I have tested my model with the gas charge accumulator and it really showed results that were very wierd. For example, according to the model equation, if the pressure at the accumulator inlet becomes lower than the precharge pressure then the fluid volume should become zero, but im my tests, the model was showing a pressure value far greater than the precharge pressure by setting up zero initial volume. Few more fundamental tests like this, including my previous thread regarding the initial value mismatch confirmed that there is something very wrong with the Gas-charged accumulator block. On the contrary, I have run all the tests again by replacing the gas-charged accumulator with the spring loaded accumulator, and voila, the spring-loaded accumulator is working as expected according to the equations. It has passed all the serenity tests very well.
It seems that the gas-charge accumulator block is a culprit. Please comment on this as I am very anxious for the response.
