Issues encountered when extending ThreePhaseBlackOilModelDP to ThreePhaseBlackOilModelDPDP

[tianyong liu]

I attempted to extend the ThreePhaseBlackOilModelDP to create the ThreePhaseBlackOilModelDPDP. This includes the classes I constructed, the equations, and the main code. I also defined the Kazemi flow for three-phase fracture-matrix interactions. In my preliminary model, solution gas and volatile oil are not considered. The current issue is that although the code runs without errors, the oil well does not exhibit a production decline. Regardless of how long I set the production period, the formation pressure remains almost unchanged. I would greatly appreciate it if experts could help review my code. Any assistance in resolving this issue would be highly valued.
