  Hello Everyone, From:   How to Fill Surface the Blue Curve ?   Thanks in advance for your time and help.   Regards.

Hi, I am creating a calculation report in Mathcad Prime 9 and I was wondering if it's possible to create a cover page that would not have the header that the rest of the document has. So far, I have not succeeded therefore your help is more than welcome! ThanksRegards,Alex

Helloi have an equation. lets saybut if i have less arguments i want to do a different operation, lets say:(of course defining the expression like this will say that it was already previously defined)I dont want to create a new equation with different name.   how can I modify my original equation to understand that the missing argument is null  the closest i have reached is using an IF operator and checking if the other arguments are 0something likeif z = 0 and y = 0     return xif z = 0     return x * yelse     return x * y * z then I need to wrinte something like this --> F(5, 5, 0)if the ecuation is more complex i dont want to write 0 on the argument i would like just to writeF(5, 5) and the equation should understand that Z is missing so just do x * y hope you could help me  

Hello  Is there a way to get shown a the formula behind a value. For example: If i define value for "e" = ((250/2)-(250/3)) = 41,67 is there a way to show the formula when later in the dokument i want to use the value "e", but i want to show how it was determined? when i try to show it now it only shows e = 41,67? best regards AJ

HiI have tried to create a program that calculates a function for each value in the vector, but the result is not being saved for each loop. What am I doing wrong? Thanks for your help.   

Hello All, I am attempting to find the percentage deviation of the calculated output.However, in Mathcad Prime, the calculation using matrix indices is producing incorrect results.What could be causing this issue? In the attached screenshot, the output calculation in green font is correct and was done manually, while the output calculation in red font is incorrect and was done using the matrix indices formula.I have attached the .mcdx file with my calculations for your reference.I would greatly appreciate a quick resolution to this problem. Thanks in Advance.   

Solving ode's I have run into this error before: https://community.ptc.com/t5/Mathcad/Return-Value-of-this-function-must-match-the-problem-size/m-p/727295/highlight/true#M195799 I managed to get around it by switching solvers from Radau to BDF, but I still do not know what the message means and changing solvers does not work this time. As shown in the attached (MCAD 11 - converted from MCAD14) worksheet, the denominator of dv does get small but never reaches zero because of the damping factor eta (Increasing eta does help but does not eliminate the problem. and eta should by ~10^{-12} on physical grounds. Setting p0 = 0 in the denominator does eliminate the problem,  although I do not see why. So, it does seem like the denominator is the problem, but, if so, I would have expected to get a "calculation does not converge" message. Tried playing around with other parameters to no avail. Any comments or suggestions would be appreciated.

I am solving an ode. The calculation converges for some parameters but not for others. My problem is I cannot figure out why. There seem to be no obvious causes, e.g. like a denominator going to zero. I have looked at a number of other aspects without success. I am not mathematically adept enough to tease something out analytically, but maybe some one else is. If anyone has any insights or suggestions, I would appreciate it. I have attached a worksheet. It is MathCad 11. I know there are some others out there using legacy versions like me (still using MC14).  Also sometimes instead of the non-converging error message, mc flags the rhs of the ode and says "The return value of this function must match the problem size." What does this mean?

Hey everyone,I’m trying to recreate a Mathcad worksheet from a PDF file titled Shaft Bearing Speed. I’m using the exact same commands from the PDF to write it in my own worksheet, but I’m running into multiple errors and mistakes that I can't seem to understand.I’ve attached both the original PDF, my Mathcad worksheet, and error screenshots for reference. I’d really appreciate any help in figuring out where I might be going wrong. Thanks in advance. Below are the screenshots of my errors... PS: The excel component is in-active in my worksheet for god knows the reason & hence, I had to use an image there, but with a "Read Excel" command on top. I hope you don`t judge me on that... 

Hey everyone,I've been working with Mathcad Prime 10 for a couple of months now, and I recently came across something that has me stuck. I’ve tried searching for a solution in multiple ways but haven’t been able to figure it out.In the equation I’m working with (in reference to the attached image), there is a right-facing arrow above the expression: concat( num2str( d/mm ), "mm" )I’d like to understand what this operator is called, it`s function, and how to insert it in Mathcad Prime 10. Any insights or guidance would be greatly appreciated! — Srikar

Hello,I have just started using Mathcad Prime 10.Does Explicit work with min and max functions, or I am doing something wrong?Please see below example screenshot. I'm sorry but I cannot attach the full example as it is too big and it is work related.I get "The unit are not compatible" error. GSKID is an Output expression from an excel component.Bs is extracted from a matrix. I have turned on Units/Constants in Symbols   

 

Hello,How to fill the below area enclosed between y1(x), y2(x), y3(x), and y4(x), like below with purple?          

Hi Mathcad Community, I’m working on a problem involving a box cross-section. I need to plot the shear flow distribution q(y) along the height (y). The plot should be linear in the flanges and parabolic in the webs, but my current plot is a step function and doesn’t match the expected values. Can someone help me redefine q(y), and provide the correct Mathcad function to plot a continuous shear flow distribution?Thanks for your help! 

I want to present results in a table I created.But having the variable name showing when I want to display the results is really not convenient.Anyway around that other than hiding the name with a white box? I mean...It's Mathcad...  Not Paint... Thanks

Good Afternoon Community, Need some help with solve block with Find function. Please see attached. Thanks, Boyer  

So, recently Mathcad wouldn;t open, I deleted it, then installed again but this time changed the file location. Now, I can't open any worksheet, if I don't go in the app, Open, and then select the worksheeet. Also, the worksheet in the activity bar or its location doesn't show the Mathcad icon. What can I do to fix this problem?

hello everyone, let's see if you can help me. It turns out that I want to plot a root locus.It turns out that I have to solve the equation [1+ K G(s)* H(s)= 0] for each K.For a given K I can do it with solve: for example:G(s):=10/(s^2+2*s+10) and H(s):=5/(s+5) for a k:=3 gives me the following result.R:[-7.75;0.375-5.07i;0.375+5.07i]how do I get the same within a program by varying k by different values? 

I recently learned about the following problem, whose solution function u(t) requires determining:u´(t) = -u(t)/t + 1/(t^3+t), u(0) = 0I intentionally called this problem a riddle 😉 .Please answer in MC14-readable format.

Hi,I have an equation likeWhere Q(x) is some complicated complex function of x. This way f (or sol, if you prefer) is a function of x.I would like to make x a range so that I can plot f as a function of this range.Is it possible to do that?Thanks  

I have an array (numbers of rows - 1,  number of columns - can be different). Example: I enter a variable in mathcad d = [1 5 10 15] and i want this array to be displayed in my list as d = 1   d= 5 etc... Help please. Preferably in JS. Translated using Google Translate.

Mathcad Prime 7 I'm trying to find solution with solve block, but possibility to find result depends on "x" (would like to find) initial value. How to determine proper "x" initial value? I would like to use Mathcad for automation, but if it's not clear what initial value I must use, it will not be possible. Thank you!

HI team, please anyone help me to get 3D plot. I have attached a mathcad sheet. Thank you

I am developing a sheet to calculate section properties of steel sections using Mathcad Prime 10, however I find the integration gives zero value for web thickness less than a number for my specific example.  see below screenshot and attached file. The Ay gives correct area, however the Ax doesn't. I have tried different values for tw which gives a correct result when it is larger than a certain number. For example in the I section if changed to 30mm, the integral gives correct answer.  Appreciate any help please. 

I have a Prime calculation that takes days to run--it's a complicated integration.  If I halt the calculation using the "Stop All Calculations" function on the Calculation tab, save the sheet, then return to that sheet later and re-activate "Auto Calculation" I believe the calculation will continue from where it was halted, even if the file was closed and reopened.  My question is whether or not this halt/save/continue does in fact continue the calculation rather than restarting it.  If I select the "Calculate" option the sheet will definitely start over from the beginning, but that's not what I'm asking about.  I can't submit the sheet due to corporate limitations but the question is general enough someone should have worked it out by now.
