Non-Newtonian Laminar Flow, user defined flow law

I am trying to model ice (non-Newtonian laminar) flow under martian conditions using a flow law used in the literature for non-terrestrial ice modeling. It is essentially a power law form but combining multiple modes of deformation that use different exponents in the power law. This does not fit into any of the pre-defined models available and it appears that in version 5.5 it is no longer possible to use user-defined functions for flow laws. Am I missing something or do I need to go back to 5.4 to do this?

Dear Claire, If you choose "Newtonian", you can set "Dynamic viscosity" to "User defined" and type in anything you like. Best regards, Mats

Ok, thank you!
