Hello!

I have changed the the global character size from 12 to 14 but it is not stable. Suddenly size 12 is coming up when a try to copy a row to a another row in the same worksheet.

It is very annoying!!

Any tips????

Regards

Kjell

PDE:

(a+b)*(u_xx+v_xy)+c*laplacian(u)=0

(a+b)*(v_xy+v_yy)+c*laplacian(v)=0

a,b,c=const.  Initial:u=1/2*sin(2*theta),v=cos(theta)

Text book says: Solve by complex variable method

How to include a derivative boundry condition in pde?

diff(u(1,t),x)=0. I got 0=0

Any advice?
