@Markiyan Hirnyk 

hi.for gain faster result i  assume that n := 7  and obtain result for two case.

please see two case witch attached as file belowanother_result_(1).mw

another_result_(digite15).mw

@Markiyan Hirnyk

thanks. i tried with 15 digits and will say  you the result ...

@Markiyan Hirnyk 

is another way for gain result faster? may we use another method  such as Runge-Kutta thanks?

this method need to a long time for driving result

@torabi 

is possible any one help to me?

@Markiyan Hirnyk 

The equations and variables are presented as Maple  input in attached file below

solve_nonlinear_governing_equation.mw

@Markiyan Hirnyk 

maple code was reformed...thanks

FSOLVE.mw

@Preben Alsholm 

thanks...

@Preben Alsholm 

why Y is not apply on matrix and shown in final result?

@Preben Alsholm 

thanks.i apply your good comments but now i have a problem for integral.please help me

thanksmaple2.mw

@Carl Love may i solve it in mathematica or matlab?

 

@Preben Alsholm 

thanks ..whole boundary conditions attached as figure below.

perhaps i have error for writing them!!

please see them

thanks..

@Carl Love 

thanks..i correct program which reload again.really  f3(x)*h=w(x, theta)2D.mw

this equation due to this terms are nonlinear

""""""400/((1-W(x, theta))*ln(10-10*W(x, theta))^2)-500/(1-W(x, theta))^4"""""

thanks

@Preben Alsholm 

L := 1/500000000

value of L was defined in code (restart; Digits := 30; L := 1/500000000       .....  )

 

@Preben Alsholm 

hi.due to  comparison the result i decided that remove nonlinear terms.because the result which is obtanied , not mached with correct result.major problem for me is  initial guess and dependent eginvalue to approxsol in maple!!!!!this makes that i donot know which answer is correct!!

@Preben Alsholm 

hi.thanks.is there analytic solution by removing non linear term.if possible please help

thanks a lot
