Mathcad

Hi,The partner sent me the mathcad 14/15. I try to converter to mathcad 8 prime but failed"This worksheet contains 4 locked collapsed areas. Locked collapsed areas are not supported in the current version of PTC Mathcad. You must unlock or expand areas before conversion."Please support to expand the areas or converter to Mathcad Prime 8 ThanksTuong    

It is the site of the article Игра в кубики или Кривая n-го порядка и m точек Readers can see animations and download Mathcad-sheets in replies PS Sorry - it must be not a question but a blog. But now we have not blogs here!   

Hello dear user, If it's possible can you provide the 3_2b Transformer Energization - Modeling in Mathcad file format or can I can change the file format? Thank you 🙂Original Topic link- https://community.ptc.com/t5/Mathcad/Transformer-Energization/m-p/901885#M208702

I want to make pdfs from a large amount of Mathcad 15.0.0 files since my license is expiring and I only want to work on Mathcad prime. How exactly does it work with the Mathcad 15 API or where do I get it from. Best RegardsFlamur Bytyqi  

Can you please help me converting this File

Hello everyone,I am attempting to perform the optimal transportation problema with simulated annealing, but I cannot do the initial approach correctly.Can anybody shed light on this procedure?CarlosRomero 

Does anyone know how to get Mathcad Prime 6 to return the Date and Time? (I know about the time(z) function, its not what I'm looking for. I want to create a 'timestamp' that I can export into Excel with the associated calculation results)

Hi all, This may be a silly question but I'm just getting started with Mathcad (Prime 9.0) and learning the ropes. In the attached spreadsheet I can't seem to use the solve function to find RB with predefined variables in the equation. If I manually input all the variables into the equation the solve function works but if I leave it as I have it, it does not. Am I doing something wrong or can you just not use pre-defined variables? Thanks,James

Hi, I have some questions about the attached file (questions are highlighted yellow on page 3 & 4). I'm trying to extract columns from my matrices Pz, Px, and My and combine them into new matrices, each with a Pz, Px, and My column, plus zero values for Py, Mx, and Mz. My first question: why do I lose my units when I convert the nested matrices Pz, Px, and My to regular matrices with the method I used? Second question - in order from easy to difficult: How do I create one matrix taking the first column from Pz, Px, and My? How to create three matrices with all columns extracted one by one? How to keep the number of matrices flexible in case columns in Px, Pz, and My are removed or added? I'd really like to understand how to do this for future projects as well. Below an image from Excel on what I'm trying to achieve.Thank you!   

I have a stiffness matrix where units within columns and rows are inconsistent. I tried to inverse the matrix but it said " The matrix element units are not compatible with this operation". How can I fix this? If possible. Or I just did this wrong. ps: I this question  a few years ago. The very same question. However, the solution is no longer working. Thank you for any inputs!   

HiWhat is the difference between unit  "ton" and "tonne" ? 

Hello all,I want to solve a formula symbolically according to a ratio.Here is a simple example:Does anyone have an idea how I can solve this?I use Mathcad Prime 9. GreetingsPhilip 

Hello,  I am trying to run this code and plot only "U" for the augmented matrix "R". However I am getting an error R has multiple definitions.  Please help! Thanks   

HiI am using Mathcad 9.0. I want to find the current I1 and put the value into the second equation so that I can represent the equation in I=U/Z from. But I can do it manually and not in Mathcad. I have attached my mathcad file as well as the picture, how I want to express my model.Please provide your valuable time!Regards,Waqas        

Hi, I'm currently having programming issues with converted mcxd files See attached screenshot. It's not reading PRN correctly. I have the file installed and using the read data file it finds the prn file it just won't populate the data. See attached screenshot.Any info would be greatly appreciated. The university used to use mathcad 14 and i believe when converting the file the si units are not populating either.Thanks,Josh             

Hi,I am trying to solve the following problem. I am new to pwrfit function. This is the first time trying to solve such a problem.1. Select a power fit in Mathcad to fit this data and model the metabolism rate as a function of the mass of the animal. Notice that pwrfit(vx, vy, vg) returns a vector containing the coefficients for a power curve of the form y(x)= axb+c that best approximates the data in vx and vy using guess values in vg.2. Determine the R2 value for this fit.3. Considering the fit is good, use the equation to predict the metabolism rate of a 500-kg manatee.  

Hello,On page 8 of the attached sheet, I am trying to build Mohr's circle. I dont know why the Ixymax, Ixymin,... on the plot are showing  in red boxes. Thanks,Sam  

Hi,I'm having problems with using MathCAD to extract the time at which the maximum value of a function happens. I've attached a file with the example. In the attached file, after some initial setup of parameters etc on page 1, on page two I define 2 ODEs in a solve block and solve them with ODESOLVE. This seems to work, and I have plotted the outputs in several graphs. They look as I expect. At some time I get a single peak produced on the graph of f(t). I want Mathcad to tell me at what t this peak happens. I've tried using Maximize, and this gives me incorrect answers for t. I've then tried differentiating f(t) and attempting to find the root that corresponds to the peak of f(t). This works for some sets of parameters and I thought I'd cracked it. But then I change one of the parameters slightly and root stops working, giving me the error message "The ODE solution is calculated over a limited range. Choose a value within this range or expand the range".&

I've got a 15 page document in Mathcad Prime 1.0. Items are strategically placed on the pages for readability and page breaks. However, when I save, close, and reload the file, my math and text regions seem to have all moved around; creating overlapping text regions and regions that flow over the page breaks.Anyone else seen this problem or have a tip on how to anchor these regions to the page between file opens?

Is it possible to copy part of one worksheet to clipboard and paste it in another worksheet?Seems to me it is not possible to do it like it's done for example in AutoCAD.      

Hello experts, I hope the question is in the right category. I haven't been able to find an answer in the community yet. A function should be passed as an element in a program [e.g. p(f):=II…]. This function can have a different number of its own elements [e.g. f(x1, x2, …)]. How can I pass the function to the program and how can I find out within the program how many elements the function has? Thanks for your help. SW: PTC Mathcad Prime 7.0.0.0

Hi everyone, I hope you are fine.I need to change the color of the result word, if it was safe to be green and red in case of unsafe.      

I need to plot the intersection and return it as a value.I have lines to show minimum and ideal operating temperatures but I would like to find the cut-off temps for each of the proposed AC-DCs. I have a graph that has the output derating so the line isn't a simple ab2+c so I have to use a function. I would like to know the maximum operating temperature of the multiple power supplies. Based on a Wdc1(Tempamb).  I tried using solve but this doesn't appear to work on functions. as the derating is not constant across the full operation range. see the example of the function I am using below. What is the best operation to achieve this? I have attached the worksheet for referenceI'm using MathCAD Prime 8
