I have a controlDict file that looks like the one below, created in notepad and the extension is removed for foam. What would the problem be? The error given is "problem while reading header for object controlDict".

Hi,

The first lines should be commented out, but your slash is reversed there.

This "/*" starts a comment and this "*/" ends it. You have \*. Just correct it and I think it should work.

Edit:

This should work

Thank you, it has now got past the controlDict file but gets stuck in the blockMeshDict file now. I can't for the life of me see what the problem with the file is. When I compare it to the tutorial files it looks identical to me (aside from the different boundaries actually defined. Can you see anything wrong with this below?

Apologies please ignore this, I somehow had two blockMeshDict files in the case folder and it was reading the wrong one.
