Abstract
The form of the steady state PDE system solved by PDE/PROTRAN (Section 1.5), is: where R is a general two dimensional region and
\(\partial {R_1}\,and\,\partial {R_2}\) are disjoint parts of the boundary. The time dependent and eigenvalue problems will be studied in Chapters 4–6.
$$\begin{array}{*{20}{c}}
{0 = {A_x}(x,y,u,{u_x},{u_y}) + {B_y}(x,y,u,{u_x},{u_y}) + F(x,y,u,{u_x},{u_y})\,in\,R} \\
{u = FB(x,y)\,on\,\partial {R_1}} \\
{A{n_x} + B{n_y} = GB(x,y,u)\,on\,\partial {R_2}}
\end{array}\,$$
