PDE with 2 variables

Please login with a confirmed email address before reporting spam

Hey,

I want to solve a PDE (can be written f.e. in convection diffusion form (cdeq)) with 2 variables a and b.
Both variables depend on each other: If a>0, then b=1 and if b<1, then a=0.
Have you any ideas how this problem could be solved?

Thank you in advance!
