Mathcad

Hello everyone, I have determined 12 points individually (2D). I want to plot a closed curve between these nodes and I want to have many nodes on this pattern?   I drew an example sketch and uploaded as adding.   Apart from this, I have serious lack of education on MathCad. I need a library that I can follow each sections. I  got sick of searching everything in Google. Could you suggest me a platform?

Hi folks,   the only reason I'm putting up with prime is that I do have a large data set and MC15 can't handle that many dots. In prime I noticed that once I've changed the trace colour, it became "uneditable"; i.e. I can't change neither colour nor line thickness anymore. Is it just me or a prime bug? and - does anybody know a workaround?   Raiko

Hi All,   Our company's default font is Arial Narrow.   1. First, there is no Arial Narrow font available in MathCAD. 2. Is there a way to install Arial Narrow font in MathCAD (for both math and text).   Can someone please advise a way to work around this? Thanks in advance.   Regards,   LS

is there any inbuilt function to synchronize all the array so that i will get something like (given picture"file name: output.png")?

I want to do a custom function that receives a file name, and reads a matrix of symbolics, and return this symbolic matrix do Mathcad.  For example, my file may contain the following 3x3 matrix:   a                        b+c8           k/e3 0                        5+f4            0 (6*a)/(b+c)        0                 1   numbers are numbers, symbols are k, a, e3, c8, etc.   Anyone knows how to do it?

Hello guys, I am stuck for two days about an issue. I have to create a solution matrix for the following two trigonometric functions. m*cos(a)+n*cos(b)=x m*sin(a)+n*sin(b)=y   0<a<180 , 0<b<180 m,n,x,y are constants. a,b are unidentified. How can I solve x,y as matrix solution?   I will trigger x,y values with FRAME, so at each X.i, Y.i values I have to calculate a,b degrees and draw lines. I am using MathCAD 15.I would really appreciate your help. Thanks in Advance!  

Good afternoon group friends, I am a beginner in Mathcad, and I am not able to finish a static problem, if you can help me, thank you very much.  

Hi everybody Im trying to determinate the maximun of  two values with different units, but Mathcad does not allow it.   t:=2m h:=5kg Max(t,h)= ?    Help me pls 🙂

Hello guys,   I had to use prime 5.0 today since I have a large data set to display. The chart tool is, apart from being slow and unyieldy, is usable. However, does anybody know whether it is possible to have a value that has been calculated in the worksheet automatically fill in the legend tab in the chart tool. I'd rather not have to fill it in manually as reaction times of said tool are unbelievable.   Raiko

Hi,      I need to solve this equation to get an expression for volume fraction, phi (x). For the given constants, phi (x) vs x should look similar to that in figure. Kindly check attachment. I tried to solve it symbolically but it keeps showing an error.   Regards

HI friends, I am looking to get the solution for a Tetha for a quatrics potential from these equations: (Reference: Classical Mechanics by Herbert Goldstein 1980 2nd ed.) I have a potential     V(r) = const / r^4.   Can anyone here help me with a MathCAD 15 Sheet, how to do it? Thanks Walter    

Good night channel friends, I'm formatting a sheet in mathcad prime 5, and the following happened: the equation got bigger than the sheet, I would like to introduce a line break in the equation, but the CTRL + Shift + Enter command does not work. The activation icon (Equation Break is erased all the time, as shown).

Attached are two Mathcad 15 M050 files.  The Test_SUBROUTINE worksheet works; however, Test_FUNCTION worksheet does not work.  I assume it is because a vector cannot have arguments?  I really want to use the Test_Function worksheet as a reference sheet in other programs.  Any help is appreciated.

Hello,   Is it possible to define custom units in Prime 5.0 Express?  I have a drop down in Math Formatting and unit is there and not greyed out. However, no matter how I try, I cannot change any variables to the unit format. So I started to think maybe this is not supported in the Express version.     Thanks,

Hi, im new to Mathcad and this forum.    Im doing a project at school about wire straighteners. Im trying to calculate the height to set the straightening bearings to get straight wire at the end of the straightening unit. i figured out the equation to do this but i want to plot the curvature and bending moment of the wire for a distance x. I dont really know how to do this im still in engineering school learning and not that good with Mathcad. I hope some of you could help me, it would really improve my project.    Example:     I know the position of each roll, and i know the equation for the bending moment depending on the total curvature giving to make the wire straight.    Included is a Mathcad file with a short explanation on how the equations are formulated. I have a bigger file with all the details but that will require a lot of translation for me. I also have some literature on wire straighteners if anybody is interested.    Sor

to all   I am doing a sanity check on something and would like to set an integral - see attached mcad 15 file but cannot remember for the life of me how to set up the integral calc (integration variable, etc!) Can anyone help me on this one? Thanks Regards

Anyone having trouble linking a user function with the user library in Prime 3.0? I can't even link the basic examples. I get an error message: External _CreateUserFunction not foundfrom the linker. It's definitely defined in mcaduser.h that I compiled with. It's like it wasn't exported from mcaduser.libAnyone else having this problem?

Attached is a little example of a problem I'm seeing - in simplified format only to demonstrate the issue.  Background - I'm doing a 2D finite difference problem and during setup mathcad slows down an unacceptable amount and I can't see why it should.    I tried it in 5.0 with no change.  On my machine the 'slow' program here takes about 5 seconds, while the 'fast' examples are instantaneous - as expected since there's no real calculation ongoing. I don't see why it should slow down like this.  I suspect it's recalculating the 'node' matrix over and over. Or possibly a bug. Anything I'm doing wrong?     4.0 and pdf attached.  Thanks,    

Hello all,   I'm new to Mathcad, I had the software installed just this morning.  I am having trouble getting my plot to display properly. I played around with my variables and it seems like Mathcad is unable to recognize the variable Cstar (please see the attached file). I tried moving the variable block around and replacing it with single value (in case it was my syntax that was off) but still could not get it to work.    I'd greatly appreciate any help and/or advice on how I should proceed. Thank you in advance! 

Hi,       I am trying to model the sedimentation of spherical colloidal suspensions. For that, I need to solve the differential equation (check image file). I am attaching the mathcad file and the original paper. What I want is to plot volume fraction (phi) as a function of height (x) at a certain time (t) (Something similar to figure 3 in the paper). I would greatly appreciate the help.   Regards    

Hello, I am new to Mathcad,I have been using PTC Mathcad Prime 5 since yesterday. I have a problem when I use solve and assume for this quadratic equation. All the variables have mm as unit. If I assume mm <> 0 then it works. The answer I am looking for is 233.41847464108950079 mm. Ps. If I put = it shows the good answer (my bad, I was too frustrated about the if and else thing to try), but why does it show if and else?  Thank you

Hello,   I have to find the last value from a vector which is bigger from 0, as in the attached example. How can it be determined?   Thank you, Otilia

We are currently using the network license model of MathCAD and wondering if there was a way a standard user could review who has the license checked out?

Hey all,I need some urgent help.I was working on a school project, opened the file this morning and edited some units only. Saved and closed the laptop. (I do not know if this is related or not but when I closed the laptop, it shut down, when it should just go to sleep). I turned on my laptop back on a few minutes later to continue working,  and am now getting an error saying :I opened the log file and noticed it is corrupt... I am attaching the file below. Is there a way to get around this? I have lots of important work on the document and I cannot afford to start over! Thank you 🙂 

Hi,   I'm trying to make a template that can be used for circuit analysing using Laplace transform. Here, we have a second order RC lowpass filter and I want to use an repetitive input signal. In V2(s) equation, where we have the input voltage I would like to use the f(s) input function or even better g(s) repetitive input function. In the file attached you can see that I have 3 plots: one with input voltage as a constant, where it works and the plot is ok, and another two using f(s) and g(s), where it returns this error "Replace complex values and NaNs by real numbers". What can be improved in order to use the repetitive s domain function?   Mathcad using is Prime 4 and you cand find attached a .pdf too.   Thanks.
