Mathcad

I dont need all the worksheets in the expensive Vol.1 Worksheets, I just want to see the Custom functions such as matrices to c-code. Are  any of these free anywhere or can the custom functions package be purchased separately?

This PDF document is a study on climate modeling.   It uses the energy balance principle for creating the the single layer model. The primary objective of this study to gain skills and understanding in climate modeling which comes from 'Energy Systems Engineering: Evaluation and Implementation' by Vanek, Albright and Angenent.   Some Prime-Mathcad users may be interested in this topic and taking it further to apply the features in Prime-Mathcad to create models for multilayer climate modeling.   Primary target of interest: 1. Senior students in engineering and science. 2. Practicing engineers. 3. Others new in the field related to Climate, Green, and Renewable Energy.   Textbook Resources: 1). Energy Systems Engineering (Vanek Albright & Angenent)-Primary. 2). Other references indicated in notes.   Apologies for any errors and omissions.

Hi All,   These may be some stupid questions, but new to this environment from an excel background...   I have a number of questions which pertain primarily to how to use data within list / combo-box etc. to be able to extract a number of standard parameters associated with, snippet's below & file attached    

Why I have got this strange solution? See please the picture and the Mathcad 15 file in attach.

Hello. We have server with 2 floating licensesI try to create xml file for silent installation,but I have two questions1. I as administrator created xml file, after first installation (mathcad.p.xml)I have edited xml but one line <PROPERTY name="[APPLICATIONDATA]">C:\Users\Admin\AppData\Roaming</PROPERTY>I dont understand what have to be instead of Admin, I think CurrentUSER but how it will look like?<PROPERTY name="[APPLICATIONDATA]">%Currentuser%\AppData\Roaming</PROPERTY>or something else?2. Second question is:Could you help me to edit this line<MSIARGUMENT>LICENSEPATHFORM="ServerAndPort" LICENSEPATH="7788@localhost"</MSIARGUMENT>Our server fpr example Server port 7788 how will be right:<MSIARGUMENT>LICENSEPATHFORM="Server:7788 or Server@7788" LICENSEPATH="7788@localhost"</MSIARGUMENT>Thank you for your answers.

Hi,I have a simple Problem however I'm searching since nearly one hour for the solution. I'm looking to calculate the mean in an Array. I Have R=(x1, x2, ....) and i want to calculate the mean of every value in the Array like Rm1=(x1+x2)/2 Rm2=(x2+x3)/2 ... and so on. How does it work im Mathcad? The normal Matrix Indicies with i and i+1 doesn't work.I also attached a short Version of the Mathcad file, especially to focus on this Problem. Thanks for helping 😊

Hi,   I am trying to solve an equation with overall two constrains. However, the Find(var1) function gives an error. I am attaching a Mathcad 15 file for the refrence. Any leads would be much appreciated.   Many thanks S

I'm trying to take the derivative of a function with respect to t but it shows as 0 when it is not. could you please help? Thanks Prashanth Rajendran  

Hi, im totally newbie. I have 2 problems and i dont know hot to solve it 😕   Any ideas ?

Good day to all users! During creating of the calculation in mathcad 15 I faced a error in cycle -"array index is invalid for this array". You can see this at the end of file. I have correct cycle without array, but i can't do it with array. The number of this array elements is small - 146. What is the error of this calculation?   thanks in advance!

Hello everyone,is there a very expert who would like to complete the attached work?It seems to me to be quite simple.Thank you very much for who will try to do it.Greetings  on the sphere).

Hi,   I have X & Y defined as two matrix variables, which I can do a linear interpolation between them...   How can I perform the same interpolation if I have X & Y in a combined matrix, ?I am attaching the Mathcad file  

Hi, Is there anyway to plot a line in 3D graph tool? It seems like intrpolation doesn't work in 3D if all the points lie in a line. A patchy solution is to plot in a scatter point, but it indeed looks ugly. I would really appriciate if someone has any clever solution. I am attaching a Matchad 15 file for the refrence.     Many thanks S

I have programmed a loop calculation to obtain the minimum value of the (Pf) variable. This variable is a function of three independent parameters (i, k, and θ). To do these things I have issues as attached. Your help is deeply appreciated. Thank you.  

Hola, al abrir un documento de mathcad prime 7 en el prime 6 me aparece el siguiente mensaje y tampoco sé como hacer compatible los documentos del prime 7 al prime 6. Si alguien sabe arreglarlo o hacerlos compatibles agradecería su ayuda.  

Hi MathCAD community!  I am working with a customer that has not been able to open an existing file which is stored on his server, as it will only open in READ ONLY format.  So, he has been copying the file to his local machine doing my work, saving locally, then copying the file from his local machine back to his server.    Any ideas?   Thank you all!

Hello,   "odesolve" works with A*y''(t) + B*y'(t) + 3*y(t) / (y(t)² + 1) = 0 but it doesn't work with the substitution termC(y(t)) = 3*y(t) / (y(t)² + 1)A*y''(t) + B*y'(t) + C(y(t)) = 0 I tried in several ways to define C, e.g.  C:= 3*y(t) / (y(t)² + 1); C(t, y) = 3*y(t) / (y(t)² + 1) ... etc, but in vain!I am attaching my file to this post and would appreciate your help very much !  Thank you in advance, Peter      

Greetings! My license has expired, now I´m trying to change my account because I need it for school, but I don´t now how to do it. Can someone help me please? I tried to expand my license but that didn`t work, that`s why I´m trying to change the account.

Hello, Today I made my work for Hydrodynamics. It's about this Equation:   Every Variable except h2 is calculated before and so I'm looking for h2. I have no idea how this could work, the solve function does not work.Pleas can you help me out with this Problem?Thenks a lot 😎

First of all, I extend my gratitude to all of you! @Werner_E@LucMeekes@ttokoro@Fred_Kohlhepp@terryhendicott@ValeryOchkov You people are really fantastic. I am a recent user of Mathcad and now in the learning phase. I have never seen any community being run by a handful of people. I searched, and searched a lot on different topics in Mathcad and always find satisfying answers. Apart from this, I realize that the answer was always by one of these angelic personalities. I have visited, posted in different communities but I would say that this community is above all. It has a very excellent response time. It feels these are "just post your question I can't wait more!" type people in this community always welcoming to solve the miseries of people. The second best thing is that you people are like the real guru of Mathcad. Never seen a reply "I don't understand" so far. That's amazing!   I have just one request. A three-minute video can explain something better than a thousand-word answ

Prime 7 has automatic calculation like Real Mathcad? If not, why?  

Hello everyone, I want to make a curve plot but having issues as in the attached image and Mathcad worksheet, appreciate if anyone helps.

Hello Guys!   I want to analyse my circuit, using laplace transformation.   Step 1) First I have to generate a triangle waveform. I have all informations given like peak-value, duty cycles, frequency, and so on. I could obtain a triangle waveform by defining sections with the if-equation, according to the post from Werner: https://community.ptc.com/t5/PTC-Mathcad/Plots-for-Conditional-Function/td-p/124048   My first idea was to multiply a sawtooth function with a rect function, but nevermind. I keep the solution from Werner I guess if the following Step 2) will work...   Another approach would be a fourier row to obtain the triangle shape. Maybe you have some older work / examples here for me?   Step 2-4) I want to make a Laplace Transformation from the triangle waveform, means: i(t) -> I(s)   --> is it posible with my function from Step 1) to do a laplace transformation, or do I have to go the approach with fourier rows?   (Step 3) Vout(s)=I(s)

I have an excel file that contains material property data.  I have several sheets in the file; Aluminum, Titanium, Steel etc.   Each sheet contains data for several alloys, one for each row.   In Mathcad Prime 7, I would like to be able to select a material of choice.  I thought of having a combi box that selected what type (Aluminum, Steel etc), then a 2nd combi box that would show a list of materials based on the type and allow the user to select the material from that list.  Once the user selects, I would like to load the material property data for that specific material.  It is important that once the Mathcad file is saved and closed that it retains the selections that were in the combi box.   Is this possible?  Maybe there is a better way...

Hello to the whole community !!!What to do to get the correct answer? Thank you in advance, who will answer.
