Mathcad

Im unable to open my Mathcad Prime 11.0.1.0 Student Edition. The app randomly crashed on me one day and when I tried opening it again, it does not do anything. No white screen, no error message, nothing happens. I've tried installing Mathcad Prime 10 but I am unable to use the files that I have in older editions. I've tried multiple things:- I've uninstalled and reinstalled.- Deleted Files and tried running it.- Tried running it using different compatibility modes.- Tried running it as an administrator.- Created Backup files.- Nothing worked.- Restarted computer Again, I'm not sure how to fix this. If you could please assist me with this issue, I would greatly appreciate it. Thank you.

Dear community, Can someone help me solve the integral of the following equation in Mathcad 7.0.0.0? Only J(x) and tau(x) vary with x, and the rest are constants.Thanks in advance

Dear ptc community, I am trying to plot a solved parameter of nonlinear equations (J) vs x (a variable that can range from 0 to 0.5. I have tried to plot it, but I got only a point rather than a continuous line plot. Can you please help me with it? I have attached my Mathcad  (7.0.0.0) file for your reference.Thanks in advance.Kind regards,Tadele

Hi there! I want to get one value interpolated from the parameter, obtained from the calculation routine.The goal is to perform interpolation of the curvature value Curvature (Alef, the second output's result) as a function of the bending moment value (Moment, the first output's result) from the given value of M_fact. By using the "linterp" function, I got stuck with the error message:"The elements in this vector must be in ascending order". After reviewing the relevant topic on the PTC forum, the only possible solution was to start the list of matrices at 1, yet my attempt to set ORIGIN:=1 hadn't worked. I use the Prime 10.0.0 version of the software. The file with the problem is attached. I'd be very appreciative of any assistance and advice regarding the issue. 

The Bad Idea Fairy was drunkenly wandering through my brain, stomping down the grass with his size 13 boots, singing off-key, scaring the squirrels, and littering the place with ... well, bad ideas.   However, whilst I was pretending to tidy up, I looked at one of those ideas and thought, "Hmm. Maybe he'd stolen that one from his twin brother, the Good Idea Fairy (you can't tell them apart, sometimes)?".   The idea? "Now that Mathcad 11 has introduced Python Scripting, maybe it's time to introduce a Mathcad equivalent of PEP 20?".   Instead of proposing a "Feature Request" or reporting a suspected bug, perhaps we could introduce an MEP (Mathcad Enhancement Proposal)?   Starting with:   MEP 00 – The Zen of Mathcad   1. >>> Range Variables Are Not Vectors <<<.2. Think in two dimensions for layout and data.3. Be like Zathras-- cover all possibilities. Zathras does not want other people being confoosed.4. Yesterday's friendly hard limits

I'm using MathCAD Prime 9.0.0.0. MathCAD is always forcing Units of Measure. Usually it'll choose appropriately based on the data going into it. However, sometimes it's wrong or uses weird units and won't allow me to override. A work around is I can not use units at all or I can put in a 2nd equation without units, but I shouldn't have to do that. One of the advantages to MathCAD is I can use multiple units in the same equation and MathCAD knows the difference. In this case...I want......but I get...I want......but I get... Thanks,      Brent

"Problem. A Poisson stream of requests arrives at a single-channel queuing system with loss. The time between the arrivals of two consecutive requests is distributed according to the law  the service time of requests is random and distributed according to the lawFind using the Monte Carlo method over a time period T=30 min: a) the number of served requests; b) the average service time of one request." If possible, please provide screenshots of the solution to the problem using Mathcad so that I can understand and clarify the essence of the solution..  

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 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

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.
