Hi everyone,

I m new user in CFD and i am trying to simulate flow through the cylinder in tutorial (Programmer's guide - contents 3.1) using Openfoam 2.1.1 . But some errors has occurred that I can not be fixed .
I can't use the command blockMesh in this tutorial!
Can you help me ???

Here is the error details

As you are trying to use codeStream, change allowSystemOperation to yes as suggested in error message

Thanks ybapat,
I had corrected it. The "controlDict file" have been hidden so just press Ctrl + h to show it up
