IAPWS-IF97 formulation - http://www.iapws.org/relguide/IF97-Rev.pdfIf you do a reference on the link http://twt.mpei.ac.ru/TTHB/NPP/mathcad-functions/H2O.xmcdz in your work-sheet.You can find in attach some same functions for Mathcad Prime too.Some functions with properties of water and steam will be visible in the sheet as it is showed on this picture:Prof. Valery Ochkov - a member of the Working Group of The International Association for the Properties of Water and Steam

The following picture shows how to use references in a worksheet.Does anyone have something to add?Pay attention to the verses of the arrows. The arch, can not close on itself.

I have recently found out that I cannot add words to the personal dictionary during spell checking. This happens on two machines both running Mathcad 15 one M045 and the other M040 running under Windows 7.  It turns out that I cannot save custom words because I do not run Mathcad from an account that has administrator privileges on either. Selecting Mathcad and running as administrator does not solve the problem and I suspect that Mathcad is really not being run with administrator privileges because it does not ask for my administrator password. Has anyone else run into this problem?The only solution PTC provided was for me to talk to our IT department, but I seriously doubt they are going to waive their practice of having people operate with a regular account rather than administrator account just to accommodate Mathcad 15. Many of us have access to an administrator account, but I'm disinclined to waive security procedures by regularly running Mathcad under my administrator accou

Hi,I am trying to plot a graph using the following vectors, but I am getting a graph which is different from the expected:What I am getting is below:Where as the one I am expecting is as below:Though, I could able to get this in Mathcad by manipulating the values in the vectors as below, it is still a manipulation of the data!!!. Can someone suggest me where am I doing the mistake?

Hi,I am trying to plot a graph against two different functions (FunctionX on X-axis and FunctionY on Y-axis). I would like to know if a graph can be prepared with the following:1. FunctionX returns a matrix of size 'm x 1' in which each element is again a matrix of size of '2 x n'2. FunctionY also returns a matrix of size 'm x 1' in which each element is again a matrix of size of '2 x n'.Can some suggest me on how to plot this into 2D graph.Results of the Functions are indicated in the image below.Thanks in Advance

Hi,I' ve the following : https://en.wikipedia.org/wiki/Vibrations_of_a_circular_membraneI'm sure that this will also work in Mathcad, but, at the moment, I've no idea how to get this thing runningin polar, cylindrical,, or whatever coordinates, to create the same wikipedia animation.Have you any ideas ?Thanks in advance.

Hello, Everyone.  Need help with creating program function G( ), the above.      Thanks in advance for your time and help.            Regards.

  Hello Everyone.From :And the question is : solve, create program function M_(  ) , the above ?    Thanks in advance for your time and help.         Best Regards.

I am trying to design a part with two variable diameters.  I change the values of the two diameters at the top of the document and a final answer is displayed at the end of the document.  Is there a way to show the final answer near the top of the document so that I may see what the final answer is while still at the top of the document?Thanks in advance.

Sorry to say but its so annoying.I have been digging my head to get the API of mathcad prime the whole day.I could only see discussion about the API and SDK files but not the link of any API so that I can download it and use it in my programming.I am very new to mathcad and without API I am not able to do anything.If anyone had a link or document then I humbly request you to share me.I would be very grateful.* I am using Mathcad 30days trial version, should I have to buy Mathcad in order to use its API?Regards,Prarthana

Hi Community!It would be very useful to have the entire Eurocode 3 (1993-x-x) written in Mathcad. One could from that spreadsheet cut-n-paste formulaes into the calculations one are doing.Does something like this exist? It would be a huge job to write it, but very useful for the world of engineers when available.best regards,Håkon.

I have Creo 3 and mathcad 3.0 but only mathcad works.what can i do ??

Hello, Everyone.The question is : solve, matrix X with matrix equation ?    Thanks in advance for your time and help.          Best Regards.

Hi everyone,I am planning to use Mathcad prime Express in my development calculation after 30 days of my Mathcad prime trail completion.So, I would like to know whether  or not Mathcad prime express supports simple exponential calculation,Sin, Cos function or not and their graph or not?For eg:Regards,Prathana

Hi everyoneI am new to MathCad and want to implement this equation in mathcad. I tried but still errors can any one help me in implementing this problem.  The attachment is my file.Thanks

Hi everyone, i am new in this community, and i hope that someone can help me!I would like to find the lowest temperature in the range of 500-600K which maximizes the production of species B.I solved the 3 ODEs in function of my unknown T. Now i would like to create a vector of temperatures (from 500 to 600 K), and for each of these temperatures calculate the production of B.Is it possible to do this (maybe using a program)? Thank you!

If I write a function as a program in one document is there a way to use it in another document without re writing it?

I have this conditional formulas between satisfactory and fail .  How can I turn text to red color if the condition is "fail". Only the FAIL  text will turn to red color.

Hi all,I've deduced the Cauchy-Riemann DEs from x-y coordinates to polar coordinatesusing Mathcad's symbolic capabilities.Greatings.

Hi all, would anyone help me about one question of the conditional setting of a time domain function? I have two function y1 and y2, whose slew rate can be defined independently. I want to set a condition of y2, by setting "when y2 and y3 meet between t1 and t2, y2 must follow y1".Attached is the worksheet, would anyone teach me how to do it?Thank you!

One, of the many differences, is the one found in the graphic, very evident in the following image:

  HelloWhat is the difference between Prime and Machcad 15, because the function works in 15, but in Prime does not work.And also there is a possibility that Pime read M 15.!greetings

I want to have a bar identifier as bar #1 #2 #3 #4 to #11for each bar, a diameter and area.also for each a type of elastic modulus (if steel, if carbon fiber, if glass fiber, etc.)Yesterday I was told that Mathcad Prime does not offer a drop list box for this. However I was watching youtube and I noticed that using excel can be done. How can I do it and have this information somehow accessible for every calculation I perform like a tool box.for example when I choose #2 bar then I want all these properties to appear in the calculation without having me to do them all over.I would like to do these for large data sets.please advise how. Thank you

I would like to know how to provide proper protection for my complex worksheets before sharing it with external parties.Aiming for the followings:- protection of the hidden areas against opening- time limit of usage using expiry date (hopefully not linked to system time of the particular computer)- runs only if hardware dongle is present (therefore copies and the distribution of software is limited)Regards,Andras K.

What is wrong with my variable ratio please help me.  I attached the Prime 3.1   file for you to correct my mistake   . I would like to make a graph like what I attached below. I appreciate your full support in advance  . Thank you.
