A difficult PDE problem.

Hi, everyone
I have a problem in PDE that there are 2 two equations with different solve region.
the similar problem are:
du1/dx=x+u2
u1=10 when x=0
u1=30 when x=50
du2/dm=m*x
u2=0 when m=300
u2=u2 when m=800
Then how to handle it ?
The above are not my real equations because they are very complex. So I build a similar simple ones.
Thank you!

Hi
have you read the book of Zimmermann ? he gives some nice examples on solving PDE's with COMSOL, see the book link on the main site
