how to convert .txt files to OpenFOAM format

boffin5 · July 25, 2021, 14:48

Hi,
Recently I found a site showing some simulation case files for 0, constant and system, so I copied them as text (.txt) files. Now, I need to convert them to OpenFOAM format files. I thought the method would be easy to find, but after much searching, all I can find is some cryptic info, along with the comment, "just go write a program". But I'm not a programmer, and would appreciate some examples of how to do this.

btw, Thanks to all who have been an indispensable help to me, as I jump from problem to problem.

OF accepts plain ASCII.

Hey Alan,

you don´t need any special file type for OF, so just name f.e. your velocity file "U" instead of "U.txt" and it works.

Danke Schön and Thanks!
I appreciate your help, but I just used brute force and re-typed the files; thankfully they weren't too big. So I could have just renamed them to remove the .txt? What does f.e. mean?

>just renamed them to remove the .txt?

Yes, that's it.
