Hi all,

I am trying to implement porousSimpleFoam in my case and there is an error which I do not understand and I could not find much about it either.

Here is the error:

Can anyone explain to this what this io error means and how to resolve this?

Thanks in advance!

Okay I finally found out it was due to the missing semi colon....
Problem solved :-)
