Output force as a function of time
 

I've been trying to export force on a body as a function of time from CFX-10 with little success. I can get the data I want as a txt file if I export from a chart (using expression eg. forze_z@body wall vs. time), but...I want to fully automate this to fit in with the rest of my automisation scheme i.e. not need to open post.

Help Appreciated

Re: Output force as a function of time
 

Hi,

You can do this using a simple perl script which has to loop over different transient result files. contact your local support office and you should get one easily.

I posted this a while back.

To take the forces from each of the transient output files use something like the script written below.

You need a session file and a DOS batch file.

--------------------------------------------------

# Session file started: 2004/10/21 10:38:42 # CFX-5.7 build 2004.04.01-23.00

! open (DATAFILE,">>Datafile.txt") or die "File Error\n";

! $filePath = getValue("DATA READER","Current Results File");

! $torque_x = torque("Rotor","X");

! $torque_y = torque("Rotor","Y");

! $torque_z = torque("Rotor","Z");

! $force_x = force("Rotor","X");

! $force_y = force("Rotor","Y");

! $force_z = force("Rotor","Z");

! $Cp_chord_wise = $torque_z/$force_y;

! $Cp_span_wise = $torque_x/$force_y;

! format DATAFILE= ! @>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> >>>>>>>>>>>>>>>> @>>>>>>>>>>>>> @>> @>>>>>>>>>>>>> @>> @>>>>>>>>>>>>> @>> @>>>>>>>>>>>>> @>> @>>>>>>>>>>>>> @>> @>>>>>>>>>>>>> @>> @>>>>>>>>>>>>> @>> @>>>>>>>>>>>>> ! "Full Path and Run Number", "Force-X (N)", "", "Force-Y (N)", "", "Force-Z (N)", "", "Torque-X (N*M)", "", "Torque-Y (N*M)", "", "Torque-Z (N*M)", "", "Cp-Chord (M)", "", "Cp-Span (M)" ! @>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> >>>>>>>>>>>>>>>> @.############ @>> @.############ @>> @.############ @>> @.############ @>> @.############ @>> @.############ @>> @.############ @>> @.############ ! $filePath, $force_x, "", $force_y, "", $force_z, "", $torque_x, "", $torque_y, "", $torque_z, "", $Cp_chord_wise, "", $Cp_span_wise !.

! write DATAFILE;

! close DATAFILE;

>quit

# Session file stopped: 2004/10/21 10:40:42

--------------------------------------------------

DOS Batch File

--------------------------------------------------

@ECHO Off

C:\CFX\CFX-5.7\bin\cfx5post -batch T:\ANSYS_CFX\Post_session.cse T:\ANSYS_CFX\1\1_001.res

C:\CFX\CFX-5.7\bin\cfx5post -batch T:\ANSYS_CFX\Post_session.cse T:\ANSYS_CFX\2\2_001.res

--------------------------------------------------

You could gave done some kind of perl loop, but i figured this was quicker to do.

If you can do it interactively, then you can do in the batch mode as well. All you need to do is make a session file out of your interactive session: 1. start Post 2. start recording a session (Session > New Session, then Session > Start Recording) 3. load file, make your chart, export data, etc. 4. quit You can now tweak the recorded session if needed and play it back in batch mode.

I have been fiddling with things in CFD-post. I know just enough about session file to automate the routine tasks I perform.
However, I am now thinking of adding some fool-proofing options via GUI to my .cse file so that a colleague can interact with it through a message box.

Here is my question: How can I use a Perl command to display a simple message box as part of my .cse file execution?

P.S Don't wish to be ignorant.. but, I have been struggling to get to a good staring point on using GUI thru perl. I am completely new to scripting... but, with some help-in-context baby steps.. I know I will be up and running fast... Thanks.
