Viscous Methods

The available viscous methods are:

• HK2003 documentation: Steady state olivine flow law from from Hirth and Kohlstedt 2003
• HZK2011 documentation: Steady state olivine flow law from Hansen et al., 2011
• xfit_premelt documentation: Steady state flow law for pre-melting viscosity drop, Yamauchi and Takei, 2016.
• BKHK2023 documentation: steady state solution for the dislocation backstress model of Breithaupt et al., 2023.

All of the methods require the state variable structure, VBR.in.SV and flow law parameters are stored as substructures within VBR.in.viscous.(method_name). See documenation pages for more detail.

Additionally, see the documentation on the Small Melt Effect for relevant discussion and parameters.
