Mathcad

To whom this may concern,  Looking for help on how to setup Matrix headers for the attached.  I would like to have a Title above each column for each variable, and the corresponding units shown in the matrix. See remarks in red within the attached.  Many thanks,Iain  FYI, I use Mathcad Prime 10.0.0.0

Dear PTC Support,I am a student at the Linzer Technikum (HTL Linz, Austria), using a full educational license provided by the school.I am unable to activate Mathcad Prime when I use my personal laptop outside the school environment (on a different home network/internet connection).The license activation fails with the error: "(-9) Invalid host." (License status "Ungültig" / Invalid).Steps taken and results:Using the License File: The license file (...sw_license_email_738123.dat) fails because it appears to be tied to a specific network/host ID present only at the school.Using the License Key: I have attempted activation using my assigned license key, but it resulted in the same error. I can provide the key privately. This also results in the same "Invalid host" error and the key then becomes invalid (or tied to the incorrect Host ID).Key Issue:This is happening on the exact same laptop. The issue is solely dependent on the change in the network connection. My classmates, who followed t

Dear PTC Community, I have Mathcad-11 from the 1990's, & I need to reinstall it after a HDD failure. However, PTC (Mathsoft) doesn't run their license server anymore & therefore, the product cannot be activated. Can someone please assist ?

Dear PTC Community,I am working on a system of coupled nonlinear equations and attempting to solve it using a Mathcad Prime 7.0.0.0 Solve Block. The solve block runs without errors and returns numerical values for my unknowns. However, when I validate the solution outside the solve block, I find that one of the variables ( J), which appears in two different model equations, gives two different values when recalculated. I expected these equations to converge to a consistent solution for J, but they do not.In other words, even though the solve block returns values for three different variables (J, E, ε), the two J expressions do not evaluate to the same value of J when I recompute them using the solved ( E and ε).I have attached my Mathcad file.Could someone please review it and help me understand why the solve block returns a result but the two governing equations do not match when checked afterwards?I would be very grateful for your insight. Kind regards,Tadele

Hello All, How do I solve for "a" symollically? "a" represents the maximum cantilever length. (0.125) is the maximum deflection in inches at the end of "a". I have attached MC11 sheet. Regards,Sam

Error message, reaching max no of licenses on my laptop even tho I just signed up.

Hi there,Any ideas why this is wrong? I made f as function of M in order to define it RegardsYusra

Hello everybody. I have a general question: How do I define the solution interval for the simple first/second  order DE?Example:The DE y**-9y = 0, has two solutions: y1=e^3x and y2=e^(-3x). How do I define the solution interval here? I need merely a simple explanation of how to proceed in order to find the solution interval (in general also). Linear independence:Question: What does it mean for the "real" world? What do we get by knowing that the solutions of a given DE is linearly dependent or independent? Best regards,Sergey

I'm planning to run Prime11 on a laptop Lenovo AMD Ryzen 7 4700U, 20 GBRAM 512SSD. MathCAD would run correctly, very well, badly? Thanks

Mathcad Prime 11 is ok with the units of atm and psi but has issues when trying to use bar and kpa in all but the SI unit system.   Why does these pressure units only are valid in SI unit system? For example, I get the following error messages when in CGS unit system: "This variable is undefined.  Check that the label is set correctly." When I switch back to the SI unit system it works and removes the error message.

Mathcad Enhancement Proposal:  Change Mathcad's numerical representation of infinity to the IEEE 754 floating-point standard.   When dealing with large numbers, representing infinity as 10^307 can lead to numerical errors and yield ambiguous or unreadable results.     Note: Python math, NumPy, Mathematica and Matlab all give correct results.   I don't know why 2^1020 is allowable, but 2^n, where n:=1020, raises an error.   Stuart   (Numerical ∞ = 10307 has annoyed me since Mathsoft Mathcad days.  At least change ∞ to ⧜ (U+29DC Incomplete Infinity)

Hi, I have a DLL with .Net Framework in c#. I want to integrate this Dll into Mathcad. I tried lots of method to integrate this but software didn't recogniz this Dll. I also add this Dll prime/Custom functions and the same file. I also make a wrapper dll with using c++ and add as reference this c# dll. But it doesn't work. Could you please help me?  

IMHO the first line should evaluate OK. Reason for Prime failing is because it automatically assigns the 0  an "appropriate" unit even though Prime is not using SUC (static unit check).  As a result, Prime naturally refuses to add 0 kg and the unitless 1. A unitless value different from 0 works OK as can be seen in the second line. Workaround (which should not be necessary) is using "zero" instead of "0".   There is no problem if the vector contains values of different dimensions or even      

MC15 allows a label to be added to an area, so when it's collapsed the label can be seen. In Prime 9.0 I can create areas but can't figure out how to add the labels.  In MC15, when I collapsed all the areas, the labels showed the analysis/calculation flow which is real nice. Is this functionality lost in prime? 

Hi,  I’m looking for help with a formatting issue in the footer of the attached document.As part of our design submission, we are including various calculations in the appendices and would like them to appear in an orderly manner. For referencing purposes, we’ve attempted to include the appendix number alongside the page number in the footer of each calculation (see attached example).Could you advise on how to align the formatting so that there is no visible misalignment between the appendix number and the page number? I am using Mathcad Prime 10.0.0.0 Kind regards,Iain

Hello,I’m trying to linearize this type of curve using the simplest possible function: I tried many kinds of fits, but none of them worked.Do you have any idea how to do that?thank you, Emilien

Hello All,I have attached MC-P11 sheets. How can I  extract the segment lengths values "L" out of last iterations of this following function. There are two conditions as you can see in subsequent calculations:                            1. For Element B in Compression, comp="B"2. For element C in compression, comp="C""L" values can be different or same depending on above conditions  and  segment lengths.Regards,Sam

Hello,I'm using Mathcad Prime 11.I'm trying to solve a differential equation with conditional logic (if) due to the presence of a diode in the circuit.The input values are defined, and in the worksheet, some graphs are already plotted (e.g., I_TEST, VL1N). I'm using Odesolve to compute the solution. Is this the correct approach?It doesn't work with the following error "Plot failed"Cou you help me? Thank you very much

I don't have a graphic calculator. I only have MathCAD 9.0.0.0. Is there a way to graph the following steps in MathCAD......or to solve for f another way. This is just an example problem. Once I learn how to do it, I can use it on my homework problem. Here's the full context of the example problem...Thanks,    Brent

Using the basic motor (DCPM) motor equation ...electrical and mechanical which have differential equations. I can solve the differential equations in a solve block. I want to create a sum squared error between the measured data and the model, and then using minerr to estimate the motor parameters. The measured data is Ia vs time and rotation speed vs time. But I cannot have two odesolve in one solve block. Can you help please... thanks.

Hi there Can you help to reach a graph merged to the classification I have I have this graph and I did a classification to the data in this graph ... what I need now is to merge the classification with the graph and make them obvious layers and then find the average in each layer like this By obvious layers I mean > a program wil be able to say from z1 to z50 >> it is a sand layer and the average Q in that layer is 10 MPa ( as an example) Is that possible ? Thank you in advance .. the sheet is attached
