Mathcad

I am analyzing a ground motion applied to a SDOF structure and finding the motion with Newmark's method. To accomplish this I have read the ground motion in with the readexcel function and then use a for loop to find the relative displacement, acceleration and velocity for each time step. The file used and the needed excel file are attached.     

Hello all, I recently got an error message when I opened Mathcad file, attached below. Error message saysAre there any means to resolve it? Thank you so muchKind regards   

Is there a way to get the plus minus sign ± into math field? I couldn't find it from the symbols list so I guess the only way of getting it into the document is to copy+paste. However, Mathcad doesn't allow me to paste it into math-field, only to text fields...

When installing Mathcad Prime, in the third window the application selection menu is empty. I've run the .exe file as administrator and the problem persists. Any help would be appreciated. 

Hi,We have an old LMTools running providing an license for MathCad 11.I would like to transfer the license to a new supported server, but I'm stuck with the license file itself.I did manage to start the license server, but I'm receiving an error: (mathsoft) Invalid license key (inconsistent authentication code)I cannot find any contract, customer nr or anything, so I cannot create a case with PTC.Can anyone help to transfer the license to a new server?Thank you     

Is there an option to make default input type text and not math? I'm doing a machine design course and we have to use Mathcad to calculate the exercises. Majority of the document will therefore be text so it would be more convenient if it was the default option. Meaning that if I just start writing, it'd write text and not math. Math-field could then be activated using [ctrl] [m]

Hello everyone: I have a question about how mathcad prime handles the units in the background. See attached Mathcad Prime 3 spreadsheet for reference. Why does the top formula (i.e., the one where the variables have units) get a different answer than the bottom formula (i.e., the one where the variables don't have units)? Shouldn't it be the same since, in this particular formula, all of the units cancel out? And how is this program handling the units in the background? Does it use default units under the hood and then convert from those default units to whatever units you type in? Thanks in advance for your replies.

Hello there,I am new to mathcad and in my start I got a strange result: I am deviding a length of dimension m by a constant number and the result is not what I was expecting    H:=10 m soil layer thickness N:=5 number of calculation layers Dz: = H/N Dz= 400        

PTC must have the most user-unfriendly support site I have seen. I want to check the expiration date of my current Mathcad support agreement, and even after logging into my account at tpc.com/support I cannot find that information. How can I check the date? If I look at the "extra" license file, it has an expiration date of 30-APR 2023.  Is that the same as the expiration date of my support agreement or does the license file have a grace period? Victor Roberts   

I have a permanent license for Mathcad Prime 3.1.  My laptop motherboard on this computer failed.   I've replaced the motherboard and can no longer use Mathcad.  When trying to get another license, I can't, since the software on the PTC site indicates that my product code is incorrect.   I'm currently retired (2016), and would like to get this working.   I'm not paying support, since I'm happy with the current versions Mathcad 15 and Prime 3.1.   Can someone guide me to the right person/contact? Thanks!Larry Callis 

Recently I have been having an issue where MathCAD Prime will nto run on my PC anymore. It loads the splash screen and then nothing happens afterwards. Looking at the task manager, a PTC MathCAD process begins but disappears when the splash screen disappears. I have followed the steps in the other relevant forum posts (below) and contacted PTC technical support for help with this issue but the only fix was to completely reinstall windows. Uninstall/Reinstall does not help, nor does copying config files from a PC where the software is still working. Compatibility mode does not help either. https://community.ptc.com/t5/Mathcad-Installation/Prime-4-0-does-not-run-anymore/m-p/803946https://community.ptc.com/t5/Mathcad-Installation/Mathcad-Prime-does-not-launch-after-the-initial-splash-on/m-p/729884 Now, 2 months later the same issue is happening again. There are no other issues with my computer, everything else runs fine except MathCAD Prime. It does not matter whether it is

I am unable to acquire a new license for Mathcad express after changing the laptop. With no access to license management, how do I get an updated license with the new Host ID?

Does anyone know how to speed up MCP for processing large data sets? I am working with a 50832x14 size data set that is output in Excel from another program. I would prefer to filter, sort, and manipulate the data in MCP vs Excel. However, trying to execute a simple filter step in MCP on a data set this large has proven impossible. I can't get the function to complete (endless spinning wheel). Whereas I can complete this one step in Excel in about 1sec. Does anyone know how to speed this up? Or any other tricks for processing large data sets in MCP? I would really, really prefer to avoid Excel but at this point, I'll have to use it.Thanks!     

In the thirty-day trial.  Hoping this "bug" (see attached .pdf) turns out to be my mistake, because if not, PTC will have lost a customer.  

I have an old file that colleagues developed and they created variables like this: Rop%.  I'm trying to re-create and improve some plots, which use this variable, among other similar definitions.  When I retype the variable name, Mathcad tells me the variable is invalid; undefined.  For the life of me, I can't figure out why.  But it looks like the percent signs (%) have different fonts.  So it looks like there's something different about them, but I can't replicate it.  Please see attached.   

Does anyone know how to reduce the file size of a MCP sheet or other ways to speed up processing? I am working on a big calculation package that reads in Excel data (~30000x15) and manipulates it various times (loads of filtering, sorting, assigning submatrices, etc.) that is going on 20-30 pages. Now the file size is almost 18mb and the sheet is moving very slow and takes a while to save. TOL and CTOL are set to defaults, and I am trying the multithreading option. Only working on one sheet at a time. Are there any methods to speed things up? Maybe purge past data once a step has been made? I don't have much experience with the clear() function, but could this be of use here? Open for suggestions. Thanks!MCP 8.0, Windows 10 Pro.  

I am trying to install a temporary mathcad prime free trial and I am not sure how to install the temporary license.  Any instructions that can be provided will be greatly appreciated. Thanks.   

Hello.I received an activation code from my university to install MathCad Prime 6.0.I can't find where to download it.I read that it is no longer available and the licences are transferred to Prime 7.0, but maybe i understood wrong.Please help me.thank you.

I am trying to download my licensed issue of Mathcad . Clicking 'download' link takes me to the page to select the version I want. The only version available is PTC mathcad Prime 8.0 Student Edition - datecode 8-0-0-0 - which then states is 'unavailable'........ Thank you.

Hello, I need to have a conversation with support, licensing for ths product seems to be a joke and I am having issues. Brand new customer, just purchased the software.  no phone numbers for support is such a pain.      

We received an email inquiry which I had forwarded to a Mathcad product manager. I thought it may be useful for others, too, so instead of just emailing the response to the customer, I am posting it here as well.   ------- We need to convert .mcd to .mcdx...We have Prime 6.0.0.0What do we need and how much does the program cost to do this conversion. ------- The .mcdx file format is Mathcad Prime. The .mcd file format is for earlier versions of the legacy software, later versions of the legacy software use the .xmcd file format.   If this customer uses Mathcad Prime 6.0 there is a converter that comes with the software they can use to convert all .xmcd and most .mcd files to .mcdx - ‘most’ .mcd as we only go back as far as something like legacy Mathcad 7, which was late 90’s I think.   From the Input/Output tab in Mathcad Prime 6.0 they can find an ‘xmcd/mcd converter’ button - clicking that will open the converter. They will need the latest version of Mathcad 15.0 (M050

 Hi! I surprisingly found that Mathcad calculates this simple expression wrong:  Both results must be the same. The second result is the correct one.It gets even worse in this case:  It seems that Mathcad accumulates floating point errors in sums, which can be easily avoided (or greatly reduced) by applying a proper summation algorithm. It costs nothing to implement, so why not do it?

Hello,   Unfortunately, since a new installation, it is no longer possible for me to set a valid license.dat. The present files end with the note that they are not valid. I only get a timeout error over the Internet with a user and password. What can I do to activate Mathcad 14. Thank you in advance for your efforts!   Best regards Udo Wilczek   Google translate Translated by - Anurag Singh Date - 02/24/2023     Hallo, leider ist es mir seit einer Neuinstallation nicht mehr möglich eine gültige license.dat  einzustellen.
