Mathcad

Any help gratefully received,I am attempting to plot an XY graph of a polynomial equation including x and y values, (e.g 4y+3x=10). cant find any help on any PTC guides and youtube drew a blank.completely out of ideas now, everything tried just throws a variety of red error boxes. many thanks in advance. BTW, using prime 8

Hello, I have a formula which defines water-pressure on a surface depending on depth and wavelength. To find the total force I have defined an integral. I want to find the depth beneath the water level where the resultant is located. I can do this manually by guessing values but I would like the program to solve this for me.  The only variable here is the depth for what I'm understanding by looking at my functions. Can someone help me understand what I'm missing in the attached calculation?  Regards/Tobias

Hello all, Does anyone have a suggestion for the following... I have a 170 page calculation, predominantly systems of linear equations, that has over 150 different inputs. What could be recommended as the best method for inputting the variables? I've tried utilising the excel component but it kept crashing.I've lumped them all into a matrix, this worked okay.I attempted to WRITEEXCEL them as they are being used elsewhere but it crashed the system.I am currently using loads of individual READEXCEL's but this is not ideal as it does not pick Excel variables (cell location cannot be moved). I'm thinking that a CSV intermediary between Excel and Prime might be best with use of some VBA, not sure. I'm in the slow process of re-writing the sheet so that logic can take care of some of it!  Thanks in advance.

How do I use the CWD path in WRITEEXCEL command   

Hola a todos, acabo de actualizar a la versión 8 prime y ahora no puedo encontrar el vector de respuestas.¿Tengo que usar el bloque de resolución obligado? personalmente me parece más cómodo la herramienta "solve, x"  Hi everyone, I just upgraded to 8 prime and now I can't find the response vector.Do I have to use the forced resolution block? I personally find the "solve, x" tool more comfortable  

Can you please tell how to solve a system of ode in prime ? Also a single ode with Laplace in mathcad prime 6?

After embedding excel component within worksheet when an input is provided the excel convert it to SI system if the unit system is set to USCS any suggestions?    

HelloI am trying to copy a matrix that is used to look up structural shapes from Prime 8 to Excel so I can update/add information, then copy-paste back into prime. Is this possible?

Hello,I would like to get a program in Mathcad that: given being a function with a certain number of parameters and a certain symbolic expression, f (p1, p2, p3, p4, ..., pn): = a certain symbolic expression that involves these parameters: p1, p2, p3, ... ,pn, to automatically obtain the following:1.  Symbolic calculation of: 2. Numerical calculation of:Given finally the numerical values ​​for the parameters: p1, p2, p3, ..., pn, calculate the numerical values ​​for the expressions of the derivatives from point 1.Example for the case with 3 variables: p1, p2, p3: 1. Symbolic calculation: 2. Numerical calculation The idea is that I want a Mathcad program that calculates automatically what I want regarding the two points above (point 1 and point 2), meaning to give me as output both the symbolic calculations and the numerical calculations, in the form of parameters, as shown for example in the example above (Sp1, Sp2, Sp3, Sp4, Sp5,

I am trying to use Odesolve. I think I am solving the same equation written in a slightly different way, but in the second way I am getting an error when I try to plot the solution.

I'm currently doing some calcs on the land-speed of a vehicle. From my other calcs, I obtained the wheel-motor's speed in RPMs, and the tire diameter. However, when attempting to obtain the speed from MPH, the calc seems way off. I did it by hand and used an online calculator. and they both gave the correct speed. What am I doing wrong, and how do I get the correct speed calc? 

Hi,I'm somewhat new to mathcad and trying to solve an equation with a solve block. (see attached)Tried several things, but without succes, I don't know if ti actually can work? perhaps with a for-while loop?The equation is quite straight forward with some forces and lengths, resulting in a summed moment, for which I would like to find a 0.  Can anybody help to achieve this or help me in the right direction? Kind regards, Casper

Dear all,I would like to extract the results from my Mathcad Prime run into Excel, but I’m not able to do so. I looked at the PTC community page but all suggestions given there do not work for me. I think it has to do with the way I run my calculations: I integrate in steps of 200 iterations and store intermediate result in a matrix and run the whole thing 'pmax' times (thus total number of iterations is 200 x pmax).I would like to extract the output from a certain row and column of matrix for different data points (1..pmax) and export this to Excel. For example, I would like to extract (Yt_ii)1,3 with ii := 1..pmax. Hope anyone can advise.

Is it possible to to index the summation for odd numbers in 15?

I have a table with a column of text and a column of associated numbers.  Is there a way to align the columns so they are left justified instead of centered and can you hide the " " needed to insert text? This is what I get when I add text, but if do separate text from values, then dont align 

Is it still possible to get legacy MathCad anywhere?

Hi! I'm trying to make a template for engineering calculation for hydraulic cylinder sizes and was wondering if there was a way to do the following: I have a function that spits out a number. I'd like it to be able to find the closest match to this from an array/matrix that I've already made. For example, lets say the calculation spits out a minimum necessary size of 3.054. The next available hydraulic cylinder sizes that would work is 3.25, then 3.5 then 3.75 then 4. I'd like it to spit out 3.25 as the answer. Thank you!

I am trying to solve a equation as provided in handbook but no matter if i use units or not I am not getting the correct result. I tried with applying units but somehow it gives me wrong solution 

Function f(x)=cos(x)  x: 0,0.1..2pi

Is there any way to copy a column of data from@ MS Excel and paste it into a Mathcad matrix?

I am unable to locate where the engineering references/books that were present in Mathcad 15 now in Mathcad Prime 8.0. Can someone point me in the right direction? Does my company need to add this as a service?

Hi Team,I know it is a long shot. But I hope there is a way to do this. Suppose I have 2 matrix with very different number of rows and columns, say A is M x N and B is L x K. How can I divide each element of A matrix with every element of B matrix and Have it in a form of Matrix.  I am trying few things with nested for loops but have had no luck yet.Thanks in advance,Kadhir 

Hello, I crashed PTC Prime 8 and the saved file is not able to be opened. The file is 93.8 KB so I think the work should be in there. If someone could help restore the file, I'd greatly appreciate it. - Rathet 

Some time I can just fix it by restart my computer.

I am trying to solve equation symbolically but when i try to evaluate it gives me error
