Rotating frame simulations do not work in the steady state solver

2

Jens Kunze has found that rotating frame simulations do not work properly in the JFNK. I suspect this is just a matter of adding the blk.omegaz arguments to the relevant...

Restarting a simulation with residual_interpolation_order = 1 actually uses config.interpolation=2 for computing the first preconditioner step. In very unstable flow conditions, this can cause a crash.

Currently ```lua-modules/globalconfig.lua``` and ```lua-modules/nkconfig.lua``` return a warning ```The field '%s' cannot be set in 'config' table.``` if the user mis-types a config variable name. Per discussion on 19/06, this warning...
