Mathcad

When you purchase PRIME the only thing that worth to you is that you get MC 15 ... You can put PRIME in the drawer of the your desk and start to work with the real software... MC 15. Thanks to god that we get MC 15 ... (As a converting tool ... But who want to convert his documents to useless PRIME ?)There is no way to buy only MC 15... This is a very strange way to promote a new worse product ... Remember, PTC can force us to have PRIME in the drawer ... but never force us to use it !!!I hope MC 15 will live forever ! - Or at least until PTC will wake up ...SHEMY

I have another question. I want to make graph about my data.x-axis will be used by right data in the picture. y-axis will ble used by left data.thank you for reading my question. (I attached my file)

PTC Mathcad is adding support for Windows 8.1 operating system in the Prime 3.1 and 15.0 M040 releases, while at the same time dropping support for XP and Vista. In addition, we will be retiring all support for versions 11-13 on April 1st, 2015. Please see this blog post for more detailed information.

Hello. I know there was a compatibility issue with W8 but was just wondering of that has been resolved? I would like to run my copy of MC13 on my laptop but have been forced to use older, MC2001 instead. Of course I can't open files created in MC13...Thanks

I have installed Mathcad 15 on my computer with a trial license but it will not open. I tried installing MSXML 4.0 but this did not resolve the issue. I am operating windows 8, 64bit.Do you have any suggestions?

In this file I used Mathcad to simulate a pump curve.  However, one needs to be careful when doing this because pump curves cannot be simulated beyond that given by the pump manufacturer.

I am a korean so I can't write well about my questions. But I will try to write.I want to express 'Loop'. Let's we suppose two equations. One is X=Y^2+2Y+3. The last is Y=X^2+3X+5.I can find adequate value by finding convergence between X and Y. But I can't express in MATHCAD. I think I need to use 'While' to express..How can I express it to use 'while'?

UPDATE 2014-10-06 (rev 3):  I am finally done with NGAS (I think).  Over the weekend, I developed programs to size service connections to meet both the pressure and velocity criteria, not just to meet the pressure criterion as in Revision 2.  Here is what is now in the .zip file:Lusk_NGAS_Distribution Systems.mcdx & .pdf — This worksheet calculates flows and pressures in a natural gas distribution system consisting of a multi-segment Main Line and up to two service connection branches at each Main Line juntion node.  Design pipe sizes are found by trial and error, specifically by editing the pipe data until the design criteria are met or met close enough for your purposes.Lusk_NGAS_Unit Conversions.mcdx & .pdf — This worksheet shows how to convert natural gas demands and flows from one set of units to another and discusses ways to determe the peak demands to use for design.  This worksheet functions as an appendix to the other seven worksheets.Lusk_NGAS

This is a file that was developed and used in a court case involving drainage.  In this file I go into some depth in using the Rational Method to compute the peak flow from a catchment.  I felt that this catchment was made for the Rational Method. 

A dynamics problem involving 3d motion.  I solve the problem using vector arithmetic rather than vector diagrams,  which would be quite difficult.  In my opinion getting students use to daily use of matrix algebra makes doing such problems easier.  The problem is that the student has to learn to "trust the math" rather than a visual vector diagram.

Has anyone figured out how to use the OCDB kit? I am in the process fo converting from MathCad 15 to Pirme 3.0 and there is quite a learning curve on this. Does anyone have example files that they can share.

The attached contains an expression I wish to use in a solver to determine x-amount of constants (the Q's) from a system of an equal amount of equations and unknowns (the constants). The problem in mathcad arises when I'm using multiple (two) arrays within the solve block.

Hello one & all-I did a Mathcad course a few years back but have never actualy used in since-I remeber during the course that you could solve equations, for example, if 2x + 3z=y, find the value of x?Moved offices and have lost my course book( know it's here somewhere!) but any tips & tricks on how to solve equations-remember you had to type given in the math page but twasa looong time ago! Cheers all!!Graeme

Hi,First time posting on these forums, been reading around for a couple of years though.I would like to create a plot of 4 functions (let's say it's different pressures depending on a variable, h). I've done this in the appended example.However, I would now like to plot only 2 of the functions if a variable, say "condition", is =1.How can I do this? I have tried adding an "if" statement on the y-axis of the plot itself, like this:----f.1(h) if condition=1----, but I get a critical error when doing that, and the plot goes blank.I'm using MathCad 15.Any suggestions are appreciated,Thank you,Hampus

Does anyone know if you are able to convert files created in MathCad Prime 3.0 back to MathCad 14 format. I have the converter that allows me to convert MathCad 14 worksheets to be used on Mathcad Prime 3.0, but my colleagues all have MathCad 14 and therefore can't open files that I create in prime.Any help would be appreciated.Thanks

I know Lusk recently posted some files on this, but it was not really what I was looking for. I am trying to be able to generate a table of thrust forces at select junctions in my pipeline. Currently, it is set up for one pressure, but I want to evaluate multiple scenarios in this sheet. Pressure for steady state, test, surge (e.g. 20, 50, 35). The middle one only has a static component, but the others require analysis. The other problem I need to figure out, may be a programing issue, is the restraint for a dead end. The X component using 90 degrees is correct; however, you plug in 0 for your angle and the result is 0. Functions, programming, etc. are all fair game. I'd like a CSV dump to send to a spreadsheet when all is said and done. Your help is greatly appreciated in

Greetings to all, my problem is as follows: Having a main table, I require to extract certain values ​​in the same to form a new matrix only data of interest. As a picture is worth a thousand words, the following figure try to explain what I try to do: I have tried to get it using programming, but as I am new to using Mathcad I think I have tangled more and I get an error:Hope you can help me, thank you very much for the help

Is there a code to calculate the determinant of square matrix by gauss elimination method ?thank you

I'm looking for fatique analysis on metals .. think statue of liberty .. all kinds of structures . Thanks

Is there a way to convince mathcad optimizer that your really serious when you want all the entries of an optimization vector to be positive?

I was doing some reseach on what happen to the ComputerVision CAD program. It appears CV bought the CAD program Prime Madusa. CV was in turn purchased by PTC. Maybe that is why MathCAD has been renamed Prime.Cheers

Hello Im new to mathcad prime 3.0 and im wondering what software to use to draw circuits and then insert it into mathcad to show what im doing, or if mathcad has build in tools to draw circuits. For instance if i do source transformation and i want to show how the circuit look after the transformation is done, how can i draw the circuit and put it in mathcad?. Thanks

Nichols Chart in pdf format, for those who use later versions of Mathcad 14 stud. edit.If anyone has suggestions, they are welcome.Thanks.
