Mathcad

Please see attached Mathcad (prime 5)- Won't let me past the picture. So pic also attached.   Exceeds 2000 words or something  

Hello,   Need urgent help for this problem in Mathcad Prime 4.0 , What is the problem here ? The file is also attached in this post.     Thanks in advance.

Hi,  I am really new to Mathcad.  I have a problem to find a "d" variable in constraint with L as the dependent factor.  The problem is, I want to get "d" with range variables of L from 0 to 1000 mm. So I get range value of "d" based on the L inputs.    Could we do this by that way with solve block?  Appreciate your guy's help    

I am running the same function in Prime and Mathcad but get different results. See attached    

As resol for as equações para encontrar o valor de x e eu sou novo no mathCad Eu uso o MathCad Prime 5.

I am trying to plot a stress strain curve using a model but the strain values don't start from zero. wonder if anyone can look at the template attached. 

I need help solving these ODEs. File is attached and the ODEs to solve are at the bottom of the worksheet.       Thanks! Help is greatly appreciated.

Hello,   I am trying to work with my final solution but Mathcad is saying the variable is undefined even though it's being defined earlier. I have attached the file. Any help will be really appreciated.   Thank you, Faisal

any help would be appreciated with changes i need to make so the last formula on page 4 will calculate the individual values correctly.  

Hi,   I have been working on this equation and the worksheet works. Now I want to export rho_ms(w) and w to make a plot and be compared with the result from other program.     I have read about the vectorization process like in this https://community.ptc.com/t5/PTC-Mathcad/exporting-the-vector-of-f-x-y-function-into-matrix-or-table/m-p/569400 and follow one of the uploaded file. But I have this labeling issue. What I understand about this vectorization is we need to change our range variable into an indexed variable. what label should I put for that index i?if I use w(i), it is ok, but it comes back to a case of range variable, doesn't it? I tried with auto and variable, but still have error while one uploaded worksheet in the link above use auto and works. maybe i missunderstand something here. I attached the worksheet.I appreciate the help.  

Hi,   I need a help how to derive the graph . I attached all the reference and Mathcad  for your reference.    

Hi,   During integration with infinite upper bound, I found that the result makes me doubtful. Then I checked it by changing the infinite upper bound with a large enough number compare to other numbers in the equation. I got a more sensible result.   my question: 1. when should we not use this infinite bounds? 2. did I miss something here in my worksheet?    

Hello,   I need to find roots of a periodic equation by making initial guesses of x and assign the derived roots in "a". But, Mathcad is saying " the value must be a scalar". What does "scalar" in this case and how can I solve this?  I also need to sort "a" after assigning.   Thank you very much,   Faisal

I had to revert back to using freeware after hitting this snag with Prime 4.0... I don't understand what the difficulty is at step 5. Troubleshooting further down the page was successful after using new variables, so it seems to be a problem with my variables...   I even tried clearing the variables like my reference "Essential PTC Mathcad Prime 3.0" textbook suggests. Any help would be greatly appreciated in getting me back going... 

The … is for me an animations tools in first line! And for you? Tell us please!

Hello Everyone, How to correct the Pell(n) function ? ( for n = 181) Thanks in advance for your time and help. Regards.

Hi! I'm new to mathcad and trying to calculate some very simple equations containing symbolics and numerical elements. I know which answer to get, but simply can't make mathcad return the wanted result.   1/2 * cos(v) * p * L + 1/2 * sin(v) * p* L   I look for the result looking like: 0.67 * p * L   I tried searching for solutions for this but can't really find an answer, but it seems so simple that I can't possibly think that what I look for isn't possible?   Any chance there's an easy workaround?

Hi,          I am trying to solve the Kynch sedimentation process. For that, I need some help solving PDE with certain initial and boundary conditions. The objective is to get volume fraction (ϕ) in terms of height (z) and time (t). I am not really sure on how to go about doing this. It would be helpful if someone could take a look at it.   Thanks.

I am trying to solve a system of ode's that have gotten increasingly complex as I have added various effects. Everything was working ok until I made the last change (in attached worksheet, addition of the last term - in parentheses - in the expression for dp in the solve block). Now the worksheet does not even get past the solve block to the ode's. I dont get an error message. It just keeps calculating although I have left it for 30 minutes or so. The addition does not seem that complicated: the system is still linear for dv, etc. Did I do something wrong? Any advice?

Hi everyone,  I am new to Mathcad and I have 4 unknowns with 4 equations, each equations contains 2 unknowns, therefore all 4 equations are interlinked. See attachment for details.  My question is: I have used the 'solve' function to solve the equations simultaneously and am expecting the answers in a [4,1] matrix. However, that is not what Mathcad produced. Why is this happening and how should I solve it.    Thanks in advance.    kuay

  Hello, Everyone.   From :   ( image 1 )      Thanks in advance.

I'm probably doing something silly, but I can't seem to find it.  I set up a while loop but it always finishes on the 2nd iteration, when I know fully well it hasn't converged.  Prime 4.0 attached. Thanks!

In ancient times, there were some routines/functions on the old collab that allowed plotting of general text on plots by creating appropriate x-y vectors (or arrays) which plotted as the desired text. I searched my collection of various routines, but  didn't find any. If anyone has Mathcad 11 versions of these, I would appreciate their posting.   Thanks, Lou

Hi guys! I need your help again 🙂 MC15 file is attached.
