Memory Stack Function

Andy

I have done a transient run with up to 24,000 timesteps to calculate pressure fluctuations on an aeroacoustic noise source. To complete the run, I had to reduce the number of coeff loops to 2 and set a memory integer stack to 3.5. Now what had happened is that toward the tail end of my run, the pressure fluctuatons get smaller and smaller until it looks like the whole thing has settled down to a smooth line. This should not be the case and i'm wondering if the stack function averages out the results causing me not to read further pressure differences. Please let me know if anyone out there knows if this is a side effect of the stack function. It shouldnt be the coeff loops as the cod is still converging to 10e-5.
