Mathcad

Hi, I have Mathcad 13.1 that I used to use with Windows XP. Now my computer has windows 8 and I want to install MC13 onto it. I tried it but it doesn't properly install on Windows 8. Is it possible to install MC13 onto Windows 8? Thanks. Mark.

Hi..The Excel calculation given below in each step needs to check the current and stroke and import the force value from mathcad.The Force thus obtained will give the current for the second step, which along with the corresponding stroke value again the force has to be taken from mathcad.Is it posiible to automate this process using Mathcad by reading the excelsheet?I have attached my worksheets herewith.

I'm taking Jason Hafner's edX course Waves and Optics https://www.edx.org/node/3261#.VF-6xfnF-So .  I've been trying to use Mathcad Prime 3.0 to solve the various problem sets.  The ability to control units automatically is a great advantage although sometimes this makes you think hard about making equations dimensionally correct.  Recently I tried to solve a problem with the symbolic "series" command.  I had mixed success.  Here's the problem.We are taught that any problem  f(x) = mass*d2x/d2t has a hidden form -k*x = mass*d2x/d2t which is Newton's Law for Simple Harmonic Motion (SHM) of a spring.  If f(x) is non-linear, i.e., it has terms like x^2, e^x or sin(x), we can linearize it close to an equilibrium point using the Taylor's series for f(x). For SMH problems the equilibrium point is usually taken at xeq where f(xeq) = 0.To linearize we are interested in only the first two terms of the Taylor's series:Since f(a) should equal zero, and 1! = 1, w

Hijust looked over some old custom functions from Tom Gutman.He sometimes uses substitute in his functions, but I cannot fiugure out how he types it IN the programm.looks something like: if I try to explicitly type subsittute (ersetzen) it gets interpreted as a variable, if I use the symbolic -> subsittute it gets writen besides the funvction-definition.Cannot figure it out for MC 15 and MCP3?What's the trick?Need this to define a gradient function in MCThnkxWerner

I try to chang "vector" But I am seriously having a problem. This is a problem that I feel difficult.I want to get left values, not right.But If I use "vector", I get right value. it make me sad...I want to get advice

I want to stack all 100 columns of a 1000 x 100 matrix to form a vector with 100,000 elements.

I can get total QT if I define v, theta to any number.But I want to get total QT that it include v, theta as "variable"I search for method with my book, but I can't search for it.so I posted this site to get advice. could you help me?

Hi,This could be more of a conceptual question than mathcad probelm...Here in this file, I have a set of equations representing a feed back model. According to my what i am expecting with the graphs.. like the N.s/c.s graph. the N.m/C.m graph should also be constant over time without fluctuating over time.. I am not sure what causes this... can any one help me figuring this out?

Hi,I'm having trouble with units when using exponentiated variables. I'm trying to assign a variable a value (fck) while having another variable depend on the first one (fctm). It works fine if I only multiply the first variable with a constant, but if I also try to exponentiate the first variable my units (MPa) get messed up (see fctmERROR). However if I replace the first variable with the numerical value I assigned to it my units works as they should (see fctmWORKING).Trying to forcibly remove the messed up unit only breaks the whole thing (fctmERROR2).I have attached an image to better understand the problem:Also attached is a file with the error in question.Im using MathCAD Express Prime 3.0 F000 (2013.09.12.003/3.0.0.194) running on Win 8.1 x64

HiI'm trying to make a 3D plot, but gets the error "The function did not evaluate to a pure real value".I don't understand this, since the function seems to work just fine, when I enter values into it.

A few months ago my office equiped me with a "tablet computer"--in this case a Dell Venue Pro, which is functionally equivalent (more or less) to the better-known Microsoft Surface Pro. I upgraded to Prime 3, and eventually got it installed and licensed. Then the trouble started--it will not work on the road, because of "invalid license."After a lot of effort, the problem was tracked to the fact that these computers do not have a resident Ethernet adapter. That adapter is in the docking station that I use when in the office. The license is keyed to the MAC address of the Ethernet--i.e., to the docking station hardware. So I can use Mathcad on the road as long as I carry the docking station with me! Kind of defeats the purpose, no?I have worked out some alternatives with PTC support but none of them are practical or accomplish the flexibility I expected. That is one problem. The other problem is that PTC does not state this as a requirement of Mathcad usage.Just another example of PTC's

Anyone has a script to preserve the state of a checkbox when it is closed then reopened?I've seen a script for a listbox here: http://communities.ptc.com/docs/DOC-1379 but no checkbox. Thanks

Hello PTC developers, I think this has been discussed here in 2012 concluding that it is a bug!. Now in 2014, any update on when this is going to be fixed if it is going to be fixed at all?In my case the first column read OK except for the first row. The row looks is shifted left with the first value missing. also the headers get shifted right. See attached sample.The file is read well using 'file input'.It's a shame as READCSV & WRITECSV can be much more handier than using 'input/output file'.Many thanks,Ahmad

Friends,after defining f(x,y): x / y , I tried to plot as an 3D chart.Unfortunately, that's not possbile and resulting in an error message.

Way back in the days of the Collaboratory there was a thread http://communities.ptc.com/message/45030#45030 discussing how to get longer animations beyond 999 (or 9999!).The main point is that the dialog box is sized in one (microsoft) way and the characters being typed in by some (microsoft) font size. As the versions have come and gone the available space for the ### characters has reduced, limiting the animation length.Unfortunately the pictures have been lost, so I'm wondering if anyone knows the right settings for changing the screen DPI (if this is what is need) to get a bigger dialog box, and also to change the system font that Mathcad is using (to something smaller) so that I can get at least 9999 (four) digits of animation.Ideally I'd like to be able to animate at regular display DPI, yet get at least 1100 FRAMES (i.e. enter 4 characters in the dialog box)I'm using V15M030 on XP (home) and on W7 (work).Philip

I have an error by using Minimize & Maximize in Mathcad 15.But all is OK in Prime 3Why?

I practiced integration. First picture is a example that I practiced After practicing, I applied to my work with same method. But I got error. I thought why error is generated althogh the method is same. I can't know.

Hello PTC community, thanks for taking your time to check this post out. I dont know if mathcad can do this but im pretty sure it can for what Ive seen. I want to make the sum of multiplying a component of a vector with a component of a matrice in an especific column, then with the next component of the vector with the second row in the same column and so on. Details are attached in the document. Thanks for all!   PS. If you are familiarized with chemical engineering, the problem I want to solve is a multicomponent destilation tower with the rigorous method ( I think its the Amundson-Pointnen method)

Hello I recently studied about mathcad through book named "Essential PTC mathcad Prime 3.0"I saw half of the book becasue I felt get experience that I need to study basic thing.Although I studied for a week about basic, I couldn't understand "integration"so I want to get advice.And I wonder that it is possible to change "range" to "vector" about all my work.I guess to need to change "range" to "vector" in order to finish my work.

Hello,My program calculates several series of input data. I want to store all the outputs in an excel file. Is there similar function to "Appendprn" for excel file?Thank you.

Hello my friends,I know that solve block doesnt work with ranges, but a good friend gave me an example in the worksheet im going to insert(he has solved me a lot of doubts and kinda feel ashamed to bother him again). If you could explain me that way of solving the range, or if you have another way to solve it , it would be great. The example is right after calculating the K matrix, the problem i want to solve is down the bottom of the sheet. Also if you have any suggestion to simplify my worksheet, it would be great.Thanks for your time, I hope everyone have a great day!

Hello AllI am new to mathcad and I am working with the minimize function to get an appropriate value of A to get the minimum torque.I have given torque as an objective function.I have a few questions on this.1.I am not sure where do you place the objective function in a mathcad worksheet?.2.Also is it permitted to use an If statement inside a solve block?I have attached my worksheet as it is giving me an error

Hello and good rest of the evening.I'm having a trouble with plotting a function (pressure distribution in a hydrodynamic film bearing).I know how it should approximatly 'look' but am not getting the correct shape.I've of course used the help etc. but can't seem to find out what the problem is. I've attached my mcdx file.This is what I get: and this is what I should be getting, approx.Best regards Alexander

Dear PTC Community,for my studies I have to analyse the Lotka-Volterra ODE System. Now I want to use some plot like the following:There you can see the Direction Field of the ODE in a phase plot. The standard equations are like:Also I found the invariant of the System:Question is: how to make such nice looking direction field plot? From which equation is this going out? I am using Prime 2Thanks so farPatrickPS: I come across thishttp://communities.ptc.com/docs/DOC-3503but dont know anything to do...
