Mathcad

Have just paid for a licence to upgrade from MathCad Prime Express 12.0.0.0 to the full Prime version, hopefully 12.0.0.1. Following "Options|Get Licence" I have encountered a prompt asking for my product code. Where can I find this? Do I need to log in to the Fullfillment portal? Does it use the same general ptc account? It didn't recognise mine. When looking for help I am told I don't have access permission and haven't paid for that level of support. Elsewhere it says I have "Gold" level support. I an angry that you have now pointed me to a public forum where I can't post useful identification data. What a horrible mess. Can anyone help me get into contact with someone at PTC?

Hi, as you can seeat the bottom of the picture, when evaluting the function “Iresonance”, instead of replacing the variable with the actual, it gives “function” in the result, but the function “wresonace” is already defined. How to subtitute it? Thanks 

Hi, I’m just trying to get the real and imaginary part from a complex number, but the result is just not right.  

I can not contact a support department "access denied" to get a new licence file to install my Mathcad 15 on a new computer. Could you help me. I am desperate ! J.P. Collette jpcollette@walopt.com

Hi there , How can I work in Mathcad faster. it freezes when I use large data I have to use loop functions , however , it took so much time and doesn't calculate I have to close it and open it again and still doesn’t work  Thanks, Yusra 

I would like to use the result of a quadratic function for another mathematical operation. Example: F(x)=4x^2+x-3 gives the results -1.0 and 0.75. I would like to use the value 0.75 for another operation. Please give me some tips on how to write this in Mathcad.

Hi There , I always face this error and I don’t know how to solve this . I need to find the difference between 2 levels in  same z which has 4 rows like it do the same calculation for each row separately  Than I have to find the average and minimum value for this results  I attached simpler mathcad in zip file 

Hi community,I’m coping a program to make tables but get errors?What's wrong?Regards,CarlosRomero PD. This routine can be used with either vectors or your beloved ranges as arguments. First we create a function which tables a function with three arguments, so that the result is a nested array consisting of a vector of matrizes. Ever of those matrices shows the function values whith constant third argument z and x as rows and y as columns.

Hi Everyone I’m doing the same calculation in two different sheets , but I get errors in the another one although they are the same . why is that ? thanks Yusra  

pls i need this thing

Hello Could you please assist us activating MathCad 14 license. If not possible, I also have a license file from a PC that need to be moved to another computer. Best regards,

Dear all, Hope everyone is doing well. I am using Mathcad Prime 8 and I am trying to find a way to convert a pdf (originally a mathcad file) into a mathcad file (e.g. mcdx). There are formula equations in that file and so far when I try adding the file into Mathcad, the formulas are not recognized. Is there any way to do this? Best regards,Vich

It seems that my Mathcad version I have just downloaded Is Mathcad express Prime and not the Mathcad prime. Please check.

How can I make sure that e_max is added correctly … non of them has units , but still getting this error Thanks Yusra

Hi,Another Odesolve problem with an error I cannot identify. Google AI says its a syntax problem but I am damned if I can see it.Any assuistance would be appreciated.Regards, Ross

PrimeConnect C++ -> Prime -> C++PrimeConnect is a pair of C++ solutions/projects.One writes a *.mcdx Prime output file fully described by C++ syntax that encapsulates the mathematics of a Prime Worksheet.Two reads a *.mcdx Prime input file where all evaluation regions of a Prime Worksheet can be assigned to C++ variables in one line each.They both work on the underlying feature of *.mcdx files that are a collection of zipped XML files.  In the case of Prime text regions zipped up zipped files of text.The underlying XML text manipulations are handled invisibly by PrimeConnect. User of C++ can concentrate on the mathematics when writing a *.mcdx file.  User can concentrate on what are all the evaluation regions in a Prime worksheet are and assign them to C++ variables.Writes Prime v10 files, Reads Prime v9, v10, and v11 files without varying C++ code just point the C++ to a *.mcdx file.Both Microsoft Visual Studio 2022 C++, and Embarcadero RAD Studio 12 projects are available.  The

About Mathcad 14. I have just installed it to a new PC with Windows X11. When I try to run it, it asks me to run the license assistant. I do it, I get a web page asking to create a new account (although I already have one), so I create a new account, then nothing. Thanks for helping me. Regards, Michel Bonnardeau

Hi there, I don’t know why it shows this error here . I used the same function in another sheet and it is working Regards,Yusra

Hi there ,I want to write : if z_top,j > Hphr → use γ (unsaturated)if z_top,j < Hphr → use γsatbut I end up with this red box … the blue box is only using γ (unsaturated)can you please help me fixing this ?Thanks Yusra 

Hello! I have been trying to get the free version of Mathcad, but I run into a problem. I had the free 30-day trial on my previous laptop, and now Im looking for the free, express version. I downloaded from the Download .NET 8.0 page the .NET Desktop Runtime 8.0.28 and restarted my laptop, but when I press Download again, it takes me to the same page with .NET again. 

Hello! I ha previously downloaded the mathcad trial, then used the free, limited version. I have since then changed my laptop and am trying to download it again on my new one. I filled out the form for the trial/free version, but I have not received any email back (this was a few days ago). I also tried to download the program from the "download" shortcut, but after I restart my laptop and press download again, it keeps taking me back to the same page with the downloading links. I tried .NET Desktop Runtime 8.0.28 and .NET Runtime 8.0.28, both the x64.

Reference topicThere does seem to be a bug with Polyroots. I get the same error with the Quicksheet and a manually entered matrix of coefficients.If anyone can advise how to fix this issue  your advice would be appreciated. Ross 

 I recently started using Mathcad Prime 12 for structural engineering / Eurocode calculations and I noticed something frustrating regarding the unit system.Mathcad correctly understands that: kg/s² = N/m. However when working with line loads (common in structural engineering), Prime often displays results as “kg/s²” instead of the expected engineering SI unit: N/m or kN/m.The strange part is that under “Insert Derived Units → Force per Length” there are several imperial units available: kpi, klf, plf. but there is NO SI alternative such as N/m or kN/m.This creates a awkward workflow in SI-based calculations, especially for Eurocode and structural design where line loads are constantly used.Currently the only workaround that i found seems to be manually dividing by (kN/m) , creating display variables or manually writing the unit as text. This partly defeats the purpose of the otherwise very capable engineering unit system.Questions:Is there any hidden way to add custom SI derived units

Hello All, The following symbolic evaluation used to calculate without any issues in mathcad 15. It does not evaluate in Mathcad Prime 11.0.1.0. i have attached the sheet,Regards,Sam   

Hi all,Last week we released PTC Mathcad Prime 12.0.0.0. We’ll be sharing more detail on www.ptc.com soon. A handful of users reported an issue with the release.Currently, PTC Mathcad Prime 12.0.0.0 will not run if it’s installed on a system where the system language is set to one other than one of the ten languages officially supported by Mathcad (US English, French, German, Italian, Spanish, Japanese, Korean, Russian, Simplified Chinese, and Traditional Chinese). If you run Mathcad Prime 12.0.0.0 on a system using one of those supported languages, there’s no problem. If you can change your system language to one of those supported languages, Mathcad Prime 12.0.0.0 will run fine. But if you need to run Mathcad Prime 12.0.0.0 on a system language not officially supported by Mathcad, you should remain on PTC Mathcad Prime 11.0.1.0 until this is resolved.We’ve been working closely with Microsoft on this issue and have identified a fix. We’re currently in the process of building and testi
