Hello Everybody,
I am working on vortex shedding of a cylinder in cross flow. I want to plot the contour plots of vorticity in z direction so that i can see the positive and negative vortices. So i used the utility vorticity in Openfoam to calculate the same. Now while plotting the contour plots the only thing available is magnitude of vorticity(magVorticity in Openfoam).Therefore I am not able to see the positive and negative vortices. Please let me know how to plot the contour plots for vorticity in z direction. Also for reference I have attached the countour plot of magVorticity. Any help will be aprreciated. Thank you very much. |

Hii Snehal,
The vorticity utility gives vorticityX,Y andZ directly. So i don't think you should have a problem anymore. Tarak. |

Hi Snehal,
You can calculate the x, y, z components of vorticity by "foamCalc components vorticity". Then you'll be able to see vorticityx, vorticityy and vorticityz in ParaView. Cheers! ZZ |
