I have tried several times to have the link emailed to me to download the free version of Mathcad but I am not receiving the email. I have checked the spam folders and there is no email.
Dears, I´m using with great success the Coolprop wrapper, but one challenging task is to form the "mixture" string. Air for instance must be written as: "O2[0.21]&N2[0.79]" When working with complex mixtures, like up to 10 components, my idea was to use a table and extract a "concat" function from the table. All good doing it the hard way:(...)Problem: if I add or remove one of the 10 components from the table, maybe for a simpler composition, then the formula for "mixture" would fail. Solution: maybe write a program? But don´t even know how to start. Any help would be great. Best regards, Fred.
I attached a simple example (clark transformation). Assume that I do not know the relationship between Uabc ,Ualpha and Ubeta. How can I derive the final transformation from the known equations? Thanks. The file was writen in Prime 8.
I am using a step function to define the first two values which are slightly different than the subsequent values and was able to do this in MathCAD v15, but I have just moved to Prime 8 and the function no longer works. The except from MathCAD v15 is shown below. How do I do the same sort of iterative function in Prime 8?
Hi all,I am facing the following problem:I am defining a function with four variables, three of them jsut a number, and one is defined as a series or sequence. (sorry if incorrect)I would like to obtain the maximum of the resulting sequence after the function evaluates the variables, but it looks that this is not exactly a matrix, since the max function is not working correctly:thanks all! PD: I have seen some solutions but I am unable to open those files. @MarkArmstrong https://community.ptc.com/t5/Mathcad/Create-a-vector-from-the-result-of-a-function/m-p/191688/highlight/true#M75105
Good morning, guys.I've struggling to complete the installation of the software of yours.It always ends up with an error, no matter what.The error message appears after completing 1% of the installation as follow:"Some applications failed or cancelled. Click information icon of failed application for details"Although, when I click it for further details, it just states the obvious ... that the "installion has failed " and it has created a log about the error , this which I could never find.Looking forward for a feedback for support.It's kinda frustating.And I'm in really need of the software right now.
I was having problems with the MCDM converter and ran through a bunch of troubleshooting. I finally got to the step of uninstall and reinstall. Sadly, I have not been able to reinstall, getting 1% error. I use this software often for school and I have a student license. I am having trouble downloading the installation file also but got it on another computer. Anyway I am going to take some snips of my screens and hopefully someone can tell me something to check to fix this. I am getting stressed and desperate as I must have this software to complete my classwork. next nextnotice this closeup of above nextNotice again still showing Zero MB The installer then sits here and does not download and after about 20 minutes fails and trying to restart it fails. I have been trying to fix this for hours for the last three days and I am needing help soon. I am hoping somone knows something else I can do or try, I
It is necessary to express the power of the power plant in decibels.I go online and find out that bel is the decimal logarithm of the ratio of two physical quantities, the second of which (the denominator of the fraction) is called a certain base. In the same place on the Internet you can find the corresponding formula for the calculation.Here's how such a calculation might look like in Mathcad 15 with the help of tools for separating variable and function names into styles using different font colors (black, green, blue and white - invisible).If one watt is taken as the base, then the power of the largest Russian thermal power plant, Surgutskaya GRES-2, will be 96.812 decibels (see please the picture and the attach). We solve the inverse problem: given the power in decibels, it is necessary to calculate the power in the usual watts. Question. Why are decibels called decibels and not decabels? After all, if we multiply the logarithm by ten, and not by one tenth. See please als
Hi I'm trying to solve an issue where I want the if function to work, when one of the variables in some cases could be undefined. Is this possible, or have some work around? I'm using Prime 9.
I m trying to calculate the reaction influence line for a simple indeterminate beam problem.I built up functions for fixed end moment and slope deflection equations. Now I m trying to calculate rotations at the end supports of the beam, I m getting error because the slope deflections equations are conditional expressions. I m expecting set of end moments when the load is placed on the particular element. How can I achieve this ?
I want to have the plot values on scale directly and not modify the scale within plot is it possible in 15?
I can't use the 30 day trial version of mathcad prime 9 and I'm new to the community. ----------------Translated below text to English using google translate. Done by Community Moderation.

My 3D plots have started appearing like this:When I drag the plot area, the problem disappears:But as soon as I let it go, the weird pattern reappears. I thought it might be a problem with the mesh frequency pairing with the pixel spacing on my display, but resizing does nothing, and, in fact, the problem appears as soon as I open a new 3D plot area. Anyone encountered this? More pertinent question: does anyone have a solution?Working in Prime 8.0.0.0 Thanks for any hints.Richard
Hi I want to extract a given value from a table based upon two variables. For exampel, by selecting the variables "A" and "b" I want the extracted value (output) to be "5". Is this possible to do? Thanks in advance.
Computer was replaced need to download the installation files for Mathcad 15 to reinstall on new computer.
Has anyone figured out the format to use the TAG tool when doing an internal link. The instructions seem to say the TAG is #xxx. But when I link to it a text box I don't get it to transfer to the TAG. Yes i am using [ctrl-click] .In Mathcad 15 it was a useful tool to move around a multi-page worksheet.
Hello, I have recently installed Prime 9.0 on my professional DELL laptop running Win 10 but when I launch the program, nothing happens, no pop-up screen nothing: the mouse cursor does its usual circles for a few seconds and then vanishes. I had to run the installation under a dedicated admin account but then back to my account, I can't start Prime even I run it again with admin priviledges. It actually happened recently with an install I did with 7.0 and I could no longer launch it in the end while I could use it for a year or so. It is what motivated the migration to 9.0 but the problem remains. I've checked for a log file in the PTC folder but could not see one. Also checked the Symantec log files, nothing reported. If you could point me to some solutions I could explore, I would appreciate. Thank you. Christophe--
My company, Aerolab LLC, purchased a floating network license for Mathcad. PTC support installed Mathcad Prime 9 remotely for us. He gave us no information as to where the license is located or how to access it. I am trying to Install and activate another copy of Mathcad to use this floating network license. Please help.
I have purchased the student account. However, I have not received my product code.When do i receive this? Should this not be automatic for a digital product?
Hello,In the solution to my recently asked question "programming a recursion" it was noted that MC has problems with the accuracy of long-number arithmetic. As a test in derive I have successfully solved the following task: To determine a power of two, i.e. 2^n for natural n, which begins with the decadic digit sequence 2023. I am interested in an MC-compatible search algorithm.If you are interested, I would be happy to provide my derive solution as an attached text file. Which text format is desired here in this forum? Kind regards, Alfred Flasshaar
Hello Experts, What does Argument outside of solution interval error means and how to overcome this one? Also within Odesolve when there is no variable used for range variable still the plot can be plotted using the equation function. How to find out what does k subsides in this worksheet
I'm trying to buy Mathcad for use in the classes I teach. PTC seems to have handed off their online sales to a company called Digital River, but the web site also directs me to a sales rep who works for a company called EAC Product Development Solutions. She offered to sell me a 1 year license for $295 when the online price is $56. I don't understand what's going on. Is this the same version? I just got off the phone with the rep at EAC (who was professional and helpful, BTW) and she couldn't explain what PTC was doing, but is trying to get me an answer. She did say that she gets lots of complaints about how hard it is to deal with PTC. Ugh. Can anyone in the community enlighten me? It seems like PTC has decided to outsource their sales, but has sent it to two different companies who don't talk to each other and have different pricing. Can this be right? I have to be missing something. Mark
We have an older perpetual version of Mathcad that we need to move from an old computer to a new one. I cannot find anywhere in my account profile to change the MAC address so that the new computer will be recognized. Does anyone know how to do that?
Here, the students and I saw an animation on the site Pendulum - Wikipedia showing the position of the velocity and acceleration vectors of the pendulum.We wanted to reproduce the acceleration animation in Mathcad - see the animation and the file in the attachment.But our animation is different from Wikipedia's animation - we have a maximum acceleration, and there is a minimum. Where is the error - with us or in Wikipedia?
