, I will let methane gas to get inside the fluid domain from a circular surface from bottom plane of fluid domain. ( diagram attached with the query for illustration)

I want to visualise the methane plume dispersion under the wind influence and also to see the flammable cloud concentration of methane.

It is to state that I am a beginner user of this module and I searched for the solution in this forum and also few video demonstrations but I cannot find exact resemblance and therefore modelling guidance.

I would appreciate If I am guided on:

1. The complete scheme in fluent to model this scenario
2. Appropriate models and boundary conditions

It would be generous of you and helpful to me if relevant guidance supported by examples if not exact but nearest to this scenario is shared.
