[CIG-LONG] Low viscosity material around dike

[Guillaume.Duclaux at csiro.au]

Folks,

I'm currently out of office and I didn't bring my scaling scripts with me... The NewNewtonian rheology in Gale implies some scaling (in order to obtain an effective viscosity of the order of one), you can't directly use values from the literature.

I'll detail the scaling for each parameter in the NonNewtoninan constitutive law as soon as I can acces my machine.

Cheers

Gilly

I got my numbers from someone else (Guillame?), and I do not know what
he was assuming.

Did you try submerging the dike even further?  Eventually, you should
no longer have a dike hill.
