Dear all,

I am simulating swirl methane flame by employing ANSYS Fluent. Complete simulation with 3D mesh consuming much time, thus, is it possible to get the final solution by feeding a velocity profile corresponding to non reacting flow (cold flow) obtained at burner exit using 3D mesh as a inlet BC to inlet of outer domain which is of 2D mesh?

In short: 3D mesh is used to obtain velocity profile at the burner exit. Can we feed this velocity profile to 2D mesh based outer domain (combustor) as a inlet BC to get the final solution?
