I'm noticing that my ports are automatically getting reset/stopped. Trying to determine if an AV Exclusion needs to be configured?

It says that I've reached the maximum number of license request available from my product type. Please help me

I am trying to use custom units in MCP v11. I have an included worksheet that includes a lot of domain-specific units and functions. This has been carried over from MCv15 and previous. I am now noticing that some of these definitions aren't working - I have distilled everything down to one simple example of success and failure, with no apparent reason why. See attached.I also tried to do my due diligence and see if anyone was reporting anything similar. Why there are lots of questions related to use of units, I didn't see a similar issue being reported.

MathCAD Experts,I'm trying to implement a model of a runaway reaction in MathCAD and I am stuck. I have tried everything including rewriting it several times to make sure that I don't have inconsistent units. I used the same variable definitions and then evaluated the derivative terms to make sure they were properly defined before defining them as functions. I thought I'd solved all my problems and now it's telling me that my initial conditions "aren't valid differential equations." Any advice would be most helpful.  I am using MathCAD 9.0.0Sincerely,Erik 

I am using Mathcad Release 15.0 and DatecodeunknownMathcad has not been opening for the past two weeks (no error message appears). The issue seems to be that the required file MSXML 4.0 SP2 was removed for security reasons, as it is outdated. The IT-department does not allow the file MSXML 4.0 SP2. Is there any workaround for this problem?

I can't download MathCad Prime 11. It says, there were no support avaiable. However, we paid the bill in March 2025.

I am using Mathcad Prime Release 11.0 and Datecode11.0.1.0I'm a system administrator needing to upgrade Mathcad Prime for our engineers. They are currently running version 9 so I have downloaded version 11. It appears I also need to upgrade the licensing server. Can you point me to the steps I need to take to upgrade licensing server? Will I need a new license key.

I need to write this equation this way > however the left part can't be written like ( 1/k)Thank you  

Hi there I tried to input the results from another mathcad file , but I guess I'm doing that wrong > in the following image I'm trying to import the results of ( R) What is the correct function to import the results from one mathcad file to another?When I searched in the community I found very old version which doesn't open in my laptop ThanksYusra 

Hello community, I have this problem:"How could I program it to sum 3 consecutive values in a vector (m), with the condition that the sum is performed only when there are exactly 3 consecutive values; otherwise, the result should be an empty string ('').""What I’m trying to do here is: in vector (a), if there is even one false, the result should be false; but if all values are true, the result should be true." 

Dear all, I have a problem with the step range. I want to prevent the value 0.50 from appearing in the first term of the function f(x1), according to the first method. I tried using the `last` function, but I can't get it to fit the vector x1.I have Mathcad version 11.Any suggestions?  

I have two problems defining the spectrum:1. Acceleration spectrum2. Displacement spectrumI tried to replicate it in Mathcad 11 without success. I followed an example created in Mathcad 13, which includes the Boolean function formulations, but the program detected errors because some variables are not defined, preventing me from graphing them.Please clarify what I'm doing wrong.  

Is there a function to convert from decimals to fractions?

Hello All,I’m not sure why the textbox result in P10 doesn’t have a red box around it, while the one in P11 does.In P10In P11Regards,Sam 

Hi there ,To be honest I don't even know I need to multiple selective values in a matrix with selective values in another matrix . I used ( submatrix function ) however it didn't work :where m is a row number Here I want mathcad to multiple the first three values from both d and z Can you help me doing this ? the sheet is attached Thanks Yusra  

Hello Community,  Please find the mathcad file in the attached it was developed in PTC91.In the following after the symbolic evaluation the units are not simplifying, for instance Ohms*Faradsshould be seconds, and Farad * Voltage should be Columbs, but 2.After Q2 as assigned as the result after the integration, when I try to call on Q2 it cannot be found, can someone please explain? Thanks 

I'm using WRITECSV to write the contents of a matrix to a .CSV file. The WRITECSV function writes the contents with full precision, giving me numbers with 18 decimal places. I want to round the elements to a few decimal places. I wrote a function to do this, but it feels kind of clunky. Is there a native way to accomplish what I'm trying to do? I'm using Prime 11. 

Hello!!i am kind of new to the program and I have researched but still can not find the answer. I tried to create a solve block where I can get the final reult of a variable H_2 but it does not work.I upload a PDF of the problem. I believe is not difficult but perhaps I am missing something

Why doesn’t Mathcad Prime 11.0.1 no longer accept ASCII code [13] for carriage return (new line)?It appears to work in version 10.0.1 but not in 11.0.1. Is this true for everyone else or just me?I have both versions on the same computer--is there something I am missing?   

Hi there,I am trying to fetch the required gross concrete cross sectional area of an RCC column using the SYMBOLIC Solver function as shown below. But I could not figure out what is causing this abnormal output. Could someone kindly clarify this issue? I would be much obliged.   

Where can I see the licenses I've purchased and when they expire?

The Mathcad rounding and truncation functions take the form function(z,y), where z may be complex but y must be real,   This is an unnecessary restriction and contravenes the Zen of Mathcad Rule 16.   This Mathcad Enhancement Proposal (MEP) extends the y argument to accept complex numbers.   Furthermore, the rounding and truncation functions operate only on scalars and vectors, not on matrices.  This is, again, an unnecessary restriction.   This MEP extends the truncation and rounding functions to accept matrix arguments.   The MEP further adds a function frac(z) that complements trunc by returning the fractional part of complex z; frac vectorizes over its arguments.    The MEP further extends the mod function to accept complex arguments; mod vectorizes over its arguments.       Stuart   Demonstration Mathcad Express 10 worksheet attached in support o

What I have here are two measured displacements over the same time with an equal interval of 1 second. Both oscillations tend to approach the resting asymptote, which is the same for both. The first one at the end of measurement didnt manage to approach, but the second did.For my task, I had to find periods and amplitudes of oscillations. To get periods, I simply used the difference between two interceptions of oscillation with asymptote via root() function. One of the arguments for this function is a guess points between which this interception should be met. For those points I pick local extremas (or peaks shortly). To get them, I need to know the first derivative of the oscillation function and look for the points where derivative becomes zero. But in my case, I have only empirical data, which I have to use to get proper constants a and w for the oscillation equation.Based on this, I created splines for both data sets, and started taking derivatives to find a slope.To get local

Hello All,Today I had P11 installed. It is worse than P9 and P10 combined in terms of speed. Also, I dont know why the Text Block, Text Box,  Image, Copy, and Paste  are greyed out.  Regards,Sam

Now that I have been forced onto Prime (changed employers, new install, 15 no longer for sale) I am really struggling with the keyboard shortcut for subscripting variable names. I get that there must be some good reason why PTC couldn't use . (period/dot) for it any more, but seriously "ctl -" is about the worst possible key combination they could have come up with instead - diagonal opposite corners of the keyboard making it a difficult one handed combo with lots of scope for mis-pressing one of the 2 keys and ending up creating some nightmare instead of the variable name you intended? I know word uses "ctrl +" and "ctrl shift +" (or something like that) for this, but the whole world doesn't have to follow microsoft's mistakes blindly. Please please please give us a single key shortcut for subscripts in variable names - is there somewhere we can start a petition of something to lobby for this? I am wasting hours and hours of time going back and re-typing my variable names because
