Mathcad

I'm attempting to deploy lmgrd and ptc_d on a linux (Centos 7) machine, and have provided my server's host id to PTC for a license. The host id in this case is the MAC address: 70-85-...redacted....the license file came to me with some parts missing, specifically __HOSTNAME__ and __PTCD_PATH__I have replaced __HOSTNAME__ with my server's correct name, and I have replaced __PTCD_PATH__ with a simple period (.) to indicate "current directory", and located all the files including the license all together in one place under /usr/local/mathcad.When I attempt to start the licence manager: ./lmgrd -c mathcad.lic it will not start, the error given from ptc_d is that the host id is incorrect. The license SERVER line has my correct MAC 70-85-...redacted.... but ptc_d is complaining it has "detected" a host id 06-00-00-00-00-00. None of the server's ethernet interfaces have a MAC address like this. I would be grateful for any assistance here!Precise error shown:

Hello, community! So far faced nonsymmetric matrix. Normally diagonalization of this kind matrices goes through transposed left and nontransposed right eigenvectors. With the command L=eigenvecs(A,"L") and R=eigenvecs(A,"R") we are supposed to get orthogonal eigen space. This functions do not provide orthogonality in some cases. But if restoring the eigenvectors by each eigenvalue, it is. Does anyone know if there is something special I'm missing about left-right eigenvectors commands?

question: In MathCad Prime 3.1, my first plot uses N-values. I want to overlay a second plot that uses M-values for visual comparison. I cannot enter the 2nd plot using its scale as Plotting Function wants to use 1st scale. How can I add two different scaled plots to the same plot image?

I have been looking at some of your post and learned a lot. I am new to mathcad 15 and i have come across a problem with units. I have a program which gives me a matrix and that matrix has different units. how do i assign the different units within that program

It doesn't allow me to fix and I don't know how am I supposed to fix it.  (it is strain, so, it is unitless, or in/in is also fine)

Hi  My problem is to plot angular velocity as function of time. I get the message "this variable is undefined. Check that the label is set correctly" for the variable t - well - it's a variable defined in the function? -  Tips would be much appreciated.

And why is my second equation doesn't work but it worked in the simpler line below?   Thank you very much!

Hi, I would like to know, what should I do to make the 3D graphics of Mathcad 15 identical to those of Prime? I attach the two files.

Hi,   I'm new to Mathcad, so i'm following some tutorials. However, I'm getting stuck with this basic one:   https://learningconnector.ptc.com/content/tut-162/plotting-data?isNew=false   I'm reproducing the exact same input in Mathcad 6.0, but it's not working for me. It's telling me that x needs to be a scalar or a matrix. See the attached screenshot.   Please note that it does work when I evaluate the x=1..10 function. However, that creates a messy vector in my sheet, which I would like to hide... Can I get the plot to work without evaluating this function?

Hello everyonean unusual and old mechanical problem. Unfortunately there is no animation.The parameters - however - are not the right ones to obtain oscillations.  After a lot of work - I can't even do the animation. I would be very happy if someone completed the job. Thank you very much.  

How to prepare the graph as per the attachment   version mathcad prime 3.1   Regards, Robert

I'm trying to create a unit label (done this thousands of times over 25 years) with, for example:       where MathCAD recognizes pA as a picoampere unit, but not fA as femtoamperes.... (gotta fix that, PTC)   Prime threw in a label distinction in the math menu tab.  However, applying the unit label does absolutely nothing, and fA remains unrecognized as a unit.  This sometimes works, and sometimes not... Anyone else have this problem?

I have a set of data (x and y coordinates) from excel (see top of attached file), and when excel didn't want to give me the function for the data, I had to use a website to get a working onw. I am now trying to work my way from the data to the function in Mathcad 15, but I cannot get expfit to work. The guess values is where it goes wrong (probably just confusing me). I have the working function and coefficients at the bottom of the attached file, everything else is trial and error. Can somebody help getting those coefficients from expfit? Thanks in advance!

hi,   i'm assuming this is a known issue, but i'm wondering what the status of this is. if you paste an image into matchad or mathcad prime, different things happen. prime seems much better at handling images, but i don't like prime. so i use classic mathcad. in classic mathcad, if you paste an image that is 8 inches wide, it looks ok. but if you save as pdf it looks terrible. so you have to paste in something much larger than 8 inches wide, then use the handles to shrink it down to 8 inches. if you save that as pdf it looks fine. however, in mathcad it looks terrible and blurry. you can barely see the image. in smath you can paste in an image very easily. if it's bigger than 8inches it easily and automatically is re-scaled to fit the page width. it also looks amazing. better than mathcad or prime. however, i don't care for smath. it would be great if classic mathcad could handle images much better than it currently does. what i do is create documentation where i place math symbol

I don't know if this has been noted before, but I managed (by accident) to suppress the display of a symbolic solve in M15 [Mathcad 15.0 (M030 [MC15_M030_20131216])]Does this work in other versions of Mathcad?Stuart

The solveblock for this mathcad sheet will not work and would appreciate if any one could tell me why. Many thanks. 

Hi. Iv been trying to solve this question using solve blocks for quite some time with no success. It would be great to receive some help if possible.

I'm trying to use on odesolve command in order to create variables allowing me to graph Time v height & acceleration v time of a parachutist falling from stratosphere but I can't figure out why the it can't solve. Is it the equations? or is there a certain order I have to insert the odesolve? Any guidance is appreciated thanks.

hola estimada red tal vez me puedan ayudar con ideas de como puede hacer esta sección de una columna en matcad prime   agradezco mucho su ayuda  gracia !!      

Hello, How can I fix this file in order that the multiple input to work with units? Thank you

Hi I'm having some problems in Mathcad 15 using Given/Find to solve 4 equations with 4 variables, but I can't get the results. It says: This variable is undefined. The symbolic result returned is too large to display, but it can be used in subsequent calculations if assigned to a function or variable. It's about quater way down the worksheet.   Please help, I's so frustrated and confused. It has never been this dead-locked before.

Hi, I`m trying to get tangent stiffness matrix of 6 nodes triangular finite element. Beginning part of code contains symbolic calculation and very simple operations such as getting one element of vector or transpose are very very slow. So I can`t to continue.Thanks in advance for any advice. File is attached.

Hello,  I have a chaotic graph with the x-axis ranging from 0 to 200 increments. I would like to increase the increments of the x-axis to 20000 without that affecting the graph shape. 

Hi everyone.   I have a little problem with an interpollation data. When i start to use cspline the program give return error "The elements in this vector must be in ascending order."   Mathcad 14. P.S. Sorry for bad english.
