### Weyl scalars from null tetrad...

April 07 2016
0 7

hello dear,

I was intersted in finding Weyl scalars for a given metric, would be really helpful if anyone can give me an example of how to find a Weyl Scalar for a given metric or set of null tetrads using Debever formalism in Tensor package(more specifically, how to define h in debever formalism for a given set of null tetrad or for a given metric).

Regards,
Suresh

### How to use .mws in Maple Player?...

February 24 2016
2 6

Just starting some work on numerical engineering solutions by going through a workbook, which includes a Maple Document on CD (with one index.mw and several .mws files).

As I don't have acces to a Maple system, I downloaded Maple Player. However - Maple Player will only accept .mw and .mwz files(at least that shows up on 'FILE>OPEN'); so trying to open an .mws file results in - NOTHING. In your forum I found some information that .mwz is a nonpublic Maple format !?...... Now I don't see a way to work with PLAYER. Isn't PLAYER meant for exactly that scenario - sharing MAPLE worksheets ?

So - what to do ?

Thanks for some hint,

### Set plot zoom factor using command...

February 21 2016

Hi,

Can anyone please suggest a way to set the zoom factor for a 3D plot from the plot commands or using DocumentTools or in some other way that doesn't involve the interactive tools?

What I'm trying to achieve is the following:

I'm developing MapleCloud worksheets for a course I'm teaching and want to give my students several 3D plots to interact with through their web browser.  When I make the plots, Maple determines the scaling so that boxed axes with labels will fit in the area of the plot component.  However, I'm making plots with axes=none that look better at a higher zoom factor (the corners of the unseen boxed axes would be out of the plot area but all the plot components still fit) and I'm keen to create the plots that look like this if possible.

My ideal solution would be for there to be a zoomfactor option for the plots[display] command or to be able to use some code like SetProperty("Plot0",zoomfactor,1.25) but I haven't been able to find a way to achieve this.  The closest I found was setting the viewpoint option, but that locked the view, preventing rotation, and I want to just set the initial view.  Is there some other method I haven't found?

### Displacement in elasticity...

Hi

I've this equation ,what is displacement,

U := sum(C[i]*lambda[i]*h^2*M*(C[13]+C[55])*exp(Z*lambda[i]*M)*cos(M*x)/C[11], i = 1 .. 4);
But when I used the data ,I do not get the right result

the datas are

h := .25;
M := Pi/L; L := 1;
E[3] := 1; E[1] := 40; E[2] := 1;
1
V[13] := .25; V[31] := .25; V[12] := .25; V[23] := .25; V[32] := .25; V[21] := .25;

G[44] := .2; G[55] := .2; G[66] := .2;

G[13] := .5;

C[55] := G[13];

Omega := -2*V[13]*V[21]*V[32]-V[12]*V[21]-V[13]*V[31]-V[23]*V[32]+1;

C[11] := (-V[23]*V[32]+1)*E[1]/Omega;

C[12] := (V[13]*V[32]+V[12])*E[2]/Omega;

C[33] := (1-V[12]*V[12])*E[3]/Omega;

C[1] := -.2596702449; C[2] := -2.411545729; C[3] := -0.6051254981e-1; C[4] := .4085627399;

lambda[1] := .6891428810; lambda[2] := -.6891428810; lambda[3] := 9.177422410; lambda[4] := -9.177422410;

could you help me plase

### How to write to a file in MAPLE PLAYER?...

August 31 2015

I have been unable to successfully open a text file for writing in MAPLEPLAYER, whether it is requested in the startup code section or via a document tools button.  Is there a way to write to a file in MAPLEPLAYER?  It returns a "no write access" statement.

The write works perfectly in MAPLE 2015.1

### How to use my module in Maple Player ?...

July 24 2015
2 9

I have created and saved a MAPLE module in an .mla archive. The module contains three procedures A, B, C, where

A calls, B and C.

Once the module library has been loaded, A acccepts inputs and generates outputs.

Is it possible to create a MAPLE player worksheet which calls the module and share it with a Maple Player (only) user, so that they can then supply the inputs and observe the outputs from A using the Maple Player programme components?

Can anyone help?

### Lock some contents for viewing...

June 23 2015
1 2

Maple 18 and MapleNet 2015.

Show/Hide Contents allows one to hide certain elements of the worksheet. Is there a way settings there (or somewhere) can be locked so that another user is prevented from seeing certain elements of the worksheet?

Rationale: As an example: I'd like my students to use Maple Player to interact with a worksheet, using Maple Component GUI elemnts. I do not want them to see all the code behind that, and in fact explicitly want to rule them seeing some function definitions. I can hide "input, output" when I create the document, but under "View" in Maple Player, the intrepid student could always unhide that and see the code.

### MaplePlayer support Maplets?...

June 23 2015

I'm using Maple Player 2105, Maple 18 and exploring using Maple/MapleNet/MaplePlayer for education.

Is the following correct? In order for a my students to access a Maplet, they would need a full version of Maple installed on their system (Maple Player would not be enough) I couldnt get Maplets to work with Maple Player, but maybe that's just me.

(I do not have the \$ at the moment to go the MapleNet route)

### Difference in Explore between Maple and MaplePlaye...

June 19 2015

My code works in Maple (18.02), not Maple Player (2015.1). Much headache ensued.

I've isolated the problem in a toy form:

Defn := proc (scaleby)
whattype(scaleby);
end;

Explore(Defn(p), parameters = [p = [1, 10, 100]]);

In Maple will return "integer" for any value of p selected in the combobox.

In Maple Player returns "string" for any value of p selected in the combobox

Is there something I'm missing here? Is Maple Player not backwards compatible to versions of Maple prior to 2015?

My understanding is that Maple Code should export without headache to Maple Player. Is this a solid understanding?

Thanks for helping out a newbie!

### MaplePlayer App...

I have downloaded MaplePlayer on my iPad.   I see that it comes with a number of "pre-recorded" programs that it can run.  Is there a way to have it run a Maple worksheet that I have written?   If so, how do I use this app to open an existing worksheet?

Also, are there any plans for this app on the Android platform any time soon?

I'm trying to create a small app for Maple Player to graph solids of revolution. When I run the app in the desktop version of Maple T.A it works, but when I move it into the Maple Player App it crashes. Any ideas?
