Where di I find the file to convert old MathCAD files?

Is there a function for natural trig outputand not radians ie sine(45)=.70711?

Hi all, Thanks is advance.I am making a graph for moments vs load radius..My Load radius start at 10.3m and hence the graph lines also start at that point (the vertical line in the document). But I want those lines to start from zero ( I mean y axis). How can I do so?I am making these plots against LoadRadius, Rw which has three values in a matirx but my other variables just has one constant value. So how can I put these constant value against three load radius, which will utimately produce a straight horizontal line. Here in the graph I have used a technique writing Friction= C*Rw/Rw which is not smart way I think.I am using mathcad prime 3.0Best RegardsJahangir Hossain

Does the information given by the system mean that mathcad cannot handle this kind of parabolic equation?

One of our engineers mentioned that text boxes always change size when re-opening a file. So if his file contained a text box with 3 lines of text when he re-opens the file the text box has changed to 6 lines of text and the text box is smaller. He said this has been on ongoing issue since time began. Can someone shed some light on this?

Document interaction in Prime is so awkward and time-consuming that it makes users mutter, "This is garbage," (or words to that effect) and swear never to to use Prime again. That can't be good for marketing or sales. These simple actions - moving around in a document, cutting/copying and pasting regions from one place to another, expanding and collapsing areas, editing equations and programs, and so on - are performed constantly when developing a worksheet. Making them easy to do should be a design priority. Yet, in that area, Prime is perhaps the worst of all significant Windows programs.It's serious. Although lack of some advanced features may disappoint users, document interaction problems actually repel them. Fixing those problems should be a priority, if only to keep PTC's user base.Some are listed below in the hope that they will be fixed. Anyone care to add to the list?* Prime is slow and unresponsive. The delayed imaging of characters when typing in a text box is merely irrita

I got error in left of the picture. so I did tracking. and I knew first error by using traking. But I can't understand the reason that error is generated. error is said that you can't divide '0'.

I tried to finish following process. But I continually got error when I coded.So I uploaded process steps. and I also attached my files.I am early step about studying 'mathcad'. So I want you to help.

How do i create a surface/mesh in mathcad?and will it be possible to take the surface/mesh to Creo, and vice versa?

Hello.I just got the Mathcad15 from my school with the license code for the Student-Edition.I installed everything and it also said that it was installed correctly and it is all finished.Now I wanted to open it and it gives me following message:The first line translated means that my requested license has a failure.The last ones mean that i can press "Yes" to restart the license-setup-assistent and try open Mathcad again after that. That didn´t help.Can somebody please help me?Sorry for my bad english, I´m from Austria 😉Kind regards

Hi there,Not sure if I have an incorrect implementation/setup or if it's some kind of bug...If I perform the following in Mathcad 2001i, it works instantly:If I perform the same in Mathcad 15 it will not solve and I eventually I get the message "Condition contains Otherwise in subexpression".I have attached the files I have been using for your perusal.

Please could the Mathcad team in PTC compile the next 040 release of Mathcad 15 as 64bit as well as 32 bit. For those of us who still love Mathcad 15 and could do with the extra memory it would be a big help without any great effort from PTC.Andrew

Hi,Pretty new user to mathcad, was introduced to it as a way of formatting equations for validation and checking purposes.Please see the attached mathcad page for a page of calcs that I'm struggling with. Its calculations for a variable section beam, done as part of an ANSYS validation exerciseCalculations are on deflection of a beam per unit of force applied.Hopefully my equations are understandable, I've included references for relevant dimensions and theory.My question:When writing functions f(z), how do you define the units of the z variable?Is there a simple way of doing this that I have missed?I've set up calculations for Moment of inertia: I(z), using the height of the section: (z) as a variable.The issue that I seem to be having: z is dimensionless, but I want units of this variable to be mmNot having a unit assigned to the z variable causes several issues:I later use the unit load method to calculate deflection (per unit force: mm/N) This involves a definite integral in terms

I have been playing around using different methods to solve a polynomial equation and need the help of one of the 'symbolic guru's on here.I have managed to solve the equation and evaluated numerically, but have the following queries:Can I force the symbolic result to return only real valuesIs 'float' required to evaluate the symbolic expression numericallyIs there a more elegant way to solve this equation.Thanks,Mike

I'm using code off of a project partner where he laid out a find/given function using the programming feature. In most instances it works, however when I change a variable value or add a variable to the equation, it goes "undefined" and will no longer give me an answer. This seems work well when we did the original calculation sheet, however, when I go and try to make revisions to it there are problems that always occur.Even when I just copy and paste the parts to another worksheet it stops working.I didn't want to redo his entire worksheet using another method to find the answers. Does anyone know why I would keep having problems with this method? Is there some syntax that is very discrete that I'm missing? If not solving through this method, do you have a recommendation?Thanks,Nick

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.
