Saving bulk results on a plane as a function of time in transient analysis

cfd1980 · September 26, 2013, 15:40

Hi everyone,

I am running a transient analysis and am trying to get a delta P between two planes (one near inlet and one near outlet). Is there a way to automatically save the Pressure (or any other variable for that matter) automatically at every saved time step. I have seen the Bulk tool which will give you the average values over the plane at individual time steps but there is no way of automatically saving these values as a function of time. You have to save a *.csv file individually at each time step manually.

Also the Decision center seems to be for seeing the variation between the different scenarios not for variation with time in an individual scenario.

thanks in advance,

One trick to getting the data (assuming you have intermediate save results):

Set your plane where you want it.
Right-click and go to the animation pane
Animate the results through your save intervals
While animating go to the Bulk Calculator and select the quantities you want, you will be able to save the bulk results for that plane across all saved intervals into 1 csv file

Repeat for any other plane

Hi everyone,

I've got exactly the same problem. After searching the internet a little I found this cool forum and even a hint on the Autodesk website (at the bottom) giving the same advice this thread.

Nevertheless it doesn't work- and I'm starting to doubt myself.

Propably it's one of these stupid faults..

So I would be very grateful for any help!

I'm using Autodesk CFD 2016. I carry out the following steps:

Running a transient analysis
Placing a plane in the model
Open the animation pane
Clicking animate
After the "animate"-button turns grey, clicking the "play"-button in the animation pane
While the animation is played, right clicking on the plane placed in 2.
Clicking "Buld data"
Choosing the desired data (in my case mass flow)
Clicking "save" in the bulk data dialog

What I get is a CSV-file with only a single datapoint from the time step where i pressed "save". Instead of one CSV-file with all the data of all time steps.

I'm grateful for any help after I wasted so much time on it.

Ok, I found it out- the 2016 Version sucks!

With Autodesk CFD 2015 its working perfectly fine!
