Mathcad

Is it one error in Prime (6). In Mathcad 15 all is OK - see please the attach!

I am pretty new to mathcad so working on and learning. Is it possible to get the result from programming in matrix form. I am trying but getting error. Can someone please help   Sam

Mathcad hangs when trying to work on embedded excel.

Hi everyone, I was just curious as to the various Mathcad 15 VBA based API functionalities. I am aware of the basic functionalities of buttons and utilising the solvers in other software, but I was wondering about the practicality of the following ideas: -Running a VBA macro for excel which will take excel values and generate a fresh Mathcad 15 worksheet with custom equations based on the excel input values (not just filling in inputs in a pre-existing Mathcad, a full from scratch build of a Mathcad document, with scratch built equations) e.g: Simple excel sheet showing the square root of each number from 1 - 100, the macro takes the 1-100 inputs and creates 100 equations in a fresh Mathcad 15 worksheet that square root's the input, speeding up the work of manually having to write out each equation. -A button that takes values from a pre-existing Mathcad worksheet and inputs them into a fresh excel sheet that is formatted via VBA functions encoded into the button. E.g: T

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?
