Hi all! I'm a bit new to OpenFOAM, but have attempted to solve this particular issue on my own. I can't seem to understand why simpleFoam won't run...

Hi Keegan,

welcome to the forum!

You will need to provide more information about your case if you want to get a help. Eventually you can read: Guide: How to ask a question on the forums

Kind regards,
Robin

Hi Keegan,

What you mean the solver doesn't run? Is there any error?
