Hi all,
I created an post processing utility to calculate the divergence of U. I started with the 'vorticity' utility and just changed curl(U) for div(U). Then I compile it without problem. But when I run the utility I got : Code:
keyword div(U) is undefined in dictionary "/home/ag74290/OpenFOAM/ag74290-1.6.x/run/test/system/fvSchemes::divSchemes" Code:
divSchemes { default none; div(phi,U) Gauss linear; div(U) Gauss linear; } My question: Why do I need to add this line in the fvScheme file? Thank you, Pascal |

decided until you actually use it. So when you call on any operator, it first looks for which scheme to use and then calculate the result. N |
