Complex Ginzburg Landau |

This demonstration solves a special form of the Complex Ginzburg Landau equation for the complex field *A(x,y,t)*:

Try values of

The most general form has a complex coefficient multiplying the derivative terms, but for ease of the numerics this has been chosen as unity. The coefficient *(1-ic _{3})* of the first term on the right hand side is chosen to make the appearance of the dynamics more consistent with our intuition on wave propagation - this coefficient can be changed arbitrarily by multiplying

Plot type *1* shows the magnitude of the complex field is plotted on a gray scale *minimum-maximum = black-white*.

Plot type *2* shows the phase angle plotted on a "rainbow" color plot *0-90-180-270-360 = red-yellow-green-blue-red*.
