What is the upsurge ratio in the transient calculation summary?


The upsurge ratio is the maximum transient pressure divided by the initial conditions pressure. 1.0 would mean that the maximum pressure is the same as steady state. The higher the number the higher the upsurge, relative to the steady state pressure. It's basically a reference value to see where the highest surges are occurring, which will help you with transient modeling.
