I have some problems in a THM process simulation. I use a 2D model to simulate the injection process in EGS. However, I found from the first result vtu file that the pressure distribution contains a large area of large minus values like the second picture. In fact, I set the distribution of pressure as an approximate hydrostatic condition initially, like the first picture. I attach my prj file here. Can anyone tell me what’s the reason for my abnormal inversion pressure result?
