UDF macro to read the name of the case file
 

I would like to open a file and save data in it every timestep with a UDF. I would use simply:

char filename[]="outlet.out";
fopen("filename","mode")

For the filename, I would like to use the same expression as for the case file. Let's say my case file is CASE01.cas, and I would like to name my outlet file as CASE01_outlet.out.

My question is, how can I do it with an UDF? Does exist a macro which would read the name of the case file, and store it as a parameter?

Thank you for your help.

I am looking for the same, did you find any answer?
Thanks

You can do this using a journal files. Have a look at this link http://www.cfd-online.com/Wiki/Fluen...ournal_file.3F. There is also an example somewhere on the same webpage.
