Is it possible to open or import Mathcad Express 4.0 file in Mathcad 3.0 Prime (full academic license)?

I´ve plot a stem trace graph. and dont know why 2 points with the same values (in the y axis) dont be at the same height.Here a screen shot.Hope u guys can help me.See u later.

Hello again friends,I have what is hopefully a simple headache in integration.I am looking at the below and attached.In yellow is the integral I am trying to work out manually as I need to be able to do this in a manual way. I have tried a 'nifty' short cut in red but this is way off.Then I have tried integrating without the upper and lower limits of the integral by rearranging, expanding the brackets, then integrating. Then replacing z for -T and resolving. Although this gives me an answer with a extra 5 in the numerator?Any ideas where I am going wrong?A

In MathCAD 14 I am attempting to find the maximum absolute value in a vector that contains positive and negative numbers. With only positve numbers in the vector this works to determine the maximum value: max(vector)=With positive and negative values I have tried putting the vector in absolute value bars within the max function like this:max([vector])=but the answer is strange and is larger than the aboslute value of any of the entrys in the vector (maybe it's finding the determinant?).How can a command be written to find the maximum of all the absolute values in a vector?

Hi,   I have a question to solve a DAE-system of a chemical reactor. In the picture you can see a minimal example. Its a simple reaction A to B with a first order kinetic multiplicated with an arhenius equation and an empirical pressure factor. To solve the DGL system, I have to predict the pressure p, wich depends on the mol fractions and temperatur. So this is my algebraic equation. This equation is combined with a DGL of the energy balance and two mass balnce. How can I solve such a system? With the example of mathcad, i can't solve this. Is there a simple way or standard method? I want to solve the system with RADAU so i have to built the vector function D. How i have to implement the pressure equation?   Thanks for your help

How to open MathCad Express 4.0 file in MathCad 3.0 Prime (full academic license) ?

To simplify a project where multiple steel frames are being designed I've incorporated the use of "include worksheet" in MathCAD prime 3.1All the worksheets include a worksheet that has basic quantities calculated, like a parent - multiple child relationship. I've now tried to have one of the child worksheets include another child worksheet and I get the errors in the attached image. Reloading the worksheet has eliminated the green error but the red error persists. The included worksheet has no errors. Are there any limitations to including worksheets that would not allow this include to work?

Hi,May I ask some help to improve my spreadsheet that will satisfy all conditions. Sometime the  utilization  of the bending moment is greater than 1 from  my initial profile selections. I need to have a profile that are adequate  in the design from the selections of the profile I attached .  Here is the Mathcad file  and read Exel file for your reference . Thank you..

See please the Mathcad Prime 3.1 or pdf in attach.

‌Is there a quick way to insert a variable into a equasion, which you already used before?(simulare to C). It is quite the effort with indices!

Hey guys,is it possible to transfer the yellow marked equation to MS Excel as a direct function?I dont know what to do with lambertW.ThxStefan

Hello dear community !   Results of sign function in the attached worksheet are quite tricky. When calculations for a root under the argument of sign function are done only with integers the result is always like expected, i. e. 0 ? Why this behavior ?  Binary representation of numbers in numeric engine of Mcd...? I'd have wished a more consistent implementation of sign function, for example in agreement with the precision given by TOL or of the symbolic calculus (like in Mcd2001), or without differences between integers and rational (real) numbers... Same behavior in Mcd Prime ? I've used this function for roots testing in a program and I was surprised to discover that thus I missed some, like in the case of p30f in attached, where the output of sign is not 0 (zero), as expected for a root of the polynomial in sign argument. In order to make sign function work evenly in all cases I added round built-in function, the version with two arguments, the second being -log(TOL). Are

Hi Every oneIn MathCAD 15 I was able to use vlookup referred to the tables inside the worksheetbecause any table has a specific name but because in Mathcad Prime there is no name related to table I can not do that at allI do know How to can do the the same in Prime without using excelI do not like using excel entire worksheet because every time you have to double click on it & going to another program in fact , it is also take unnecessarily time,It would be your kind if you find any solution in this regards except using Matrix

Hello,could someone advise how to interconnect external data with spline points?I generate coordinates in my external program .I use matlab now but can write code in anything. I want to drive spline points with this coordinates. I know I can save the coordinates to file and load in creo during editing the spline but this is not what I need. I would like at least the creo to read the file automatically during regeneration. Another possibility is to create program in mathcad and exchange data with parameters. There is problem the number of points change. Is it possible to use the spline from mathcad as geometry in creo?Are there any other ideas?(in Creo 3)Thanks, best regardsmichal

Ьщку Hello, World! See my 1-st Prime Animation! Video Link : 7863

How do you frame the header and footer in Mathcad prime? In Mathcad 15 there is a box that you can check off. I don't find anything like that in Prime.

Hi guys,I have a quastion. I give you an minimal example. I want to solve a ODE-system with the Radau-Solver. Therefore I need to build the derivate B to component X_2. In the picture you can see, that i can write only X. How can i build this derivate? I know the derivate ist X_1+X_2, but in my real problem i have a big equation-system with many function in another function. So i need a practical solution like  d/dX_2(X_1+X_0*X_2). Can someone help me?

I have two sheets - Mathcad 15 and Prime 3.1.I hope both sheet is equal. But there is an error in the Mathcad 15 sheet.It is a bug in Mathcad 15 or an error in my Mathcad 15 sheet?If I convert the Mathcad 15 sheet into Prime - all is OK!Help please - I am myself going to bugs...

Hello, I have a Problem updating my current version of mathcad. It isn't possible for me to download the newest version. Can you tell me the steps which I habe to do? Thanks for your help.

Hi,I am new to Mathcad, and I am using Mathcad prime 3.0. I need to plot the phase of my transfer function and am lost where to start. Here is what I have. Any help would be greatly appreciated! Thanks.

I am trying to solve a problem of heat transfer in cylindrical coordinates with a boundary condition of convection in the surface. When I write the differential equation and conditions in Mathcad 14, all in prime notation, odesolve cannot find the solution. An error message appears informing that there are too few initial conditions.  As I am dealing with a second order ODE and I am providing the required two boundary conditions , I don´t consider this is the problem.

Хочу рассказать одну интересную историю в канун Дня Победы.Sorry, for Google translator! May be somebody correct it! I want to tell you an interesting story on the eve of Victory Day. Была у меня первая книга про Mathcad с одним соавтором. На обложку мы поместили распечатанный на принтере (они назывались АЦПУ - алфовитно-цифровое печатающее устройство) крестиками и ноликами портрет Моны Лизы. Тогда (1990 г.) это было еще свежо и в диковинку.I had my first book about Mathcad ( the title "From micro calculator to PC" - Mathcad for DOS) with one co-author. On the cover we put printed on the printer with crosses and toes a portrait of Mona Lisa. Then (1990) it was still fresh and in wonder.Мой соавтор (а он прошел всю войну, был офицером-связистом) принес только что отпечатанную книгу домой и показал жене. Жена спросила: "Кто это!?". Он ответил: "Как кто - это Мона Лиза сиречь Джоконда!". Жена грозно воскликнула: "Какая такая Джоконда!? Это Райка - твоя радистка, с которой ты любовь на фро
