I must solve A*(Uxx+Uyy)-B(x)*Ux=0 , where Uxx means ssecond partial derivative of U on x and U(x,y); Ais constant and B(x) is function of x! The eq has BC dU/dz=0 and dU/dy=0 IC U(0,y)=1 for -1<y<0 and U(0,y)=1 for 0<y<1 in Mathematica!(adsbygoogle = window.adsbygoogle || []).push({});

Can anybody help me with some example? Thanks, Jan mail: jan_golob@email.si
