How can I force prime to reserve Secant (inverse of cosine) in the solution?  In general, how to implore a particular format to appear in the solution?

Hello, Please see the attached problem for a piping system. Essentially I have the flow rates in and the pipe length and diameters and I am trying to solve for the flow rate in each leg of the piping system. This is example two in the attached Mathcad sheet. I will attach the tutorial below (from older Mathcad version).  The problem I am having is that the results produced by Mathcad from the solve block is not satisfying the equations for flow rate (see the last page on my attached worksheet). I am fairly sure the equation have been set up correctly so I don't see why Mathcad is accepting the answers I get as a solution when they are so far off from the constraints.  I have tried the following so far:1. When using the find solver I get the error message that TOL/CTOL cannot converge. After playing with the tolerance I can get a solution using this method if CTOL 10^-2. I was thinking this may be why the constraint criteria is not met.  2. I have also

Hello all,  Relatively new here and no experience using mathcad prime however I was looking for some guidance. I am working through a tutorial and trying to solve the following problem for lambda. I am not sure where I am going wrong with using the solve (lambda) symbolic. From the looks of it possibly something to do with the pressures?In the tutorial the solve symbolic yields the following:  Any help would be appreciated.Callum

Dear PTC community,   Problem description: The following picture shows the input data for my calculation, where I need to enter repetitively the property of each corresponding layer for calculation. Generally, the outer and inner layers are the same material, what repetitively change is the middle layers. Goal: To simplify my input as it is repetitive values. Is there any way that I can simplify or reduce the amount of input with programming? If so, can anyone give me an idea of how to start, or which function to apply?   Many thanks for your help.   Please find the attached Mathcad Prime 6 file for the above question.

Hi all, is it possible to combine the two graphs and formulas I have set up,to get the two graphs they produce shown in one?I don´t know how to solve it as the two formulas have two different boundary conditions. RegardsSeb

Hi, I am a student that is new to Mathcad and am having a lot of trouble getting a solve block to calculate the value of 2 separate variables with an indexed input. If anyone has any knowledge on how to get mathcad to do this, it would be very appreciated. Thanks

Hello! I'm new to MathCad and I'm having trouble solving a kinetics and reactor calculus problem.I have to find the temperature at which the concentration of B reaches its maximum value. I did this by manually guessing values, but I was wondering if it's possible to do it in an easier way.The constants k depend on the temperature. The concentration of A depends on the constants k. And finally, the concentration of B depends on the constants k and the concentration of A. The temperature I found was 306K. Would it be possible to synthesize all these calculations in a solve block? The following is the resolution and the way I was trying.

I am having difficulty figuring out what is wrong with my worksheet. This worksheet is a design calculation of spur gear. My problem is that addendum, dedendum, and clearance units are in 1/in, which is wrong. Why is it that the units are in reciprocal form? Is there any solution for this?. The goal is that the addendum, dedendum, and clearance must be in plain mm or in. Hoping someone can help me. Thanks

Hello All,I want to look at an XMCT file.For this I got the 30 days trial version PTC Mathcad Prime 7.0.0.0.When converting the file I get the feedback "Failed".What can I do to be able to work with the file after all.Sincerely Nikolaj   Translated with www.deepl.com Translated by Corina Ionescu, March 2nd 2022   Hallo Zusammen,ich will mir eine XMCT-Datei anschauen.Dafür habe ich mir die 30-Tage Testversion PTC Mathcad Prime 7.0.0.0 geholt.Beim Konvertieren der Datei bekomme ich die Rückmeldung "Fehlgeschlagen".Was kann ich machen um doch mit der Datei arbeiten zu können.MfG Nikolaj

Windows 11 will be released as early as next month. Has anyone done some testing of the existing versions of Mathcad (i.e. MC15, Prime 3-7) to identify issues under Win 11. Personally, I have a perpetual academic license for MC Prime 3.1, and as a retiree, I am loathe buy a subscription version. Furthermore, I have had to reinstall MC Prime 3.1 several times and it has never been an easy task. Unless I am reasonably certain that an upgrade to Win 11 will not be an issue for Mathcad Prime 3.1, I will simply stay with Win10.

I have a MathCAD model that reads raw data from a CSV file and plots it.  It was working fine but then when I read a new set of data the plot trace lines became very thin and the option to edit them is grayed out now.  Is this a bug or something?  I have between 54,000 and 250,000 points but it was working previously.  It just switched when I read a new data set.  Here is how it should look and does look with one dataset: Then here is how it looks with a new data set, the trace thickness becomes very thin and the option to change it is grayed out...This issue is occurring to multiple plots in the document, here is another example:...and here it is with the new dataset:I need to find a solution.  Please let me know if you know what this is. Thank you!

Here is a simple math challenge for you. Solve with MathCAD! On a regular 12 hour clock, how often does the minute hand pass the hour hand?(Hint: The answer is not 60 minutes.)Edit: I'm looking for the amount of time it takes for the minute hand to pass the hour hand. I will post the solution in 1 week. Kudos abound!

HeyThe last week i have been working on a Mathcad-file with som notes. But suddenly i couldn't open the file?What is going on?  The file is 3,82 MB so there must be some data? The filetype i MCDX and i use Mathcad Prime 7.0.0.0 I have attached the file as a .zip - hopefully someone can help?  - Valdemar 

Hi, I have a combo-box with in a mathcad sheet that I would like to change through Excel + VBA. The combo box is something like this:option1 ¦ 0option2 ¦ 1etcThe idea is to change from excel the state of the combo box. I can add it as an input, so it seems possible but I don;t know what variables I need to pass. I tried "option1" and 1 without luck, VBA tells me that I cant pass that variable to the combo box.Anyone has experience with this? Regards,  

I know, this is a terrible place to ask this, but this is where support routed me.I switched machines and no longer have access to my Mathcad Express download link. Anyone know how I can get the download again? I still have the license file, which I assume will still work - I just need the software download.Thanks!

I am having another MatchCAD Prime issues. Plotting simple equation in MatchCAD 15 worked. After transfer to Prime the graph - Plotting failed. Replace complex values and NaN by real numbers. I can't see any issues here. My Balance Now 

My laptop has become broken. So I installed Mathcad on my new computer, but on my new laptop the license code does not work anymore. It says when entering the license code: Program ID not be expired. Translated with www.deepl.com Translated by Corina Ionescu, Feb 28th 2022   Mein Laptop ist kaputt geworden. Deshalb habe ich Mathcad auf meinem neuen Rechner intalliert, aber bei meinem neuen Laptop funktioniert der Lizenzcode nicht mehr. Es steht beim eingeben des Lizenzcodes: Programm-ID not be expired.
