Mathcad

Why are these units are not equal? RPM - revolution per minute.

One standard for texts and "dead" formulas now is pdf (Adobe).We can free download Adobe Reader and open documents (in Internet).Now Elsevier/Knovel is working on same standard for "live" calculation.In future we can free download ??? and open documents with "live" formulas: input new data for formulas and see new answer!I think Mathcad (Express) can be this ???. I would like to have some as Mathcad Reader PSNow I am working with one team with this ??? - see please http://tools.knovel.com/ie/Help/contributors.htm

I tried running two downloaded PDE examples of mathcad 11 in mathcad 15, but both examples cannot be in good running, either intolerable time-consuming, or error informations on function-call .how can I modify the codes to run them smoothly on mathcad 15?

Is it an Error or one property of Mathcad (as in BASIC or Pascal, not C)?If 2>3=0 why we must check one more second operand!?

Hello. I need to transfer my single Mathcad 15 licence to a new PC.Unfortunately i lost Product Code Card that is nessesery to renew licence for a new PC.I still have originally generated licence files on old PC.What can i do now ?Kind Regards.Tom

Interested in wireless communication? If you have Mathcad 14 or 15 installed, you can download a free copy of my interactive e-book Mobile Channel Characteristics. I’ve been selling it for ten years or so from my Shady Island Press website, but the demise of Mathcad 15 in a few years changed my mind. It would be better to get more copies out and working for a few years, and the best way to do that is a giveaway.Mobile Channel Characteristics is the first, and so far the only, interactive text in wireless communications. Because it is written in Mathcad, it is a live document – try different parameter values, and the equations, tables and graphs recalculate as you watch. You can use its models, analyses, techniques and programs on the job or in your thesis to speed up your work. This book-length reference resides as a Mathcad handbook on your hard drive, just a mouse-click away.Its scope runs from wireless propagation models, to multiantenna (MIMO) transmission, to simulation techniques

Hi, pretty new to Mathcad here - can anyone help with the attached file? in the first solve block, in one of the equations, it says that the units are incompatible - but all the units are in kN, so it should work?Thanks, Michael

I'm working on a heat exchanger analysis problem and was going to use a Given/Find Solve Block to solve a system of equations. There are two heat exchangers in series. Near the top of my mathcad sheet I input the given values for the hot inlet fluid temperature and cold inlet fluid temperature, the physical properties, and mass flow rates. I then list my initial guesses and create the Given/Find block but get an error when using the Find function. Any hints/tips/tricks/concerns?Thanks!

I am trying to solve for TP57, and in Mathcad 15, I select TP57, select symbolic, variable, solve and get the below result, which seems reasonable.I now have MathCAD prime 3, which does produce a nicer looking document, but what is happening here? .. why is the result so drastically different ?is there anything I can do, besides reverting to old MathCAD15 to solve a symbolically?thanksKasper

HiUnsure where to go with this now. I am modelling a system where the diameters of the pipes are different and have 13 equations with 13 unknownsI am modifying an example from a textbook to suit my requirements. (Cengel and Cimbala's Fluid Mechanics Fundamentals and Applications 2nd ed. Page 375) but It's been a while since I have used MathCAD and I'm not an expert in getting it to work. Any help is appreciated.

Hello I write to want to know about my question.I have a problem. you can know to a picture on upper.I read error massage and I knew why error is generated.error is said that it is not possible to divide 'zero'.Could I slove following error? I attached my files.Thank you for reading my question

While I try to get the 30 days try license for MathCAD Prime 3.0, I get the following information after input my account information and press OK. (Account is correct).Do anybody know what the problem is?I think it should be some safety problem of the internet of my company.As the time when I try to use another try version SW, e.g. IAR., I can not access the server.Is there any other way to active my MathCAD? like offline way to get the license.Thank you in advanced!

Could you graph this eq. ? Always says undefined variable

In mathCAD it was possible to create 3D scatter Graphs, I have looked at the Help files in Prime 3.0 and it would suggest it is possible, but i cannot see how its done?Thanks

What is Mesh in the name of the function CreateMesh?Thanks, Val

My friend just bought, on some website, a copy of the "full version" of Mathcad15.After he installs it, he runs some MC1 registration .exe file. The result is that he can run the software perfectly. But when you click on help/about, it shows the version number and everything, and has a name in the "licened to" field, but has a completely blank "product code" field. So, this is some cracked/hacked version I assume? It seems that it should be able to be installed on any machine as often as one would like? No, I will not give any more info on how to get the software. Even though I am not happy with what PTC has done with MC, I am not going to facilitate the stealing of intellectual property. I am just curious if my interpretation of this is correct. Thanks.

I've got a worksheet with an issue I don't understand. I have defined a set of sample indices using "i:=0..Nx-1" then build a spreadsheet using vectors with those indices. I wanted to see the array values when Nx=4 so I set the value and all was ok. When I go to remove the detail ... the [0,1,2,3] display that is ... the rest of the worksheet fails with a message "The value must be a scalar or a matrix". I know I'm being a bit vague but I don't really know how to better explain it so I have attached both good and bad versions of the file.Any help would be appreciatedThanks,Paul

Can I use VBA script to delete xlsx files from inside Mathcad?

Hi,I have two different files in which I have the same function defined. For this function, I want to perform a "minimize" in order to find out its minimum across a certina interval of the variables that make up the function. I would have expected the guess values to have no effect on the rezult of the minimize, but apparently they do have (I get different results from applying "minimize" depending on the guess values I write. Does anybody know whty this happens? Below you may find a screenshot of the two different mathcad files, side by side. I have also attached the files themselves.Thank you and best regards,Cristian

When I create an Analysis from the Analysis tab in Creo Parametric (no "Behavioral Modeler"), the only "type" option available is Prime Analysis. From the Prime Analysis dialogue, I can initiate or load a MathCAD Express Prime 3.0 file. I gather from my reading that in order to pass data between MathCAD and Creo, I need to assign a region tag to the math region in MathCAD. I have read that this is done by right-clicking on the region to bring up the Properties dialogue where the tag can be assigned. Unfortunately, when I right click on a math region in MathCAD Express, there is either no response or just a simple cut/copy/delete menu with no properties item. I can find no alternative for properties or region tags in MathCAD Express Prime. Am I correct in concluding that I'm up the creek without a paddle, or have I overlooked something?

Hi all, I need to divide different imported 2D shapes/curves into triangles having (almost) equal sides. Is it possible in Mathcad?I've found that there are many triangulation functions in MATLAB like trimesh:http://www.mathworks.com/help/matlab/triangulation-representation.htmlbut I'd like to use the results in Creo 2.(I'm not a MathCad or MATLAB user -so far-, just looking for possibilites and solutions.)

Hi, Any one can help me to correct my mathermatical expression using MATH CAD prime 3.0. I attached the spreadsheet and I need to get an answer for the element in Array if the element is Compact, semi or slender.Please resend to me the file with your correct mathematical formulas.

I am sorry, because I guess that my question is either very trivial (and I missed it), or without positive answer.I need to change in a Mathcad (v.11 still, but I tried also with v.15) a matrix dimension from 3 to 2. I have several equations, with "identity(3)" function, that needs to be corrected accordingly. I thought that the replace command would suffice to make a global change. Yet there is no way that Mathcad finds (both regions selected) the terms "identity(3)" in my worksheet, even if they are there. The culprit seems the bracket character. Is there a way to make the find/replace command work? Thanks.

Hi All,I am trying to set up the following definite Integral in MathCad as a function of wt, not just t, how would I do that.eg (1/2pi) Int 0 to 3 sin(wt-0.361) dwt.Thanks in advance.Vijay
