Parameter sweep from a txt file

Adam_22211

Hi everyone,

I am using parameter sweep in FEKO.

I would like to know that how I can import a text file for parameter sweep. My parameters are randomly varied, I can manually give my data to the FEKO parameter sweep tool, and run it. But, Is there any shortway for giving the data from a text file? 

thanks in advance

This is not possible directly by just reading a text file, but it would be nice extension for the script.

In a more indirect way I could suggest the following:

If you create a parameter sweep and cancel the running of the Feko solver you will find a folder "parameter_sweep" in your current folder.
There you will notice the script created a number cfx files, equal to the number of possibilities, e.g. if you specified 2 variables with 3 different values each, there would be 6 cfx files created in total. Note the naming convention of these.
These cfx files are created with cadfeko_batch from the command line where the variables are modified and the mesh created with e.g
cadfeko_batch <mycadfekofilename> -#feed_dist=10 -#height=0.2
Just search for cadfeko_batch in the Altair_Feko_User_Guide.pdf

You would need to create manually these cadfeko files with your own command line script and follow the same naming convention/sequencing as the script with these files.

Thereafter you would need to run each cfx file, also with a command line script.
This uses runfeko from the command line. In the Feko Utilities chapter in the Altair_Feko_User_Guide.pdf there you will find info on running Feko through the command line with runfeko. E.g. to run the first cadfeko file, you would use:

runfeko <mycadfekofilename>_01.cfx -np 4

where the -np 4 would specify 4 parallel processes if you want to use parallel solving.

After running each cfx file you can run the Postfeko part of the parameter sweep script.

Dear mel,

Thanks for your response.

The thing that I avoid is to create the cadfeko files manually. I understand now there is no direct way to read a text file.

Thanks for your valuable suggestions.
