Error running a flow past square cylinder
 

Hi :)
Please look at the snapshot attache with this past .
And guide me where i am doing mistake

Error due to probe usage in controlDict
 

I have run the case without forces and force co-efficients in controlDict. It worked all fine I modifies to get Cd and Cl as follows
