Mathcad

I am just trying to get my solve block to work. I wonder if I am inputting anything wrong. I know what the answer should be; it's a very simple calculation. However, I just want to get my solve block working. Attached sheet. Error on the last page.  sheet attached. 

I am trying to create a solve block to calculate the value of alpha as per the below equations:I have never used solved blocks before so hitting a bit of a stumbling point. I have found through manual iteration my required value of alpha as below:I am trying to put this together into a solve block, but not sure where I am going wrong:  I've attached the sheet pictured above also.Any help much appreciated, thank you. This will probably be a very simple solve and it is just my lack of understanding of the program hindering me!

I installed product with a license. In your instruction I just shall import the zip with licenses but mathcad want to have a product code.Shall unpack zip and make a .lic file by only use text from START: License File for HOST---#END OF THE LICENSE PACK FOR REQUESTBut I have two one im... and one im...Standard.

When I try to export a mathcad worksheet to PDF file, all the green (no error) boxes are also getting exported. Is there any way to hide then or switch it off when I export from mcdx. to pdf.? It`s a bit annoying when any of my clients see it that way with green boxes rounded off at random places.

Consider that, I have a data based upon the below image and I`d like to integrate that data with Creo so that I could sync up both. Now, "Number of Active Coils: Nc:=1" is assigned as input and the "Diameter of the wire: dw:=1mm" is taken as output. The issue I`m getting is that, I`m able to change the value of output as many time possible, but once if I assign a value as an input, it indirectly gets locked... Changing that value is impossible. What could be the reason for this? Am I missing something, or is there something wrong with the settings of my workstation..? Please clarify.- Srikar  

I applied for and received a license file because I was on my fourth PC, and the license only allows for 3 installations. I erroneously included the wrong disk volume ID. The correct disk volume ID is C272-D1C7 (for reference, the incorrect disk volume ID I provided earlier was 2A39-8A1A). I would very much appreciate it if I could receive a corrected license file for the correct disk volume ID. (Oh, and very sorry for the problem I have caused!) Thanks!

Is there a way to change the license server for an existing Mathcad Prime installation without using the GUI within Mathcad? I haven't found anything besides changing the XML file for silent installs, but that's only for before it is installed. I'm able to achieve this for PTC Creo by changing a line in the parametric.psf file and would like to do something similar for Mathcad. Using various versions of Mathcad- 9, 10 and 11.

I am trying to calculate the Jacobian (for a Newton Raphson scheme). At this point the problem is simple enough that I can derive it by hand but I want to make sure the two approaches agree (especially since my hand-derived result is nearly singular). What I am doing is not working - I get a "pattern match" error. Worksheet (in MC11) is attached. Thanks for any suggestions.

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.

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
