Hi
"red" means formula typo, this is an error, "orange" means units error, that is a warning, but before you solve an orange error might come from an undefined variable.
I do not have the mwp physics so I cannot tell about that variable (it might have changed name or its a typo. Turn on the internal equations: Options preferences show tab and look in the list of the sub-tab of your physics nodes

Good luck

Thanks,
it is calculating.. so the variable is OK but it is the unit mismatch which is responsible for the orange color.
Still my convergence plots have some plateau at 10E9 and when I am lucky at 10E7. (surface wave microwave plasma)
I do not know where to look for answers.
Of course it is multiphysics, so there is a close interdependance between E-Field and e-Density,
so each small modification makes the whole turn around again and again..
does the segregated solver do this physical separation:
simulates one set of variables until steady-state
and then switch to the next set of variables?
do I define which variables are fixed for one segregated step? so if I choose them intelligently that is what this type of segregated solving does: solving one physics after the other..
taihen desu,
(difficult it is the simulation)
