edit: figured ut out
I am trying to create an oscillating flow case . for as a start, i tried to create a simple 2D case with two pressure outlets. one with an oscillating pressure of 20,000 pascals and the other with a constent pressure of 0 (gauge). For some reason the 0 pressure outlet refueses to stay at 0 pascals.
I am enclosing some screen shots of the first cycle- the first half is as i expected- the left part oscilates and the right is maintained at 0 pascals. however, in the second half of the cycle the pressure at the right outlet drops.
the case is attached as well, and the boundary condition defintion. happy to supply any required information
