Hi, I'm trying model our mine in terms of DPM level. When i entered DPM properties of engine from presets it isnt matching our real DPM levels. On the other hand if i change the DPM rates it is getting completely approximation. What should i do about that? Another question that how can i apply DPF to my DPM scenerio for understand what kinds of actions we need to take in the future?
