Error From MRFSimpleFoam (wiki)
 
Hi Foamer
i'm new gay to use openfoam and i interesting in wind turbine and i download case form wiki and now i try to run case some problem i can solve and pass but for Last problem
i don't understand where is problem?? Let's me know what's problem ??? or How to Pass this error ??
Thanks you so much.



error when programs run to time = 17 like this
