When I hit the vorticity command in terminal the error comes up: Time = 1500 Reading U Calculating vorticity --> FOAM Warning : --> FOAM FATAL IO ERROR: keyword curl(U) is undefined in dictionary "/home/ali/run/2/system/fvSchemes::gradSchemes" 1. Is there any body explain me what the curl(U) is? 2. Is there any suggestion for the most suitable gradSchemes for curl(U) in fvSchemes? I really appreciate for any help.
