Hello everyone,in the attached file, i am not understanding how the program r2 iterates.Could someone please explain why I am receiving the same options multiple times in the output.Attached Mathcad 10 sheet. 

Hi I would like to solve a differential equation for a set of variables. I hope I have clarified my problem in the attached file (prime 7), otherwise just let me know.   All help is very appreciated! Thank you 🙂

I have 15 executable MathCad Prime 8 calculations that I’d like to run from a Windows Command batch file. How do I do this?

HiIs there a function in MathCad Prime (latest version or 9) where you can put a form field in formulas? I'll give an example:Variable = [form field] mm This is because I've noticed that when I make spreadsheets and make different calculation formulas, e.g.: k = x mm * y mmso often someone accidentally removes the units, and it then completely messes up all the calculations. So I'm looking for something similar to Excel, where each value is in its own cell. If there was a form field in the formula, other parts wouldn't be easily editable.

I need a license file update for MathCad 14 M020.

Need MathCad 14 m020 license file for re-installation after computer crash and Win11 reinstallation.

Hi,I purchased a MathCAD license for MathCAD prime.I have an account, a customer number, a sales order number and a site number.In addition, when I download a summary of my license, I get a zip file with a customer number and a 13 character number.But when I need to install the license, I need to register a 14 character code + 4 +4 code.Where or how can I get the "product code" or a license file?Regards 

I have an iteration in a calculation that requires I select “Calculate” repeatedly until two numbers are relatively equal. Is there a way to automate this iteration so that I only need to select “Calculate” once?

I ran the same program in mathcad14 and mathcad prime10 through a converter, and it was slower in prime. Below is a program that seems to take a long time to calculate. I also got the following information: "The most efficient way to use computer memory when using matrices is to pre-allocate the matrix. To do this, assign 0 to the last element of the matrix. This ensures that there is enough memory for the remaining elements of the matrix. If you dynamically allocate a matrix by filling in the elements of the matrix from the smallest subscript to the largest subscript, it will take longer to calculate and the worksheet will calculate slower." But I don't know how to improve it.

Hello, I would like to get some help from you in order to be able to calculate the output voltage of an integrator OPAMP considering also its saturation.As it could be seen in my example that I attached, the output voltage will start decreasing from 0V with a negative slope, proportional with time. The negative supply of the OPAMP is -6V, so I would like to know if you could tell me please how can I upgrade my calculation formula with some logic in order to check if the output voltage is still less than -6V, then it should be calculated according to the formula, otherwise it means that the OPAMP is saturated and the output is staying at -6V? Thank you in advance! 

Hi everyone,I’m new to Mathcad Prime and have no prior experience with it. I’m currently looking for teaching materials or tutorials related to power supply design using Mathcad Prime.Could anyone share resources, examples, or websites to help me get started? I’d also appreciate suggestions on where to begin learning the basics of Mathcad Prime.Thank you so much for your help!

Hi there , I'm trying to find the q values that correspond to levels values . Knowing that q was measured from z which include the levels values as well . like the example Thanks in advance 

MathCAD Prime 7.0 is where my company is still stuck at, but it still has the very frustrating limitation/bug of not accepting decimal numbers without putting a leading zero before the decimal. It allows you to do this when calculating a number, but not when using units. Has this been fixed in subsequent versions?  It is frustrating not only from the standpoint that I never put leading zeros before a decimal, and never have, never do on any other program/software, and it's not a problem at any other time on any other software package I use (including MathCAD Prime 7.0) UNTIL I try to use units in the calculation. I have hundreds of worksheets where I have not used leading zeros and it used to calculate everything just fine, even with the use of units.

I'm using MathCAD Prime 10.0.1.0 and having difficulty having a function complete a different formula depending on if a previous variable is either "Yes", "No" or "Blank".  The loop is meant to repeatedly calculate "b" and then determine if "b" is either a "yes" or "no", I added a blank option to allow the calculation to be skipped in a larger document if that section is left blank. However, it is just always registering the "b" variable as "blank".The answers need to be provided in a matrices format.  

I need to open my Mathcad 15 files. I can't do it with Mathcad Express. Is there a way to work with existing Masthcad 15 documents.

Hi  I want to plot numbers from a table along with a function. But - if I select for example Row 2 and Class C, I want NaN to appear, i.e no value at all in the plot. Is it possible to incorporate NaN in a table? Or is NaN not applicable in this case? How can I solve this?   Worksheet attached (prime 7). Thanks in advance!         

The latest version of Mathcad is 10 but my company uses version 8. So will it be possible for me to download the 8th version of mathcad.

working on a table with a long list of items. need to query the table to see if an item is listed without erroring out every time.   how can I check to see if "Black" is on the list and return a "N/A" or something I can use? Any help will be appreciated.  Ed.

I get this message when i try to configurate my floating license "Failed to configure license for PTC Mathcad Prime 10.0.0.0: '.', hexadecimal value 0x00, is an invalid character. Line 6, position 1" and i dont know what to do? It does not matter what i type, i just comes with that message 

I am using Mathcad Release 15.0 and Datecode is unknownWe have been receiving a "Disk Full" error when saving to a network location (that is most definitely not full). My users say it has been happening "for years," but this is the first I've heard of this. This happens regardless of the file or network location, and does not happen when saved locally to the computer. Happens with or without auto-save being enabled.When it happens, our users have to save locally and then move the file to the server. Is there a port or something on our firewalls that needs to be opened to allow MathCAD to save to network locations without an error? It doesn't happen every single save, but it is is frequent enough to where my users are choosing to save the file locally instead, which is an issue we'd like to stamp out immediately.Here are the errors that I faced:Disk full while accessing "insert network file path"

From Val Ochkov:   How to solve the lens problem in Prime?  

Hello everyone,I am a new mathcad user. I used to use python but we switched to mathcad prime 9 recently. I'm having a lot of trouble carrying out simple tasks with mathcad. It's certainly my beginner level on the software that explains this. I'm calling on your expertise to help me on a few points. Sorry if for you it's trivial but for me on mathcad it's really complicated at the moment. Here's my problem: I want to retrieve data from a calculation. I've written several fairly complex functions and I want to vary some of the parameters of these functions and retrieve the values. I then want to use Excel to plot the curves of these functions. I want to compare the curves for a given parameter, so as to visualize the impact of a parameter on the function.Mathcad Prime 9.0

Hi Mathcad community members,   For those of you who don't know me (some do), my name is Andrew McGough and I'm the product manager for Mathcad here at PTC. I have talked to some of you in the past individually, but I don't get to participate as much as I'd like on the community. I hope this announcement is the start of me being able to be more active here.   I would like to share with you that PTC is announcing the end-of-sale for the following versions of PTC Mathcad, effective December 31, 2021:   Mathcad 15  Mathcad Prime 1.0 – Prime 6.0     Effective January 1, 2022, the only version of PTC Mathcad available for subscription will be PTC Mathcad Prime 7 and future versions of PTC Mathcad Prime. After December 31, 2021, PTC will no longer have the right to sell or distribute software versions moving to end of sale due to a third-party component contained in those versions.    I appreciate the passion o

Hi to everyone!I'm a newbie here and need help finding the idea for the solution to my issue—a brief explanation of the problem.Mathcad Prime 9.0.0 is used for the modelling.There is a FOR loop for which data is calculated, and there are conditions for selecting the coefficient. If the condition is TRUE, I want the program to choose the k1  and f values to be represented in the augmented matrix in the output.But, as I can guess, the problem that prevents my loop from performing as it should in the type of input variable - each i-th value of the input variable u-value has to be checked for a condition—if it is TRUE, it goes to the list of output values; if FALSE, it returns an empty matrix.Mathcad doesn't seem to recognise the particular u-value; it simultaneously recognises all the set of u-values [matrix]. Thus, I probably have the error message "this value must be a scalar."PS The attached file could clarify my issue. I would appreciate any information and help you can give
