Extracting results file to a text file

ealatawi · December 15, 2009, 02:36

I did simulation using CFX and I want to extract the CFX results file to a readable text file. Is there any comments or suggestion please.

Thanks

Try monitor points or exporting from CFD-Post. Both are covered in the tutorial examples and the documentation.

I like, as Glenn mentioned, creating a monitor point. Pretty easy to do. In CFX-Pre, go to the Output Control. There's a tab at the top labeled "Monitor". In here, there's an option to "Monitor Points and Expressions". Create a new one. The list of standard variables (e.g. absolute pressure) will appear. You can also input an expression (e.g. for drag force, the expression would be force_x@[name of object]). When the Solver is finished running, right click your monitor points and export to a .csv file (these are better than .txt because Excel imports the values in separate columns automatically).

Voila.

If you have several files, you can do it also in batchmode.
Therefore record a sessionfile in cfdpost and then create a .bat file containing:

<Path to bin>\cfdpost.exe -batch <path to sce>\_.sce <path to res>\_.res

bin --> binary folder of your ANSYS distribution
sce --> folder containing your sessionfile
res --> folder containing your resolutionfile

If you start this in cmd you can export data automatically or do any other operation in cfdpost
