hi..when i use rule [for] in maple code i encounter error'''''

Error, (in dsolve/numeric/process_input) input system must be an ODE system, found {f1(x), f2(x), f3(x), ApproximateInt(-4*cos(theta)^2, theta = 0. .. 1, method = simpson), ApproximateInt(4*cos(theta)^2, theta = 0. .. 1, method = simpson), ApproximateInt(8*cos(theta)^2, theta = 0. .. 1, method = simpson)}''''''''

please help me for remove it

i want for different beta for example beta=0, 40 and 80 this lines will computed three times  

 ''with(Student[Calculus1]); a1 := ApproximateInt(g1*g1, theta = a .. 1, method = simpson); a2 := ApproximateInt(2*(g1*g1)+3*g1*(diff(g1, theta, theta)), theta = a .. 1, method = simpson).......................''          

 by {for i from 1 by 1 to 3 do } and final gain ''ITRA_1_W[m] := eval(fy33*g3, fixedparameter)'' that have 3 amount.

when i use  rule {for i from 1 by 1 to 3 do ...  }   integral not computed and showed for example:::

a1=ApproximateInt(4*cos(theta)^2, theta = 0. .. 1, method = simpson)!!!!!!!!

thanks..

I read a posting by Mr. Stephen Forrest on Thingiverse about using the exportplot command to export a 3D plot as a .stl file. I have a 3D printer and need the convert the plot from the Maple file into an .stl file.

Here is the posting I am referencing:

Thingiverse/3dmodelimportexport.pdf

I was able to follow the commands successfully in the referenced paper for a hyperboloid or revolution that I plotted in Maple - it was very helpful. However, I could not figure out how to access the temporary .stl file that was created so that I could open it using my 3D printer's software.

My question is: Once I execute the "exportplot(stl, hyprev)" command that I inputted, how can I find the file in the Temporary Directory in order to open it from the software I use for my 3D printer?

I would appreciate any further details you can provide for accessing the temporary .stl file I created in order to be able to print the object.

Thank you!

I use Maple on a Surface Pro 4 tablet and the math input panel does not work with Maple.  This would be a great feature to have.  Or does anybody know how to get it working?

Maple Worksheet - Error

Failed to load the worksheet /maplenet/convert/Sc.mw .

Hi everyone,

For my first question, I am looking for some help about the following. I have the opportunity to run a worksheet in parallel on a cluster of sixteen workstations, each one endowed with twelve CPUs, through the GRID Computing Toolbox. However, I have troubles concerning how to do that.

I join the worksheet at issue: abmm_ma_1.mw The aim is to run large-scale numerical simulations of a dynamic system, depending on the values given to the initial conditions and to the parameters. The worksheet is organized in four execution groups:

1. The required packages (combinat and LinearAlgebra).
2. Calibration of the parameters and initial conditions.
3. The system, which is embedded into a procedure called SIM.
4. The activation of SIM, whose outputs are nine .mla files, each one being made of a real-number matrix.

The truth is, I do not clearly see how to modify the worksheet with some elements of the GRID package. Besides, the cluster operates under HTCondor so that running the worksheet requires beforehand the creation of a .sub file. This should be done in consistency with the aforesaid modification.

Any help is welcome, thanks a lot.

Hi,

I'm trying to export a plot using the open maple api but it looks like open maple API doesnt support certain specific features.

Eg. "Export(\"images\\\result1.gif\", plot(sin(x), title = \"The sine function\", thickness = 3, gridlines=true));"

Above works fine when executing in actual maple application (i.e. correctly exports with gridlines) however doing the same via open maple api it does export the chart but not the specified gridlines.

Had the same issue when setting axis options to show log instead of linear. 

Did anyone else get this? Is this a known issue with open maple api? Is there workaround available?

Thanks,

Bidur

Recently, entered a engineering graduate program and will be taking a graduate engineering class in my retirement.  In our Into classes we reviewed engineering math through ODE. In the second class, we performed some numerical methods using MatLab with a small introduction.  My formal Math wass in the 1980s, but now have to fire it up for a Engineering Analysis using Michael Greenberg's Advanced Engineering Mathematics, 2nd which has Maple imbedded code and directions.

What would be my assignment for getting up to speed with using Maple to solve algebraic-symbol-programming problems? For instance, which tutorials in what order, or webinars? i think I once had Fortran 77 and remember zip.

Appreciate any good advice.

i tend to study a particular function each day, and noticed that the CAS literally ignores me when i as for an evaluation of the mellin transform for the lerch phi function. i just assume there to return an error if the function has properties that do not satisfy the criteria for a particular transform, in this case, null, it just pretends i didnt ask.

Assuming the maple kernel hasnt evolved conciousness and has decided to hate me im guessing someone else has run into similar circumstance.

Hi,

I am trying to download some MapleSim Robotic models from the Maplesoft website but I have 'Invalid File Format' error. Could you help please?

Let a non-planar non-self-intersecting closed polygon in three dimensions P  be given, say
with(plots): with(plottools):
P := polygon([[0, 1, 1], [1, -1, 2], [3, 0, 5], [1, 1, 1]]):
How to find the minimal surface  with the boundary P?
There is no chance to find the solution as a closed-form expression.
Thus, the numerical solution (or/and a triangulation which approximates the minimal surface up to the given accuracy) is required.

how i can find order of convergence of newton method by expanding taylor series?? plz send me code???

how we can solve an ode with boundaries by using RK4 and any other technique??

how we can solve an ode with exat soltuion n calculate the unknw constant which aries after solving an ode.???

Dear forum users/ admins, I have some questions regarding the wind turbine vibrations model based on the MapleSim gallery. I am a new user, went through some tutorials and am currently trying to understand how the system works.

I will try to deliver my questions based on the pictures shown below:

 1. After running the model, 2 results were shown. One is "Latest Results" and the other is "zeta=0.01". Based on the images above, there is a comment that the result was dated Feb 14 2013. Is this the result on which the day the model was created? If it is, is it programmed to be in the result file everytime the simulation runs?

2. If I untick "zeta=0.01", a red graph appears, which says Latest Result. But the graphs are not labelled. How can I label this graph in MapleSim? 

3. I would also like to ask, what type of vibrations are occuring in the model, and what does the Deflection-Time graph means. Why does the deflection occur highest at 120s and then drops? Is it because the tower becomes stabilized after a while?

4. I understand that the model is run by a signal and fed into a speed component. May I know what is the f(critical) is, and how it affects the system?

5. From the Ramp signal, there is a "height" value. The pre-set value is 10. After changing this value, to lets say 50, the maximum deflections occur at a an earlier time as shown in the figure below:

6. I would like to understand how does the ramp affect the maximum deflection time that occurs.

Thank you very much!
