Hello,



i have some problems to automate Ansys. I am completly new to Ansys by the way.

My task is to simulate a large number of centrifugal compressors. For that i have a Matlab tool, that generates me the needed .inf files for Turbogrid. Afer that i want CFX to calculate the efficiency.


Now i need to automate Ansys to make the same steps for all the generated .inf files. The best way i found so far, is to create a session file in the Workbench and record my steps. Is there a better way than this?

And is it possible to control this from Python?



Any help is appreciated.

Make sure you are talking about the correct software names.

ANSYS Workbench = Tool used to control all ANSYS products (from FEA to CFD, electro magnetics and everything else)

CFX Pre = pre processor for CFX.

CFX Pre can use session files, workbench cannot. Are you actually using CFX-Pre?

Thank you for answering.



I got that term wrong, i recorded a journal in the workbench, where i set up a trubogrid and a cfx instance. That works atleast if i use the same .inf file again, didnt testet what happens when i open another .inf file with the same journal.



As far as i know i can adjust the journal file in text editor after recording it. Is there a list of commands i can use, for example to change a setting in CFX-Pre without recording the whole journal again? Couldnt find anything like that in the Ansys help documents.



My method now would be, that, after the first iteration, i open this journal file with python and change the path to my next .inf file in it and start the journal again.

I just dont know if that is the easiest way, or if i just dont know about a feature that would help me.

I use workbench as little as possible. I use the CFX tools stand alone almost always as you have much more control over what is going on, and it crashes less.

If you are using turbogrid, CFX-Pre and the CFX-Solver then I would automate that myself using a batch file (if you are windows) or the equivalent in LINUX. All these tools can be called from the command line, and controlled using session files, CCL and other methods.
