Help to plot variation of absolute pressure Vs time in transient problem
1 Attachment(s)
Hello,
I am analyzing a oscillatory flow in channel. I am using 2D,Pressure based solver, Transient model. I want output at a one point. I had defined a surface monitor at that particular point for Area weighted absolute pressure Vs flow time....I think it is right but my output is as shown in fig. Can anyone help me to correct this???????:confused: Thanks...... |
U are getting constant pressure (101325 Pa) but the graph looks strange. should be parallel to time axis ?

Other than that, it seems (at least your plot) is outputting correctly. If it was a transient simulation I would expect stronger pressure oscillations, but it seems your pressure is fairly constant with small oscillations (these are probably introduced by the averaging scheme). You are also plotting against time-step so it may be hard to judge. |
Thanks

I had also monitored with respect to flow time but the output is same. and you are right strong pressure oscillation is expected with amplitude approximately near to 7500 to 8500 Pascals with oscillation frequency of 614 Hz. |
