The interface is very easy to follow and understand, even for a beginner in 3d modelling. I have been able to create realistic models of industrial processes with ease. Sometimes it takes several hours for the simulation to run if you have a large domain, but this isn't so bad since most people will not be simulating so much. I would recommend azore to anyone interested in using it, as long as they understand what they're doing. The price might deter some users from trying out azore because of its high cost.
However, i think that the benefits far outweigh the costs. To simulate wind tunnels, heat exchangers, etc., azore is one of the best tools available.
