I did a simulation on Ansys Fluent for unsteady case, and I want to get the static pressure time series in a location (point, probe) using CFD-post, is it possible? and how ?
Change the AUTO SAVE settings in fluent, so that after required time intervals your case and data will be saved at particular destination folder. After finishing your total simulation, start post processing your data, at different time intervals for the the distribution of pressure at that particular point.
Yes it is possible to have a time series just change the Auto save settings (which is by-default set) just set your precriped interval and run your simulation and save that folder....repeat above steps...remember to save all folder with a particular directory ..
Hi, You can also do this task in the so-called "Results" module of the WorkBench project. For instance, at the end of the simulation you can open the Results module and create a "Chart" inside the Report section of the Outline box: Click on Insert, then select Chart. In "General" select the type of chart you want to create (in your case select "XY - Transient or Sequence"). In "Data Series" select the "Data Source" which is the location where You want to plot the time series (so first you have to create the location, such as point, line, surface,,,,). Select Custom Data Selection, where you can specify the data you want to plot on Y-axis (pressure, Total Pressure, Velocity,... or other Variables you can create by means of multiple expression in CEL section). You are almost done....click on Apply and after some minutes or hours or days (it depends on how much huge is your time serie) you will visualise on the Chart Viewer your desired plot. If You want you can export your time series on a comma separated values file (*.CSV).
I hope this was helpful.

...Also You can use export directly your results using the export option in file.
file --> export --> select desired domain --> select desired variable --> export.
The file will be in CSV format: you can format the file in "formatting" schedule where you can select the separator or precision.

Click on domain and select the section and Export
For plotting click on properties and modify as per the req
first determine your point, surface, ... in FLUENT to print time series (surface-point) then go to "Solve-monitor-surface", add "Surface monitor" and define what to write in notepad. for example if you want to write time series of velocity, select "vertex average in Report type", "Report of velocity" for the pressure time series choose the "Integral in Report type" and go ahead
Hi
Comments above for setting autosave for having solutions at all time steps are true.
After calculation is complete, go to cfd post, create a point at desired location and then create a chart. At general tab, set the type to XY-transient, under data series set location to the previously specified point. Then, for example, set the X axis to Time and Y to another variable.
Click apply.
There you go, chart is ready
True the chart will be ready in Ansys post, but how to plot them for a specific time range? for a specific time interval? Help please,
Basil Jamal, when the plot is ready for the whole time range, you can export .csv file (the export button is at the bottom of "details of chart panel") and then choose desired time range for plotting with your spreadsheet software.
also, from CFD post, go to details of chart panel (assuming you already followed steps from my previous comment and plotted the chart), then go to X Axis tab and uncheck "Determine ranges automatically", there, you may determine the limits of your desired time range.
Location ---> define you node (by number or by location) = point1
Insert ----> chart ---> general (XY-transient or sequence) , data series (location = point 1), define you Y and X ----> apply to get the curve in time domain.
after that you can export your data by selecting export in chart window.
Hi every body.
I want study the unsteady model in traditional kiln. I have simulated the model on steady but I will simulate on transient. When I do the I feel the temperature is not varied.
I will plot:
--the temperature as fonction time inside the kiln
--The temperature as fonction time between (the flow and the brick)
Hi Soorena Gharibian
Thanks for the info. Is there any way to plot the time series of data on a plane rather than a point. I mean, like plotting the evolution of average velocity on a plane with respect to time.
I tried the same strategy as mentioned for point data, but when specifying location, the plane that I defined is not shown. I guess only points are available in this method.
I am thankful if anyone can shed some light on this.
Regards
