Hi,
In my 2D model,the governing equations are

.
The
and
are the variables I want to solve on the whole plane.Other variables ,
are all known.The direction of the magnetic field is normal to the 2D plane.
And I want to solve this two equations together, which means the plane has two governing equations. And the coefficient Form PDE is very convenient to define both equations.But the coefficient form PED is overriden,I can‘t add another coefficient form PDE.This bothers me a lot.
your kind help is very much appreciated.
Thank you very much
