Hi everybody,
I am new with learning COMSOL. I have a duct flow with an obstacle. I would like to obtain pressure plot in a specific point. But if I select the point where I would like to get the pressure information by time the pressure just drops to 0 and stays there. But if I check the countour plot of pressure I can see that the pressure is changing so it should not be 0 in my plot.
Thank you.
Best, Miha

Hi Miha,
Maybe at the beginning there is a high pressure value than it drops to a much lower one, close to zero. You can change the range of data to be plotted. In the Results node under the plot group you can change the axis limits. It may help your case.
Best regards,
