I am trying to plot fc_unc as a function of epsilonc, but mathcad keeps telling me tha epsilonc is undefined.

How to find a and b using these equations. . . .

Using Mathcad v11, I tried a simple interaction, to update variables according to the movement of time (t).Two points that have drawn me crazy: I guess the second does not have easy solution.In the picture below, I cannot really understand why the code SA1 does not work, and stops with error at Ai-1. I shall notice that  if I set t=1, it works. So the conditional "if" in SA1 seems ok. Can someone kindly explain what is the problem with t>1, while no problem is found in SA2 code?I made the error in another sheet - not in the one below - of setting my initial variables with the literal subscript (e.g. A.0) , even when the sbuscript is a number. I would like now to  "Replace" A.0, with a proper numerical subscript. But MC does not accept a paste of Math text into the Replace Window, for such subscript. Is there another way to write it in the Replace Window? Thanks.

I have a detailed spreadsheet for calculating pipe pressure drop and pump head requirements.Would love to be able to include this in a loop or be able to port in/out ranges of variables to generate system curves.I used to be able to do it in MathCad about 10 years ago.  I don't have my old sheets any longer.Anyone know of a way to get MathCad to handle a spreadsheet like this?

Hi I am a beginner in Mathcad Prime. I would like to make plot for under stated conditional function .Please help in this regard. V(t)= 5  for 0<t<5     =-5  for5<t<10It should be square wave plot with period 10. I mean after t=10 it should repeat itself.

Now that I have Mathcad Prime, I'm faced with the  problem of my literally thousands of worksheets done in MC14.I just did a search on the subject line above, but only got a thread in Russian, that seemed to be talking about going the other way.I'm assuming that an xmcd to mcdx converter must surely exist.  Where can I find it?  Thanks.

Hi, Today i started working in  mathcad prime 3.1 and i have got serious problem with units. Namely i calculate a value and i wanted to add a unit lm/W  -  for example Fi:=.....=145 lm/W and it showed me Fi:= ....= 145 (kg *m^2)/s^3*cd * lm/W but i would like to see only lm/W unit. Is that possible?

Hi all, if I have a long symbolic expression, that Mathcad returns the blank results, like the the coefficient of s^2 in this picture. If I want to show it, how can I get it? Thank you!

I use "Find" in a Solve Block in order to solve a system of non linear equations. I would like to change in auto-mode the guess values in order to solve the system for different values of the model parameters. How could I change the solution guess values for the solutions? Is for instance possible to include a solve block in the for loop of a code? Could you suggest a possible method?

Recently in a network I came across the following community with the interesting name - "PTC Community Garden" which is treated as "The Peachtree City Community Gardens". It is more about it here:Peachtree City Community Gardens - Home

Hi everyone,I have a problem solving an ODE. I want to calculate the deflection of a beam, but at the beginning I don't know the force and the force application Point. So I make a guess of it. With a good guess or with iterations (very much work) I can solve it. But because I have many situations like this, I want to do it automatically.In the attached file I have simplified the problem  and explained it more detailly.Thank you,Stephan

It is here (the 3-d message) New catenary problem, sorry.I have/had created a series of gif pictures and have/had created this animation by help one Internet site. (Sorry for English).Do you know other optimal way to create animation in Prime?

please

Following on from the thread Prime 3.1: Method for converting range variable to vector no longer works!, I thought an updated, ORIGIN-independent version of my vec function might be of some interest.The vec function converts its arguments into a vector, including nested arrays of arbitrary depth.   See Vectorization (mathematics) - Wikipedia, the free encyclopedia for further information on the vec function in linear algebraeApart from Prime's (<= v3.1) inability to accept a range definition as an argument, vec works in Mathcad 15 and Prime 3.1.Stuart

I downloaded a zip file from the PTC community from the following URL.        ·Finding the Shear Force and Bending Moment Along a... - PTC Community   After downloading and unzipping the file, I have a file extension of .mcdx (relations_between_distributed_load_shear_force_and_bending_moment.mcdx).  I tried to open this file in MathCAD however; the file fails to open.  How can I get this file to open?  I am using PTC MathCAD 15.  Should the extension be .xmcd?   Apperently the .mcdx files are for MathCAD Prime.  How can I convert MathCAD Prime files (.mcdx) into MathCAD 15 files (.xmcd).  I have tried simply changing the file extention but that did not work.   Regards, Thomas Henkel

Is it possible graphing inequalities in mathcad and shading an area of interest in the graph?Examplegraph these inequalities and shade the are that found at the interception pointsy<=3-(x/4)y<=6-xy>=1x>=2thank you!juan.

Hi all, I recently encounter an issue while writing my algorithm and have no clue how to resolve it. Can anyone here help me out?Please see the attached Algorithm. Appreciate if anyone here could advise. Thanks in advance. Cheers, ZQ 

Hi, everyone,I tried to program a fourier series of a step function,  using the complex form. Imitating the example code of the real series from the HELP folder, it succeeded.But when I wrote it in terms of my own perception, it failed.Could someone help me check where I did wrong? Please see the attachment.Thank you in advance!Shawn

Hi all, I want to use symbolic solver to convert a fourth order equation to the multiplication of two second order terms. All variables are real numbers. I defined the equation like this but Mathcad showed no solution for it. I attached the complete source code of Mathcad here. A big portion of this worksheet is the derivation of the left hand side of the equation, so you can simply ignore it (unless some of them are not executed by mathcad successfully). Would someone advise what is wrong with my solution? Can I put more restrictions in Mathcad, such as assume k0,k are real, to figure this out?Many thanks!

In Mathcad 15, if I want to convert a non-integer range variable to a vector, I can use several techniques, including this:However, in Prime 3.1 all I get is this:I want to complain!  Stuart

HiHow to solve for multiple variable with one condition?for example: how to solve this problem using mathcad program, I use mathcad prime 3.0if n>2m=x+y+zn=x+yp=x-y-zelsem=x*y*zn=x*yp=x*y/zI know how to solve one variable with multiple conditions using "if condition" in Mathcad. i.em=if n>2 then.........if else.........else............In this example I have accommodated few conditions for one variable. But in above program, there is one condition for few variables. and I don't want to use separate "if conditions" for each of the variable. I want to use one condition for each variable in one formula/block, if possible. Thanks Jahangir Hossain

Hi. I'm traying to use Prime. After a very good first impression, I must to say that may be it was premature. Have some few, and probably innocent questions:- How can add any (or all) operators and symbols ribbons elements to the kick access bar? Right click works with the Regions elements in the ribbon, but not for any other. Ribbon is not my enemy, but occupies to much screen space for my visual preferences.- Script components, where are you?- Object insertion, inside mcad worksheet (but not just for scripting)- Can't find how to add my own math style (in variables, units, function, etc.).- How can enter in debug mode?- Right click in math regions give nothing? There are no one contextual menu for math?- Where is the symbolic evaluation? Those hor or vert with or without lines insertions? (by diff given ... by integration gives ...).I can found more functionality in the hp prime calc or ti new calcs than in mcad prime.Thanks in advance.Alvaro.
