monitor pressure
 

I have a question concerned about pressure monitoring in transient analysis. I want to monitor the pressure at a point that i have create in Point Surface.

After that i go to Solve>Monitors>Surface>check plot,print,write when time step>Define (select the created point, report Pressure at Static, report type integral)>ok

when i iterate the model, my monitor's window just show the straight line at 0 Pascal in each time step.

What should i do to get the correct pressure graph?

Re: monitor pressure
 

A point has zero surface area so selecting integral for a point will always give you zero.

Try using average for the report type at the point.

Thank you CDE.

I have change it to vertex average for report type,it's really work but i found the pressure graph show in monitor's window higher than total pressure that i set in inlet boundary conditions.

How to solve this problem?

Re: monitor pressure
 

What inlet and outlet boundary conditions are you using?

Are you monitoring static pressure or total pressure?

Reply CDE,

i use Pressure_inlet and pressure_outlet as my inlet and outlet.

i monitor static pressure.

what is your opinion about this setting?

I did a temperature monitoring point, but when i openned the file of this monitoring, i found only this message:

"Convergence history of Total Temperature on point-5 (in SI units)" "Iteration" "Facet Average Total Temperature"

One question: where are the results of the temperature field in my transient simulation.

The files are in:

Thanks!
