Mathcad

I have change device and it seams that i can't download mathcad express. please i'd like some help.Thank you very much.

I purchased a student license for mathcad prime, but when I download my activation file and activate prime 11, even if the license manager says to be activated successfully, the program opens with the express version and says the release is not supported, version 10.0.1 works well.  

HeyI have a license for MathCad 10 but I can't figure out where to download it, I can only put the license on my MathCad 9 or the MathCad 11 I recently downloaded, can you please help me with a download link to MathCad 10.Thanks.Best Regards,Benjamin

If I use the Include Worksheet function in Mathcad Prime 10, will the worksheet called within the Include Worksheet function path then open and fully run, when calculate is commanded for the primary worksheet?  If I use the Include Worksheet function to call multiple worksheets throughout the primary worksheet, will each of the included worksheets be opened and fully run in sequence when the primary worksheet is calculated?

Hey!Im trying to download mathcad express, but somehow I dont get email where download link should be. This is crucial bc I have an exam in few days about concrete desing and I have to use it to calculate stuff.Aaro Ilola

This feels like a silly question, but I have not been able to figure out how to find and replace text in Prime 9 from the help or other posts. 

Student assignment and learning from the software

I tried a couple of *.mcd and *.xmcd files. In one case a red "Keine Lizent" appeared, no other resonses. But no new file was created, neither in the original folder nor in any other folder. The issue was even described earlier. The found "solution" was finalised with the recommendation to contact the support. But it is not possible to open a support case (probabaly due to the trial version), although I have an old user account.

Hello. I came upon an interesting case: singularity function defined in my particular case as < r - r_o >^0It is also said that if r < r_o then the whole function is equal to zero.  Do we have any means of evaluating this function in Mathcad, such that, if I plug inn any values of "r" and "r_o" into the function, it will return to zero (of course if r < r_o)? Otherwise this function is always 1 (if r > r_o and if we ommit the case when r = r_o). Best regards,Sergey

This variable is not defined. Check that the label is defined correctly.The variable is defined, redefined, calculated, recalculated, but it still shows me a red error when I include the variable in an equation.

Hello! Does anybody know how to change the units (from m to mm, m^2 to mm^2) in the chart component graph?Please, take a look at the attached file. Best regards, Sergey

The  error is - "The value must be a scalar"

Good morning to all, for my calculation I've to deal with badly conditioned matrices. The matrices includes terms with its own unit of measure. The bad conditioning is coming (also after some simple numerical tests) from the very different order of magnitude of the terms and it could be reduced introducing, new, custom unit of measures (such as for example MegaNewton for example). I know how to introduce custom unit of measures in input. BUT what I want is that for an entire spreadsheet (or even a region) a custom unit system is used; said differently I want that the results are in the custom unit of measures: how can I do? Many thanks in advance 

I upgraded from trial version to student version and the process completed successfully, with all functions unlocked. About a month later I opened Mathcad again (10.0.1.0) and all functions were locked. I tried to use the PTC option menu and then the get License button. The response was as follows:4/22/2025 2:42:15 PM : The license request failed.Requesting MathcadPrime ...C:\ProgramData\PTC\Mathcad Prime\license\MathcadLicense.5.dat: (-9) Invalid host.I don't know why all of a sudden the functions were all locked as if in Express mode.The Cleverbridge reference number: 496916359Invoice number: BKD-73652662548Invoice date: 3/16/2025

This month’s challenge is based on magnetism. Create a Mathcad worksheet to answer any or all of the following:Basic Challenge:   What is the magnetic field strength of 15 Ampere current in a wire at a distance of 0.25 meters? How many turns of wire will be needed to create an electromagnet capable of lifting 1 kilogram of ferrous material if the current is 0.25 Amperes, the lifting face of the magnet is a circle with a diameter of 5 cm, and the length of the coil is 0.1 m? Assume a relative magnetic permeability of 750. What is the total magnetic energy of the Earth? (Assume a magnetic field strength between 0.22 and 0.67 Gauss.) One resource for the equations to solve these problems is NASA’s Magnetic Math ebook.   Graphing ChallengeCreate a 3D plot of the force generated by an electromagnet as a function of electrical current and surface area of the lifting face of the electromagnet. (Choose any values you want for the other parameters of the electromagnet.) Creative har

A sample of a variable name containing a superscript and subscript in the math formatted region is provided in the attached Mathcad Prime 10 file. I would like to edit the superscript to make a new variable name. I can edit everything except the superscript. Please advise on how this can be done? Please see attached file for more information.

I wanted to play with the advanced control Button Example with python script. I have different versions of python on 2 computers:My next step would be to download a newer verson of python onto the computer that fails and see if the problem with the control is resolved. But: how do I know which version Prime needs/uses? There doesn.t seem to be any documentation in Prime 11 other than a statement along the lines of "Prime will register python and enable python scripts". 

Hello, anyone knows how to change the background color of mathcad prime 1.0 sheet.thanks in advance for your help.

I solved a statics problem with Mathcad Prime 10 like this:Can any member suggest an elegant method to do this?

Afternoon,I am using the Mathcad Prime 10. I'm fairly new to Mathcad so there may be an obvious answer to this. I have a few graphs like this, and am needing to determine the value of v for each curve (green/blue) that gives a Y value of the red line. Is there an easy way to do this? Also, unrelated and mostly a formatting request, the Y-axis is Pressure, and will only display in Pa, I would prefer psi for this situation but cannot for the life on me figure out if I can change it. Any ideas? Thanks for your help in advance.

 Does anyone know why this is happening? I set all the "B" Labels to "Variable" and it still says undefined.   I got this example from a youtube video and it gives a different error.  This is pretty frustrating, not gonna lie. I am new to mathcad, so maybe it's something I'm doing.Here's to hoping you can help.Thanks

Can you change the color of the Mathcad sheet background? Why is this still an issue in 2025?
