I am conveting ordinary differntial equations into polynomial using differential tranformed method and also after using pade arroximants for finding converge point at infinity. because differential transform cannot satisfy boundary at infinity. EQ1 and EQ2 does not built up fromt he preceeding iterations. its pade approximants diagonal value results like pade[3,3],[4,4],[5,5] and so on. i can solve this type for single equations but when  i solve coupled equations...

I have been messing around with MapleSim for a while now, and I cannot find a good way to model something such as a spiderweb. I want to be able to model a spiderweb (using something like cables), and then measure the tension in the cables, and also vibrations as they travel through the cables. Is this something that I can accomplish using MapleSim? If so, what is the best way to approach this problem? Any suggestions or comments would be helpful. Thanks. 

can i distrubute some random particle with an arbitrarity function in maple, for example p(r,theta,phi)=p0*sin(theta)/r, 0.01<r<1, 0< theta<pi, 0<phi< 2*pi. For such distribution we expect many particle in equator.

many thanks

After a few steps and derived out a formula include a hypergeometric expression

hypergeom(....)

in this hypergeometric expression, there are more than two parameters in maple for example

hypergeom(X,Y,Z...)

from some paper said G(z*q; q^f)

i am not familiar with hypergeometric series

how to substitute z*q and q^f into a formula include a hypergeometric expression.

Hi,

I'm currently working on the modelling of a thermodynamic process.

Briefly, I cool down a solution (water + polymer) from -5°C to -15°C to induce a phase separation. At the end (and after removing of the water by lyophilisation) I obtain a porous sponge like material.

The process uses a home made cooling system which can be described like this:

- A Peltier module

- An aluminium layer recovered by teflon (And also a layer of ethanol)

Hi, there, maple built-in help just has an example of Brusselator model in 1D case. But how can I intepreter the diffusion terms that Brusselator has in 2D case? Could you please give me an example of the code to run Brusselator simulation in 2D case?

Hi, i am trying to create a breakpoint on my worksheet. But i cannot press the debug current operation icon. Is there some other settings that i must press before using the button? Please help. Thanks.

Hi all. I am trying to use the Weyl character formula to evaluate some traces of Hecke operators on algebraic modular forms. This involves me having to substitute certain eigenvalues of 4x4 matrices into a polynomial of arbitrary degree (my choice).

I have created procedures that do this given the eigenvalues. Unfortunately I am having problems generating the eigenvalues.

The problem is that the matrices I am using are formed from products of matrices from two...

Hello every one,

I got an error while trying to solve numerically a nonlinear system of odes using 

the dsolve command. This error is very common,

"Error, (in dsolve/numeric/bvp) initial Newton iteration is not converging".

I tried the different technique explained in

This question was asked before but because of the curiosity, I 

bring it in the light again. We have a system of odes

restart:with(plots):

a := 1; b := .5; d := 1; omega := .4; h1 := 1+a*cos(x); h2 := -d-b*cos(x+omega);

F := Q-1-d;

de:={alpha*(diff(f(y), y, y, y, y))+G*(diff(theta(y), y, y))+B*(diff(phi(y), y, y))

+6*beta*(diff(f(y), y, y))*(diff(f(y), y, y, y))^2+3*beta*(diff(f(y), y, y, y, y))*

(diff(f(y), y, y))^2 = 0,

I created a triangle whose length of the medians are integral numbers. Please comment to me about my code.

Hi people!

I'm experiencing lags of about 45 seconds on the interface when trying to manipulate the blocks of my model. MapleSim becomes totally unresponsible when, for example, I make a new connection. It just happens with this model.

Curiously, when I disable an specific connection, I can manipulate the model with reduced (but yet present) lags.

For instance, my processor is an Intel Core i5.

Could someone take a look at it? I will upload the model on demand.
