Hi

I want to define a source point in CFX to model combustion in a back ward facing step, actualy i want to define a source point for reaction progress and the unit is Kg/s, i have really no idea about this, because the reaction progress 0 shows no acombustion and 1 points to a burnt mixture, so what is this source point in Kg/s????

I would appreciate if some one could help me in this matter

What do you intend to model? Ignition as a transient process?

No steady state

First i assume two regions in the chamber one consists of step with higher temperature and the other part with lower, but interface between to parts seemed behaves like a wall. so i want to use source point instead of a part with higher temperature.
