Hi all i want to interpret a pass/fail criteria based on if the point of intersection is above or below the  x-y axis line i.e. for example this would be classed as a pass where the lines intersect below the loading envelop      thanks Ben  

Hi all i am trying to set a pass/fail criteria based on if the point of intersect is above or below the x-y axis plotted line, is there an easy intersect function that mathcad has? or a pass/fail region that can be defined ?   as shown above this would represent a pass as it is within the region below the limit of the Xt & Lt plotted line   thanks Ben 

Dear Community,   I am unable to solve a particular equation having a unknown value. After evaluating it is giving the same variable in answer. Any suggestions how to avoid this?    

Dear Community!I installed PTC Mathcad Express Prime 7.0.0.0. (30 days full version) 28 days ago. I used this program for my project (it is a 70-page Mathcad document). Yesterday I got PTC Mathcad Prime 5.0.0.0. from my school. Now I have the problem that I can’t open my document which doesn’t include any features from Mathcad 7. Is there any solution for this problem? If this problem can’t be solved than can you tell me how I can copy this from my Mathcad 7 document (I am still having the Mathcad 7 document and the Pdf)I am looking forward to your answers. (please excuse any language errors because I am still learning English)Yours,David

Hello,   Attached is a Mathcad 15 file. It is for incremental/ iterative solution using Newton-Raphson method to trace a nonlinear curve.  I am using another example that has a solution. It is enclosed in the sheet. 1. I am unable to plot the curve resulting from Newton-Raphson. 2. i don't know how to plot the graph "number of Iterations" vs. "Increment"  3. I don't know what " While 1" in the attached file mean. Both solutions are included in the attached file but i am not able to generate them.   Thanks, Sam

 

I was evaluating two functions with columns of a matrix. They plotted fine, but when I multiplied them, the result did not (got an error). It eventually dawned on me to convert to index form and that worked fine. Why is this? Example is at the end of the worksheet.

I tried to find the maximum of the real function (n*p) but I failed. I used maximize and minerr commands. Where did I go wrong? What does TOL and CTOL mean? Thanks!

Hi,   I have created the attached worksheet for rebar choosing but not sure how it can show the rebar area at the end.   I'm choosing the rebar size and i have the area for various distances. After this I'm choosing the pitch. Any idea how this could return back the As?   thanks,

When i want to define a variable by := I get the following error,An unhandled exception occurred on the dispatcher thread. See C:\ProgramData\PTC\Mathcad Prime\Logs\MathcadPrime_Exception_20201225_021742.log for more information. Prime will attempt to save any modified files and close.Please restart the application.What should I do?

I am using Prime 5 for a large file (50 pages) primarily consisting of program modules. The Prime 5 code breaks done every 15 minutes with this message: An Unhandled exception occurred. See C:\ProgramData\PTC\MathcadPrime\Logs\ MathcadPrime_Exception_29201225_174635.log for more information. Prime will attempt to save any modified files and close. Please restart the application. The corresponding information is not available because the directory \logs\etc. cannot be found. The error occurs during editing and during calculation. I use Prime 5  since several years on smaller files without similar problems. Has anybody experience with this problem?

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.
