Hello,
You clearly start to use TELEMAC-2D.
In that case, I can give you advice to follow before I can answer to other questions:
- read the TELEMAC-2D user manual available here:
wiki.opentelemac.org/doku.php?id=documentation_v8p4r0
- as recommended in the rules of this forum, in particular the first one:
"Check that your question has not been answered anywhere else on the site. Use the search feature."
Your question has already answered many times with the tricks to avoid in particular with Windows (path, where to run the example...). We cannot always answer the same things to classical questions of beginners.
