Mathcad

Hi - I just purchased MCAD Prime 8.0 with a subscription which is locked license.  I want to be able to run MCAD on a 2nd computer occasionally (laptop).  As i understand it there is no HOME USE license provision to allow 1 user to use license on 2 machines. I think these are my options: A)  I can transfer the license fairly quickly i think (once i get my basic PTC account upgraded).  That seems less pleasant as delays in receiving the .dat file would be incurred. B) It seems there is a "floating" license option that uses a Flexnet server running on the local network (preferably).   C) Buy a second license for that 2nd computer. Am I stuck with C?  Is B possible since I have already purchased a locked license (can i convert)? thanks,russ

Hello MathCAD People, I am working on a shaft redesign project, and I start out with trying to plot the deflection of a more simplified model. I write the momentum function in Macaulay’s method and think plotting a deflection curve using odesolve should be a fast way to figure out where the max deflection happens by solving the differential equation and the boundary conditions. However, the plot just ended up with part of the deflection curve and say the ode function has limited range. Can you guys help resolve the error and get Mathcad plot the full cure?I really appreciate if you can guide me through this problem, as I really need a math model to validate my simulation results. Thank you in advance. 

Given  Soln x=1 and x=-1 I have tried the solve box - the answer depends on the seed value.      Best approach to solve in Mathcad?  Thanks.

I am not able to locate any checkbox in prime as it used to be there in Mathcad 15 to compute for 0/0How can I have this checked?

I have a series of about 40 Mathcad files that I must open, calculate, and save in sequence to obtain a final result.  Any change in file inputs for one worksheet in the series, results in having to run the series of files forward again to obtain the new final result.  Is it possible to create a master Mathcad worksheet that will automate the task of opening, calculating, and saving the worksheets in sequence, so I will not have to do this in a manual manner?

Hi,I am new to this Mathcad prime earlier I use Mathcad 15, I am trying to solve this equation in the Mathcad prime, but I am not getting the value, I also searched on the net but didn't find any proper solution.Please help me to solve this issue.To find the vale of the (an) The file is attached

Hi guys I have issue with matrix multiplications.Please see the file and (hope) help me with it. Best regards Andrzej

As per this thread - same issue   Hi   Its my first post here and I have problem with conversion from M15 - Prime 7.0 attached file. Can you guys help me with it?   Andrew

Hi Everyone, I am sure I am not the first to ask but could not find any information on this issue. How can I have mathcad to show the matrix value after having the variable in combo box. Also, is there any option wherin prime will open all the worksheets in draft view? 

Hello, sorry if this isn't the correct place to post but please help me out. I have the following eqn. X:= a + b <= c + d = 0 How do I get X to be defined as the lesser of the two. I want it to be defined as C+D if it is smaller, Not 0 or 1.It is only returning 0 or 1 depending on if the statement is true or false.  

I want to add hand drawn circuit diagrams in a Mathcad worksheet using an HP tilt pen.Is this possible?

When setting up a Mathcad Prime 8 document which makes use of specified Input / Output parameters, I've noticed that while Input Parameters have their default alias in the designation list be the same as their name in the document (entirely sensible), Output Parameters default to having the name "out" and alias "out_x" with x counting up. Does anyone know of a way to make the default alias be the same as the name of the parameter similar to Inputs? Screenshots of my lovely Inputs and less lovely Outputs included below.  Thanks in advance.

MathCAD is changing or not recognizing the unit of measure. The answer would be 28000 MPa

I would like to transfer my fixed license to a new PC. I do not have a current support agreement/contract. Is this allowed under the terms of the license?

I am getting error units are not compatible for the said equations and not unable to figure out the way to solve it. Any help is appreciated 

Please provide me with a link for MathCAD Prime 5.0.0.0 (free version) I need this to access files within my company, thanks.

I'm wanting to generate spice models in MathCad Prime worksheets. The problem I'm having is I can't seem to find a way to substitute the value of a variable into a text block.I calculate some variables such as: Model_Name:="HDS10M"Nf=2.4Isf=1.86e-7 Then I want to create a text block that contains something like this. .model Model_Name diode(N=value(Nf) Is=value(Isf)... ) but I want this to be displayed in the worksheet so I can just copy and paste it into a text file to have a model.. .model HDS10M diode(N=2.4 Is=1.86e-7) This would be very useful when there are a bunch of parameters like in a FET model or in a subcircuit to eliminate opportunity for human error. Is there any way to do this? Best Regards,Chris

Good morning,  I am running some deeper simulations in P8 and noted that the CPU grind was pretty fast. I was surprised at this and ran a simple side-by-side with compiled C on a simple summation test.  I found that the slowdown ratio was only about x25.  In similar tests, I have found Python to be about x200 to x500.  I'd be interested to know how P8 has achieved this.  Perhaps the developers could comment.  Here is the C++ project   /* time example */ #include <stdio.h> /* printf */ #include <time.h> /* time_t, struct tm, difftime, time, mktime */ #include <iostream> double F_SUM() { double SUM = 0; for (long i = 0; i < 1000000000; i++) { SUM += i; } return SUM; } int main() { //clock_t clock(void) returns the number of clock ticks elapsed since the program was launched.To get the number of seconds used by the CPU you will need to divide by CLOCKS_PER_SEC clock_t t_STR; clock_t t_END; dou

Good morning,  I was going to post in the suggestions, but I do not have permissions.  I assume this has been discussed before but I wasn't able to locate.  Two big components missing in the programming toolbar are simple comments and unary operators.  CommentsI suggest the ability to add comments with a simple operator.  I have been doing the following for the last decade or so and it doesn't appear to incur CPU usage to any significant degree.  It would be nice if you could include an HTML link you can in Visual Studio.  This is what I do currently but it is clunky:Unary operatorsThis would be nice savings and improve readability.  Prefix and postfix operators would be ideal and save space.  I assume these could be made to run very fast.i++, i--++i, --ii+c, i-c, where c is a variableetc.Regards

I have a System of 2 ODEs and one Algebraic Equ By using rkfixed or rkadapt function I must have only 2 ODEs  Is it possible to have have ODEs and Algebraic Equations in rkfixed or rkadapt? With an integral?

I am unable to install my Mathcad Prime 7 licence. When I try to install it:From Mathcat Express I click on 1)Acquire License2) Select the products to install the license for:3) PTC Mathcad Prime 7.0.0.0I am getting the following answer:You have reached the maximum number of license requests available for your product typeDo I have to delete Prime Express and load a new Prime 7??????

Even providing all the inputs the lot will still not plot 

I am trying to convert old Mathcad files from Mathcad 14 to Mathcad Express Prime 8.0. Right now the convert button is greyed out. I believe it's because we don't have Mathcad 15, however we cannot get access to Mathcad 15. Is there any way to get a converter tool to convert our old files to Mathcad Express Prime or even get a copy of Mathcad 15?
