This is a substantial change because the viscosity is now assumed to be isotropic in 3D, eg We don't have an anisotropic viscosity anymore (I don't think), instead our design us to use a closure tuple for that situation, in which there are separate horizontal and vertical viscosities. You could edit the source code to achieve your goal though. |

Hello,
@francispoulin and I had a question about using the Smagorinsky-Lilly closure scheme but specifying a different vertical and horizontal eddy viscosity separately where each would use its respective grid spacing in the scheme as the filter width.
Given that this is supported when specifying a constant eddy viscosity (constant anisotropic) I imagine it may be supported out of the box with any other closure and I just can not find an example of this.
If this is not supported out of the box would it be that difficult to implement myself? I am having a bit of difficulty finding the code I would need to edit, but I will hold off until I know this isn't already a feature.
Please let me know, Thanks!
