create chart average area pressure vs time

Nuclearbomb · February 2, 2021, 22:29

Hello. I want to plot the "area average pressure at inlet" vs "time" in CFX-post.
There are some posts about the chart.
However, anything did not work for me.
Is there any way to plot the "area average pressure at inlet" vs "time" ?

It is easier to do this during the calculation itself.
To di this, goto Pre, just define an expression like areaAve(Pressure)@Inlet in OutputControl>MonitorPoints>Expression. Then during the solving process, you can create a plot versus time. There, you can also export this for use in Excel or whatsoever.

You are able to make a chart in cfx post by:

Insert -> Chart -> XY transient or sequence

This makes the X-axis time and you can put your expression in for Y.
For large data files, large meshes, and lots of timesteps, this can take quite some time to calculate actually.
