Mathcad

I just installed MathCad 15 (M045). However, when I try to open a MathCad file, I receive the message included in the attached file.Thank you for your help

I have a complex design program written in Mathcad 14 (15). I create 3 HTML formatted outputs - each output is stored in a variable. In Mathcad 14/15 I pass these variables along with a user chosen filename to a scriptable button. The script then takes the data and writes out the 3 HTML formatted files to the hard drive, appending a time stamp to the HTML and adding an extension to the selected file names. Works great!Now the problem is that Prime 3 no longer supports the scriptable buttons and the read/write functions in mathcad will only let one write out matrices of numbers - they will not write out a string variable. I have tried to work around the problem by creating an excel component, passing in the data into cells and then adding a button to the excel component that when clicked executes a VBscript macro. The issue is that Prime 3 hangs up and does not return to Mathcad with the time stamp that lets me know the files were written out. In fact any excel component that executes V

Hi there,I'm an engineer looking for a way to automate the report generation of calculations using data from finite element applications. I'm hoping Mathcad might provide a solution.I've looked through the help files and performed various searches but to no avail. I am a novice Mathcad user.For those who aren't familiar, all that really matters is that we have a structural model which contains many 'elements'. You can think of the elements as Lego bricks to aid visualisation.Each element only has one set of properties, such as max shear, max tension etc. A table of the properties for, say, a two element model might look like this:Element_ID     MaxForce(lbf)     1                      2000     2                      2400

I see the "WriteDXF allows PTC Mathcad users to create 3D models mathematically then save them as DXF files, perfectly suited for incorporation into CAD assemblies."  But, I cannot locate documentation for how to do this.  I'm new to the community, so I may just not be looking in the correct area, but I've searched for "writedxf" in multiple locations on the site.  Is anyone using this command/feature that could give me some tips?  Many thanks, Jessica

Greetings,Is there a built-in function "IsMissing" in mathcad 14?if not, what do I have to do?

Hi,I'd like to solve the the problem on disc cam profile generation. In the disc radius, roller radius and eccentricity are the parameters. I am interested to optimise pressure angle. where Base circle radius,   is eccentricity  , is displacement function and   is velocity function.I'm not sure how to do this in MathCAD. CAn anybody help to optimise pressure angle. pressure angle should not be greatter than 30 degrees.The end goal is to optimize Pressure angle to  a certain disc radius, roller radius and eccentricity.

   Hello Everyone.           Not understand _ both are true ?                   Thanks in advance.                        Regards.

Hi there,I am currently trying to write an equation in Prime 3.1 which includes resistivity.For some reason it is not letting me put the units as Ohm-m and hence not letting me complete the equation.Has anyone got any ideas how to over come this?

WE & Fred thank you very much for answering the question, specially to WE.WE, is it possible to get the answer in the following format? Thank youHeader 1Header 2Header 3abAA+aA+bBB+aB+bCC+aC+bOriginal questionHi, is it possible in Mathcad 15 or Prime to do a vector element by element addition that takes as input 2 vectors for example,vector x = [ A,B,C ] and y = [ a,b ] and has as output z = A+a, A+b, B+a, B+b,C+a & C+b ?

I'm attempting to do a simple matrix subtraction operation and it doesn't appear to work.I just get the "Array Dimensions Do Not Match" error however as shown in the attachment, the dimensions clearly match.Not sure if it has anything to do with one matrix have double parentheses (not sure why as I didn't intentionally creat this) and the other having single.In any case, I've attempted multiple things including using the Vectorise but this doesn't resolve it.Any assistance greatly appreciated.Thanks.Wade

hello folks,I fail to find the cause of my problem.When fitting a function to measurement data, the continuous version; i.e. with x a dependent variable, it works like a charm. when I try the same piecewise; i.e. with the values from the data set, all but the last value are zero. Any clue to the whys and whats?ThanksRaikoP.S.As always, MC15 on win7 on a 64 bit machine

HelloCan somebody help me with my problem I am new at mathcad and I have this problem.Example if A is 201-300 its value in calculation is 2.65And if A is 301-400 its value in calculation is 3.68. So what i do so it calculate it correct answer.

Is it possible to assembly a global matrix from many individual local matrices?  Such as is done in stiffness matrix of a structural system?For example, if k.1 yields a 2x2 matrix with positions in regards to the global matrix 11,12,21,22.  And k.2 yields a 2x2 matrix with position 22,23,32,33 again in regards to a global position.  Can MathCAD assemble the matrix with correct positioning without building k.1 and k.2 as a 3x3 and then simply adding together k.1 and k.2?  Its simple enough when the global is a 3x3 assemble from a 2x2, but is much more strenuous when assembling a 10x10 matrix from (5) 3x3 matrices.

Does Mathcad Prime have "document properties" like in MS Word when you go to File > Info?

I have written a hardyCross subroutine per the Hodge and Taylor book and I am recieving the error value must be a vector. What am I doing wrong?

How can i set plus operator from dot to X in MP3.1?I know how to set it in MC15 but i can't find the setup option in MP3.1.

Hi, is it possible in Mathcad 15 or Prime to do a vector element by element addition that takes as input 2 vectors for example,vector x = [ A,B,C ] and y = [ a,b ] and has as output z = A+a, A+b, B+a, B+b,C+a & C+b ? Thank you!juan

Hello,Attached you can see a solve block with a system of Differential Equations.Has somebody an idea what is wrong or is it a typical Prime-problem-if then it should be fixed in Prime 4.0?I tried to solve completely without units but then i got the same error message again.I am working with MathCad Prime 3.1Thank you for your efforts.regardsVolker

   Hello Everyone.  (e^-pi)^x , solve ?      Thanks in advance.          Regards.

Hello,I run into the situation frequently where I need to select the lesser of greater of two equations.  Suppose I have equation A and equation B.  I've input say 6 values for A and B in a single column matrix and evaluated each.  I would like to define variable C as the maximum of A or B output for each row.  I attached a worksheet that demonstrates my problem.

I want to pass a table of data into Mathcad.Each row of data is like fluid_description (string), fluid_density (real value with units), fluid_viscosity (real value with units)I have succeeded in sending a matrix of numerical values with and without units, and also individual string values.  But can't seem to find how to send a matrix of strings.Also worth mentioning that whilst for now I'm using the API, in future it would be intended to migrate this to Mathcad gateway.Any advice welcome.

Hi everyone,I seem to need the help of the forum often lately... I need for test purposes to generate a sinus-wave with randomly varying frequency (and possibly also amplitude, but that is the lesser problem).  Something like an oscillator whose frequency is not perfectly stable. Or an oscillator whose frequency setting adjustment button would be slightly turned right and left randomly by a small amount.  Something like this:I attached my solution, but I am not happy with it at all. Obviously the "randomness" becomes higher and higher with the time, and for the same reason there are unwished jumps in the later part of the simulated signal.I understand that the problem is the time variable "t" in the equation A*sin(2*pi*f(t)*t) .But at the moment I can find no good simple way to correct the behaviour.Maybe I am missing something obvious  ... I will be grateful for any hint.Best regardsClaudio

I understand that the Excel component does not "know" about units of measure internally.But if want to enter the value for a variable into the Excel component in a particular set of units, how do I do it?For example, I have a variable "Power" in the MCP 3 which uses units of MW, e.g.:Power := 10 MWIf I evaluate Power in MCP 3, by default, I get the following:Power = (1 x 10^7) WAnd 1 x 10^7  is also the value I get in the Excel Component if I create an Input Expression and set it equal to "Power".But, if I want to have the value in the Excel to be 10 (i.e. MW), how do I make that happen? Is there some way to implement the Input Expression so that I get the value in the correct units?Thanks in advance.--Doug
