Mathcad

Can someone please help me to open one file, all others are ok but this one that i need is not possibile to open. Is it possibile to restore it or??

Hello all,   I am planning on making my Mathcad sheets more efficient and wanted the sheets to select by themselves from tables the properties of steel sections as shown in my screenshot. And recieve an output in my calculation sheet.   Unfortunately I have not come to a good solution. I managed to reference for example three different sheets with for 3 section types (each sheet has one table with all the section properties), but once Mathcad discovers the desired section in a row ( lets say row "x") it also goes into the following referenced sheets and reads the line x in all tables and gives me the output from the last sheet I referenced. How can I make Mathcad stop reading tables once it found the right table? Or do I have a completely wrong approach to it? Thank you very much already for your help, Joe

Hi,   I've heard, that there is a free version of mathcad (Mathcad Express). I downloaded the free version with the link provided under this video from CreoParametric: https://www.youtube.com/watch?v=JqLumZBXfv8   After installation I'm able to create new mathcad-worksheets, but it seems, that there is a very annoying watermark in the background (something like "Created with PTC Mathcad Express... For further information visit...."). Is this really the free version ? Its not very nice to work with it and it doesn't really make any sense to print out the sheets created.   Thanks, Maik

I am solving a system of odes with imposed discontinuites on the right hand side. I can do this by calling a solver up to the time of the discontinuity, imposing the jump condition, and then restarting the calculation (as in the attached worksheet). But I want to do this for a series of discontinuities. Since all the jumps are the same magnitude and occur at regular time intervals, it seemed like there should be a way to program it rather than doing it manually, but I could not see how to do it. Can anyone help?

How do you convert Mathcad 15 (.xmcd) to Mathcad Prime 5.0 (.mcdx). Do I need both versions of Mathcad?   My XMCD, MCD Converter button in Mathcad Prime 5.0 is greyed out.

Hi,   I've made the attached plot but I have 2 issues. 1. although it's plotting the 3 lines of X vector doesn't plot the 4th , that is the x=2 so that I have a rectangle. 2. although it's hiding the axis expressions the space is still captured for the plot  and I have to leave free all this space which doesn't look good at all.   Can anyone help please.   Thanks,

I'm struggling to understand why there are two different ways to make XY plots in Prime 7 - one under the Math tab and another under the Plots tab.  What problem does this solve?   More specifically, I'm having two problems:   1 - When I insert a plot using the Plots tab, I can't find a way to put a grid on the plot.  This is an incredibly basic thing, so I have to be missing something.   2 - When I insert a plot component using the Math tab, I can edit the plot properties.  However, I can't figure out how to save the edited version so that it updates the plots on my sheet.  It seems to only let me save it as a figure file.  I have to be missing something simple, but I can't find it.   Thanks to the community for your help as I try to figure out Prime.   Mark     

Hi, I build a DLL function and run well in visual studio debug and got the result as i want. But mathcad load into this dll and try to run this dll twice with different parameter. As below pictures, first, i load this dll twice with different parameter (INP_g_pow_acc) & (INP_g_pow_acc1), but got same result (this result is correspond to INP_g_pow_acc) second, i exchange the parameter (INP_g_pow_acc & INP_g_pow_acc1), also got same result (this result is correspond to INP_g_pow_acc1) Seem mathcad just load this dll once, how can mathcad run dll twice with different parameter?? Very thanks for your kindly support.        

Hi,   Anyone knows how to hide variables in plotting? I don't want to see the various x-y thanks,

Hello, Please see the attached Mathcad 15 file. I am doing incremental solution formulation to trace a nonlinear curve.  the only step that i am not sure about is how to plot the  incremental solution (blue curve). I appreciate any assistance!    Thanks, Sam

Hi, I am very new to mathcad and was wondering if anyone would be able to figure out why after using Prime 7's in-built xmcd converter, the output of the solve block in the attached files is very different - but only for the first row of the output rather than the whole thing (highlighted below) Thanks in advance.

It would be helpful

Hi,   I'm trying to find a variable and I've tried three ways of doing this. Please see attached. I used an If statement and then put it in a program. Unfortunately, I can't see what is the difference among these 3 but I get different results. My preferred option is the program but I can't find why it is wrong..   Could you please check:)   thanks, 

Thanks for the presentation presented by Ilia Novikov. The presentation was very informative for me.  Please share on the forum the Mathcad file presented at the webinar. Thanks.

Hi How do I achieve the above. I have attached Prime 7 file. Thanks.  

Does anyone have above that I could try with Prime 7?    Thanks

Hello all, I have defined a function in Mathcad (prime v6.0) to calculate elastic modulus of concrete with two parameters density (gama-c) and compressive strength (fc) as shown in the following photo. As you can also see from the photo, the function gives a different value and units to that if we evaluate the expression directly.

Hi Experts,   Below are my office Mathcad (with legal license) and OS (with legal license) information.     I searched "control(s)" in community, but I can not find final solution. Some posts were posted about 10 or even about 20 years ago...   The problems are that: 1. when I open the quicksheet "Controls and Automation" (Ibelieve you can find the quicksheet in mathcad folder, anyway i save as and upload it), the button does not work. see below screenshot   2. Another problem is that when I Insert -> control -> Push button (or other controls or Web control...), nothing apears. Also, Insert -> Data -> Table, nothing apears.      But my own home computer(Win 10 OS). Mathcad (Mathcad15, need check details) works well without above kind of problems. So for the compatibility, I need avoid to use controls. This is very inconvenience and make sheet to be lower leavel... I try to find solution for years from internet and F1 help. Bu

Hi guys,   anyone knows how can I change the resulting vector to not include the 0's? meaning to be just a 2x1 vector?   thanks,

I am looking for a function in MathCAD Prime that will give me the atomic or molecular weights of elements or molecules. There is a function in Excel called mw() where you add the name of an atom or molecule in quotes and it gives you the weight per mole. For example =mw("Li2CO3") produces 73.89138.   As a chemical engineer this would be a very useful function in MathCAD and frankly I'm surprized it isn't in the base functionality.   Can anyone suggest how one might try to implement this functionality?   Thank you in advance!   Mike McNamara, P.E.

Hi guys,   I'm pretty new in mathcad and I really need your help. I have a vector and I want to check each member of it, if it is negative or positive. If it is negative, I want to compare it with a value but if it is positive I want the program to stop. Please see attached   Cheers,

Hello, Attached is Mathcad 15 file. I don't know why i am getting two different results with matrix multiplication. Thanks, Sam

Hi everyone, I started Mathcad with Prime without knowing the all extra functionalities Mathcad 15 has. Please see the following screenshot. If I copy and paste Mathcad 15 lines and paste into the Word, result is perfect, everything is clear and it seems like vector image since I can resize it. If I copy and paste Prime lines, it is awful. I cannot put that in my report like that. Same result with rtf export. PDF export is better, but I have to include those in my report. So, I know this comment is made thousand times in this forum, but how PTC can think removing too many functionalities and features is a good idea? I mean almost everybody uses Mathcad to supplement reports. I would like to hear your user experience too. Do you only attach your report as PDF? Is there anyway to get the calculations to Word from Mathcad? (I know the answer, no.)  

Dear all I try to divide element matrices but when I use n=100 , program error.Do have any methods/solution to avoid this problem?Thank u
