Hi,

Combustion modelling is not a good place to learn CFD. It is tricky at the best of times. Have you done examples and/or training on simpler single phase, non-reacting models? You have to be very comfortable modelling single phase models before adding combustion.

Hi,

Do the tutorial examples provided with CFX, do CFX training courses, do a CFD course at uni.
