I have a Mathcad document along the lines of:r:=10mm---------Many equations using r and other variables.---------stress = 50 MPaIs there a way to find the value of r that gives the minimum stress without totally re-writing the document?I know this can be done relatively easily for discrete values of r by using a vector but I'd ideally like to do the equivalent of an Excel goal seek.
To allI am thinking about a possible mcad sheet for an hyperelastic material ie a rubber. Attached is a typical curve for such material.I would like to predict the displacment (of some quantity, maybe stress) knowing the total force to be applied. I am not sure so will be happy to be corrected but is this a non linear problem (gien the shape of the curve)?Known total force to the applieda (non-linear) relationship between say strain & stressFindThe final "state" once all the toal force is appliedI haven't got a clue where to start. Does the probleme require some kind of iterative solver?Am I overthinking the whole think?Any suggestion is welcomeThanksRegardsJXB
I am using Mathcad 15.0.0.436.I am also using an older file that was created in Mathcad 14 with minor modifications to some of the inputs.The file printed fine before I upgraded to 15.I have full page text blocks that wrap at the margin to create multiple lines of text.When I print the file out, some of the text 'disappears' past the right hand margin.I have tried changing margins, and changing printers, but to no avail. This also shows up likes this in the print preview screen.I am not using a speciatl text font (Normal, Arial 10), so am clueless as to why this is happening.I use this text technique a lot and it will be very burdensome to manually change every full-page text block so that it is not full page and also fits on the page.Is this a bug, or is there a fix for this?Thanks
I prefer to work with a black bacground. Anybody knows how to set default font color to white ( in MathCAD 14 ), please?
Hello All,My data has several peaks and I want to fit Gaussian function to each one to obtain the position of each peak's apex. Could you please let me have the idea how to do this? My program should find the peaks and fit the Gaussian to each one.Thank you very much in advance.Payman
Hello All,I am using Mathcad 14. Unfortunately the function "localmax" is not working with this version. Do you know how I can add this function?
I have installed mathcad prime 3.0 on my computer but I don't know how to download mathcad 15 with the license (I need to convert some of my files). Can anyone help me with this?
Hello All,I have two oscillating signals. I want to find the position where1) The signals maxima coincide with each other (the best match), 2) The signals minima coincide with each other (the best match), 3) One signal's max coincides with another signal's min.Such points are indicated on the attached graph. Would you please help me with programming this step? Thank you very much in advance.Payman
Would someone from confirm or correct my understanding of the missing features below, and let me know which have been reinstated on Prime 3.0?1. You can't change font size for math expressions.2. You can't wrap a math expression to a new line.3. You can't spell check.4. You can't print preview.5. You cant add title and axis labels to graphs.
HiCan I read results from another mathcad file?If yes HOW?Thanks
HiHow can I use if function when I have two statement shall be valid at the same time:For example:y=0 if x=5 and z=10y=1 otherwiseHow can I replace "and"?Thanks

Can anyone help on how to use the matrix (taken from an excel file) in the equations...?In the attached Mathcad file you can see that I need to evaluate the output power equation as a function of k (as highlighted in yellow in the last page).I need the matrix (L11, L22, k etc) to be used in the equation (for the variable k)...In short, I need to plot a graph Pout(k) vs k........ all the values indicated in the equation of Pout(k) must be taken from the matrix.. please help to get the plot
Some time ago, there was a problem with the use of "Given-Find" solve block (I can not find this theme in forum). In an attachment, you can find a document with a solution to this problem from the PTC's technical support.
Hello,on the left side of my mathcad sheet is a pdf copy past shots. on the right side i am trying to follow the same steps. please scroll down to the red arrow. i am not sure why the results on the right side does not match what is the screen shot on the left side for Ke1,Ke2,Ke3. the other two red arrows are below. Thanks!
This is as much a tutorial as a problem, I suppose. When I was teaching dynamics I would take a representative problem and "beat it to death" to illustrate not only the dynamic priciples but also how these problems can be worked efficently using Mathcad.
Hi all,I tried to use two equations to solve two unknowns, but it said cannot find answer because needing at least two arguments that is applied to 1.I don't understand what that means. I have attached the worksheet and looking forward to hearing your solutions.thanks
Hi, All --I am trying to use spherical harmonics to represent a surface in 3D. The worksheet calculates through without error, but the results are off by ~24 orders of magnitude (for 12th degree Legendre polynomials). I note also that the magnitude of the answer increases with the degree of the polynomials.Anybody have any ideas? Maybe there's a better way to approach this altogether?Thanks in advance.Matt
why it is not possible to work in Mathcad (Prime 2.0) with the Newton Noation? As an engineer, I often need a point over a letter. Typically, the mass flow is indicated by a dot above the m and the flow rate to a point on the V. Are there not many people who need such a thing? Does anyone know a viable workaround?

HiI use the match function to find a value in a vector. However, for some values the match function returns a matrix instead of a scalar, see picture. Why does this happen? What is the match function doing?
For some reason, the square root symbol works but raising to a power of 0.5 doesn't:Version: 15.0Mathcad doc attached.
Hello people,I use Mathcad for college, and its a very usefull program.About a week ago Tab "Math Formatting" is normal, but don't update sheet, see example:I Start a new, then Tab Math Formatting, and choose like in piccture.When i start make calculations, it never respect new Formatting. I already have "repair", "uninstall" and "install" again.One use is complex numbers, i choos to show in polar degrees, and it shows in rectangular, why?Anyone has the same problem and was able to fix it?Regards,Luis Lourenço,Portugal
Hi all,Could anyone help me find what problem within the calculation, To solve two variables using two equations, but it finally said there needs at least two arguments but is applied to 1, what's that mean?
