Mathcad

I have a Mathcad Prime license, with Mathcad 15 software associated.I successfully moved Mathcad Prime to another PC, thanks to the fact that I got from PTC the new license and I have the source and installation software on a CD.On the other side, I couldn't install Mathcad 15, because in the past I downloaded it on the old PC from PTC web site, but now I cannot manage how to do this.Please, help me in installing Mathcad 15 on my new PC.Thank you.Sarah Bollanti

I can not open any file using Matcad Express. When I click on open and navigate to Matcad 15 files, I do not see them. Also, if I open a file using the XCMD convertor and add a Matcad 15 file to workstation to convert it, it doesn't work.

Hello, I am trying to solve a series of two first order ODEs, the ODEs are a function of time but also include a piecewise temperature component that varies with time. I believed at first this is what was breaking the solver but when I make the temperature constant the solver remains broken. Can anyone see where my mistake is? I am thinking it is most likely the constants and/or initial conditions.    Thanks for any help that can be provided. 

Hi i make a new calculus for free fall with linear friction i can see the theory , but i have difficult to talking to Prime 😅 and chart! i have this:   But i can't make a chart !!! unit problem I think in the same way the evaluation of the limit does not give the expected result    

I need product code. couldn't install

Hi,I received the installation link for PTC Mathcad Prime 7.0, but when I launched the installer no program is found to be installed.Has anyone ever had this issue ?

Hello, Can someone help me with this? I want to translate some Matlab code into Mathcad 15.   Thanks.

hi,   i've never used symbolics before and i'm having a bit of trouble. i attached the worksheet in question. i'm trying to solve for v1 and v2. however, u1 and u2 are also coming out of the Find function. i think i'm missing something.   thanks,   anthony

I'm doing a simple calculation as shown in the picture attached. E has units of psi F has units of in A = (EF^3)/12 A should have units of lb*in, but Mathcad gives it the unit of (lb*ft^2)/(s^2)   Why is this happening?

I obtain Mathcad 14.0 Datecode: M020 around 2016. I haven't used it in a long time. Recently it seems to be acting sort of strange. I tried to repair it from Windows 10 Programs & Features, but it could not find a repair file.Is there an update to my installation? If yes, where is it located?If no, can you suggest how I can try to repair it?Thanks

Hi we have a old Mathcad 13 Network License server on one of our VM's, we are looking to migrate this to a new server (with new IP and Hostname), can anyone point me in the direction to how this is done?

Hello Dear Friends,1) How long or how many years from now do you think that Mathcad 15 (not Mathcad Prime) can still be used?2) And how long do you think that Mathcad Prime will outperform Mathcad 15 in terms of functionality and performance?Thank you.Best regards.

Does Prime 7 have the mathcad functionality: of check boxes etc as Mathcad 15?  

Been using express Version 4 for years. Trying to download version 7 never received e-mail with download instructions or the softwaregoran@forshager.comgoran forshagerForsHagerGroup

hi,   i'm still having problems trying to work with the output of the state space solver. it might be something simple, but i've been going in circles all day. the first problem is the plots look a lot closer than the table output. the second problem is there is a lot of error compared to the odesolve output. it's pretty easy to work with the odesolve output. the state space output has been giving me problems for days.   basically, i'm trying to compute velocity, acceleration, and kinetic energy from the state space output. the velocity doesn't match compared to what the solver outputs as the last column of the solution matrix. the acceleration doesn't seem to match either. i'm not sure why, when i plot it, it looks like it is matching. but if i look at the output in tables it's way off. i attached two files. the odesolve one seems to be fine. the state space file has been kicking my butt.   thanks,   anthony

Where exactly is this "Options list" ?    

Why is n taken as length(y)-1 rather than simply the length of y? In both Mathcad 15 and Prime 6, sometimes this seems to result in throwing away one observation. E.g., in the Prime 6 example, there are 12 observations, but only 11 show up on the plot.

Moving to Mathcad Prime is challenging Can someone help me with how to call excel data using drop down menus as we used to do in real Mathcad Also, can I make drop down menu reference excel data or to insert equations?

  Hello everybody. I have a problem for solving this equation in the first image using Math cad prime's solve block and the find function I have instead solutions this question mark. The 2nd image shows the solution of this exercise in Math cad 15; I am stuck trying to find the same solution as image 2 in Math cad prime. Thank you for your answers  

I am using Mathcad Prime 7.0 7.0.0.0I have a user that is having a strange issue where when she double clicks a Mathcad prime file a new instance of Mathcad opens for each file. I have already done a clean install of prime where I cleared the PTC folders from the computer and the registry. i had to do this because a few days after installing prime 7 it would not open at all on a couple of computers. After the clean install, this issue came up. I tried to replicate the issue on another computer by going through the same process but that computer works correctly. Any ideas?

Mathcad can't get the license. What do I need to do?19/04/2021 11:55:04 : The license request failed.Requesting MathcadPrime ...C:\Program Files\PTC\sw_license_email_5246793.dat: (-103) Cannot checkout an uncounted license within a Windows Terminal Services guest session.

I am facing a problem and can't figure out what is going on. I have seen previous posts on the community but not able to grasp the concept of vectors. Please, someone, explain the difference in clear terms so that nothing remains ambiguous. The first problem is I am trying to return two vectors in a 1x2 vector. This means it will be a nested vector. I have seen some posts where it is done but when I try to do it, it gives the dimension of a vector rather than the vector itself. Of course, the problems resolve when I use the augment command but I want to know why it is not printing the vector. In the below figure (obtain from the community) the D shows the vector elements but when I try to display it again, it display the size of the vector 😫 Similarly, the second problem is that when I try to plot vectors it says, "These array elements must be scalar. They cannot be vectors or matrices". But when I search the community there were examples where these plots were made. So, I am confuse

My MathCad document stopped working with this error message, and I cannot get it working again. I have attached the document here, and a picture of the error message. What can I do to make it work again?
