Mathcad

I'm trying to activate the product online, but can't do that due to server error. I need this pretty urgently please. Best regards, Michal

So below is my email transcript trying to get a valid product code for Mathcad 8 purchased last month.  The email they provided bounces (not monitored).  I was able to finally get through on the number for technical support and the person was confused why I didn't receive an email with the code.   He suggested I call the e-learning library support number because that package was bundled with the software.  No relief however.  So I guess my only recourse is to walk away from the software and my license fee.  This company is totally incompetent.   BUYER BEWARE!!!!! Dear Thank you for contacting the PTC online store. Please accept our apologies; all products ordered through the PTC online store are ineligible for a refund.

I keep receiving the error "an unhandled exception occurred on the dispatcher thread". I have tried different methods presented in the community solution section. However, none did work.

Hi I am trying to solve system of 2 ODE as shown below. I am unable to find out the issue. The error happens when I m trying to relate the first ode to the second one. I am getting error as "Unknown error: ode% _function% _illegal % _context. Please help! 

Same problem. Can you help me? Where to find contact wit PTC?

Hi,In the attached I show a simple example of referencing a matrix element with two approaches.  When I use ORIGIN:=1 the second method fails.  Is this due to my incorrect use of the second method? The 1st method uses the matrix index from Vector/Matrix Operators menu.  The 2nd method is just A(row,col). thanks,russ

Hi experts, I have some questions about the math calculation problems (case 1 and case 2), please see below description and the Mathcad file. For case 1: I have fire different resistance needs to be calculated. so I try to use two ways to calculate it.the first one is like that, I calculate every resistance separately and add them up to get the total resistance.but I think this is not a good way when I have a lot of resistance.The other way, I try to use the matrix way to do it. it is more convenient but I don't know how to calculate the total value by using a matrix.For case 2: I want to change the Width from 0.1mm to 0.91mm and also have 5 resistance.but when I try to define the Width from 0.1mm to 0.91mm. my calculation can't work.For example, if width = 0.1mm, I want to calculate the total resistance based on width = 0.1mmif width = 0.2mm, I want to calculate the total resistance based on width = 0.2mmif width = 0.3mm, I want to calculate the total res

What's going on?  I can't create a support ticket.  Has that feature been removed from PTC?   If not then provide a link.   I can't seem to navigate to an area to create a support ticket.   Whatever.

I created a case for this last year - but it seems that PTC has deleted all of the old cases (why?) - so now I'm back to zero again.    As always, I've paid for a license and would like to use MathCAD 15 - but, lack needed information for installation.  

I dont have the installation fileUsually I got this from my school teacher. But I cannot contact him right now and I need Mathcad for my exam

It happens from time to time (within week) that my Mathcad installation forgets the Server name in the License Setup Window. So I always have to correct the server location again and again. I don't have ever provided any "localhost" server, anyway it randomly shows up ... 

When running the PTC Web Installation Assistant, once I reach the Application Selection step, there are no applications available for me to select to install.

I've seen a couple of PTC articles showing a symbolic solve block using a 'dummy' variable in the solve variable list (which isn't represented in the solve expressions).  The examples involved inequalities.  They use  't'  and it appears needed to force a comprehensive result.  I attach a file with two examples. Does someone know the intention, and interpretation, of this dummy variable?

Hello, I am trying to activate/transfer our Mathcad license to a new computer. After clicking "activate" in Mathcad Prime 3.1, it displays the correct MAC address of our new computer, but it is also asking me for a product code to complete activation. Where can I find the product code? Thank you.

I am trying to log in to Mathcad (through the desktop application itself) to activate my 30-day free trial so I can complete my homework, however it keeps telling me my credentials are incorrect despite me verifying them numerous times. Any reason this might be happening?

I've converted a MathCAD file into MathCAD Prime (ver. 7).   For some reason the plot doesn't show.   The functions appear to be working.   Not sure what I'm doing wrong.  (see attached screen capture) EDIT - attached Mathcad Prime document

I get an email asking how difficult it was to renew.  I click the link - and I'm on a page where every thing is written in what looks like Chinese.   I don't read or speak Chinese.    The original email is written in English - so, how would it make sense to link a Chinese page?   This is just lacking common sense.  Oh, and I still don't have a license.    Whatever.

I find the calculation options in 8.0 very constraining compared to 2001i Professional, which I had previously used for 20 years.  In 8.0, if you don't enable "Stop all calculations,"  the program solves the entire worksheet every time a change is made in a subroutine.  In 2001i in auto mode there was no action until you dropped down to the page using the subroutine- and even then it only executed down to that page.  In 8.0 if you are converting several data files in the same program, it will execute all of them every time a subroutine change is made.  This can mean significant finger twiddling.  In the prior version, you could move back and forth from the subroutine to the first data set and optimize or modify the conversion process without the time penalty associated with processing the later cases.  Or is there a work-around? 

We are happy to introduce those two tools on the eSupport site!

These topics cover both locked license and floating license configurations. If you’re new to managing a Mathcad installation, the one-minute video on the landing page will explain the basics. The Guided Licensing & Installation Troubleshooter for PTC Products based on FlexLM is a one-stop-shop for the vast majority of problems and errors encountered when using a license server. Most FlexLM licensing errors have multiple causes. Within a couple clicks you can review the most common solutions for that specific issue. Many of these solutions have links that open a popup window for more detailed steps or a vi

Greetings, Across all industries, when we do math we often want to find the minimum or maximum point of a function. There are many ways, but the most reliable is to do it iteratively. I have built a function that does this. Attached is the function itself. Put it in a closed area at the start of your template so that you can always call it. The inputs of optima(f,x0,xf) are any single variable function "f", and the starting value "x0" and ending value "xf" of the domain of that function. It outputs the x value of the function at its maxima, the value at that x value, the x value of the minima, and the value of the function at its minima. It finds absolute maxima and minima of the function only. You can make a multivariable function be single variable by defining a new function of a single variable, where the other inputs are all constants. For example, f(x)=g(x,c1,c2,c3) This is the interesting part: To make it run quickly but still get a precise answer, I split the proc

I can't open mathcad right now, it's was no problem before to day

gtydghh

I am using Mathcad Prime Release 8.0 and Datecode8.0.0.0I have set of formulas with a units. If I change the unit on the result of the first formula the following formulas are loosing their unit.Here are the errors that I facedNo error message or warning. Inconsistent results.

Please have a look at the following example-function:If I want to plot this function with Newton (N) on the y-Axes and Millimeters (mm) on the x-Axes, the following happens:Unfortunately my Mathcad Prime 8.0 is in German, but the error is the following:Plotting failed. Replace complex Values or NaN-values with real numbers.Also you can see that it replaces mm with mm / m. If I erase the units out of the fuction like this:Then it will work, as you can see here: Does somebody know how I can fix this, so that I do not have to erase the units from my function?I will leave the mathcad-document attached here.GreetingsSpedex

HelloIm not able to activa my trial version anymore.The message, when i login is the following:"You have reached the maximum number of license requests available for your product type"I have tried to unistall an reinstall it many times now.Is it posiible for you to help me?
