@tomleslie 

My original question was about how to influence U[1,6] on the shell segment not the influence of U[1,6] on the cylindrical shell!!!!

How the influence of U[1,6] on this plot?

plot3d(3+cos(h), theta=0..2*Pi, h=-1..1, coords=cylindrical, style=surface, axes=none);
plot3d(3-cos(h), theta=0..2*Pi, h=-1..1, coords=cylindrical, style=surface, axes=none);

@tomleslie 

Thanks so much.

 

@tomleslie 

Thanks,

I applied whole of the your comments, but only the first one is calculated and the other terms not calculated!!!

What is the problem?

Thanks so much

Dear Tomleslie,

Do you find the problem?

I do know sometimes the program works and next time it encounters with error!!!

Thanks so much for your help

 

@tomleslie 
Thanks.

Could you please explain in fprint about (int=%12.8e\n)?

I do know what is the problem in the new attached file below.

please help again.

Thanks

@Kitonum 

Could you please help me with the plot function as mentioned in the example file?

 

@Kitonum 

Thanks but I need some graphs like this.

I want to plot bifurcation diagrams to see saddle points and Hopf bifurcations.

@tomleslie 

Thanks so much.

According to the attached file for results that you plotted, how we can show the influence of U[1,6] on plot3d? An example of cylindrical is provided, that shows the influence of U[1,6] on the cylindrical shells. 

I want to use this procedure on plot3d (convex or concave toroidal shell ).

@Carl Love 

Thanks so much.

It is just an equation that is written in Mathematica. I want to solve it in maple only.

Because this is not related to the type programming.

Thanks

Dear Carl,

Could you please help me.

Thanks

@Carl Love 

Dear Carl,

Thanks so much for your reply.

Yes, I deleted the imaginary part of the solution.

If possible please send me your calculation in maple format?

Could you please help me in finding the result mentioned in the source file for f?

I do not know how I should solve the system of the equation to determine coefficients An. Also, I am not sure about the system equation mentioned in the source

I want to calculate the gradient of f?

Thanks in advanced

 THANKS 

@Preben Alsholm 

Thanks so much,

I have been sending my equation.

Attached pdf files show the process of dimensionless of the equations.

@Preben Alsholm 

Thanks so much.

So what is the conclusion?

The mentioned relation in the paper seems to be has a problem?

Is it correct?

Thanks

@Preben Alsholm 

Thanks so much,

I uploaded the original pdf file in the attachment.

Please see it.

Best Regards,
