Mathcad

Hi, Im trying to solve an ODE equation system for an adiabatic closed reactor. When I try to solve via ODESOLVE all variables keep as straigth lines.Thanks in advance!

Hello! I have installed the trial version of Mathcad Express Prime 7.0, but I can't use the conversion function XMSD, MSD to convert from the XMSD format. what could be the problem? And i don't understand, do I need to apply licensing for the trial version or not?

I am installing Mathcad Prime 7.0 in a new computer but it´s not working. I received the license file via email but still cannot activate the license. Need some help.

I have a matrix and i need to assign the first column as a second column in another matrix , can this be done without identifying each individual element? In the example above id like to be able to create matrix D without having to specify every element from matricies A and B . Hopefully with the output as per matrix C. Thanks ,  Ross 

to all, Attached is a 1st test of using mcad15 inverse Laplace. While I get something, is there a way of getting a “neater” response out of mcad15? For example mcad15 returns sqrt(wf^2) – why not wf ? I think one can end up getting imaginary numbers if one uses specific values ! I know some of the regular users are very handy at using Laplace operations so maybe I might get a few tips and/or tricks Thanks [correction: a square was missing!]

How do you uninstall MathCad?

Hi everyone. I'm trying to plot 2 lines and a circle in mathcad prime 4, in the form (x-x0)^2+(y-y0)^2=R^2. I have values for x0 and y0 and R, but I can't figure out how to plot it. Solving for y gives me complex numbers. x0 and y0 are defined values of some earlier calculations, so their value can change, so they are not "fixed" numbers.   Any simple way to do this? (Seems all the info on this I can find is pretty old, and I can't open example files and such...)      

This thread was broken off of this original topic thread.     BTW, does anyone know, why Primes symbolic can't solve this simple system of equations? The new symbolic in Prime 6 claims that no solution was found and the legacy one (muPad) runs quite long and then we see A similar useless result in MC15 which uses MuPad, too. The system can be easily solved by hand and we get Guess MC11 with Maple under the hood for symbolic does not show that problem of not being able to solve this system.      

Mathcad prime 7. Problems on Page 9 Answers not as expected. Probably issues on how I did the subscripts.     

 

I have only one Mathcad-sheet with ORIGIN not 0 or 1 See ORIGIN - PTC Community I have only one Mathcad-sheet with continue programming operator. I can show it! But we can creat this program without the continue operator. But with the continue operator it is nice, fine, прикольно! Do you have or do you seen a Mathcad-sheet with continue priogramming operator?

need a working programm version

Hi all, I am trying to figure out if it is (mathematically) possible to obtain a x(y) function via the following system with odesolve: dx/dy=F(x) Do you guys have a idea if it is possible in mathcad, and if so, how?

Greetings, im trying to program something that fills a matrix automatically, but you can choose wich rows and columns to make 0 instead. So far i can do it by hand, just setting what row and colum i want (fil=row), and adding extra conditions to the "if"  I tried to use a matrix instead, like row:=[1 2 3], so if i= any of those 3 values, it assign it 0, but it doesnt seem to work with a matrix, i wrote it something like "if i=fil1_i" (_i meaning subscript), but it doesnt compare it to the value on the matrix. Im working with Power Flow equations, in this part i need to do a 2x2 matrix each space being a Jacobian matrix. Im trying to automate it, because this is with 2 "bars" so matrix are 2x2, but when its something like 6 bars i dont want to do everything by hand 

It will be very useful if you help me.

As per this thread, same issue:   Hello, Did you have a fix on this issue? Facing same issue but no response from anyone and couldn't find this topic troubleshooting anywhere.

HiI'm converting Mathcad 15 sheets to Prime 7 and I noted thatsome division lines are very faint (but not all). Picture as attached. Is these some way to get a clear black division line to all formulas? Thanks for advice!

Hi, the "solution" shown below is obviously wrong. Any help is appreciated! 

ODEsolve issue.  is it possible for mathcad to solve an equation with odesolve for: dx/dy=f(x)  to obtain a x(y) function?  

Implement a function warning that (optionally) highlights a Math Region and displays a message when the user either hovers over or the region or clicks on it. The function would be akin to the existing function error except that, unlike the latter, warning would not halt worksheet evaluation.     It's something I've often felt would improve a function's usability.  It might also have proved useful for highlighting the effects of partial application (and thus mitigating the need to remove it on the grounds that it confused some users).    Here's a rough example of warning's potential use:     Zoom in to display     Warning and error history - just another thought ...     Maybe a function Notifications that presents a list of warnings and errors together with the identity of whatever raised the error/warning?  Mathcad Monads ...   Stuart

Hi Mathcad-Community,I am running into the following error not able to debug it. First I though, that I might have a unit mismatch but after rechecking, everything seems to be consisten so far. What is the cause for the error?

Hi. Please solve this.This is solving complex numbers
