Dear Foamers,
I am planing to use vorticity as a post processing utility. 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. |

Greetings to all!

Code:

Hi Bruno
In fvScheme I had set up gradSchemes { default none; grad(p) Gauss linear; grad(U) Gauss linear; } Today when I changed this to gradSchemes { default Gauss linear; // grad(p) Gauss linear; // grad(U) Gauss linear; } it works. I don't know why and this is strange for me. I haven't had to set up curl(U). Very thank you for your ultra fast replay and help. best Przemek |

It seems that settings: default none
in gradSchemes cannot be set up if I want to calculate vorticity with vorticity utility. best Przemek |
