Initialization of dynamic model

[DAH7542]

I forgot to mention the "dynamic initialization" which is used whenever tilted fluid contacts are present in the reservoir due to hydrodynamics. Some approaches to do this include 1) using pseudo injectors and pseudo producers in the updip and downdip structural positions and 2) using analytical aquifers and set a pressure gradient across the grid. Several years (or decades) are then simulated to reach a dynamically stable condition.
