Hi I'm converting my Mathcad 15 sheets to Prime 7 and while making this change I have noted that Excel components in Prime are blurry, so it is difficult to see subscriptions in a table. (Example picture as attached) Is there some way to increase sharpness in these Excel components?   I also have another question about Prime. In Mathcad 15 it was possible to scroll down vectors, but with Prime the results are shown in impractical way. Is possible to get similar result visualization as could be used with Mathcad 15 (Picture as attached)?   Thanks for any advice.

Hello!   My iterative function "blows up" when calculating the displacement, velocity and acceleration due to a dynamic force. I do not understand why since from what I can see everything is correct. Any help is much appriciated and thanks in advance!   Regards Ture

I'm trying to find a copy of this support article from https://www.ptc.com/en/support/article/CS325855   The web page itself is blank.   Does anyone have it?

Hello, please forward it to the API development team. Please kindly send the interface   GetMatrixElement(RowIndex as integer, ColumnIndex as integer, Value as double) - Gets the matrix element in RowIndex, ColumnIndex with Value.   Change Value as double to support float64 or double because GOLang does not have a double data type, so I cannot get the Value of matrix.   Thank you very much. Thank you My problem is that I can get the matrix value in Python, but I can't get it in Golang. I suspect that the value I get must be a variable of type double. Python supports double, but Golang has no double, only float64. So ask the technical person who developed this interface to see if they can get the matrix value for a variable of type Float64. thank you

Hello, Attached is Mathcad 11 file. I also converted it from Mathcad 15 to Prime7(attached).  I did Nonlinear/ iterative solution in a manual way and another one with a small program at bottom of sheet. I have two load increments. In the manual way, it took two iterations per load increment to converge. When I compare the manual way to the little program: 1. Results matched in both methods for the first load increment , where you see green arrow and u=0.635. 2. Results didn't match for the second load increment. Manually, I got (u=1.613) after two iterations , but by the little program I got (u=1.599) where the red arrow is in the sheet ( please scroll down until you see the red arrow). Little program is shown at the bottom of sheet. For some reasons it shows a different number of iteration by the program.   I appreciate any assistance!   Thanks, Sam

Hi,    I'm not sure if my subject is correct. But I'm looking for function to show the formula or equation that was used in a variable especially if there are conditions that was used in the said variable. see example below. Variable Leh has 2 formulas that was conditioned based on the value of variable nv. if the first condition was satisfied, i want to display the formula instead of the result of the formula. Thank you  

I have the following problem. I have a vector containing 5 possible volt values and another vector containing 3 current values. I want to calculate in a solve block what the needed resistance is needed (according to ohm law). I can't figure out what is wrong with my solution.   Thanks 🙂

I saved my file and then can`t open. It says 'The file type is not supported. Log file is located .

I want to get old looking matrix formatted into table with columns as it used to happen in Mathcad 15 I am unsure how to do that in Mathcad Prime   Austin

Hi all, I need your help. I saved my mathcad file and then my computer crashed and now i cannot open it. It says 'The file type is not supported. Log file is located at C:\ProgramData\PTC\Mathcad Prime\Logs\MathcadPrime-Exception_20200506_163436.log Can i recovere it? This is very important! I use Mathcad Prime 5.0

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?
