Spatially Varying Viscosity #488

|
From what I can tell, the answer to this question is "no", but I wil check all the same: Is it possible to have a viscosity that is not constant throughout the simulation? Specifically I would like to vary the kinematic viscosity spatially and potentially temporarily. |

It is not well documented yet, but you can use Mesh::EnrollViscosityCoefficient to enroll a function to set arbitrary viscosity nu(DiffProcess::iso,k,j,i). |
