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.

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.
