A difficult PDE problem.

Please login with a confirmed email address before reporting spam

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
