Hello everyone, I have a new question for you that should be straightforward. I'm wondering how write a program to add additional rows to a matrix, where the values of the elements are calculated according to a formula using existing data within the matrix. The attached Excel file includes a tab with input for the ReadExcel function, as well as a tab showing the desired output by a writexcel function. Essentially, the matrix is a list of node point IDs with force vectors due to six load cases. Each node ID will have the same number of load cases and the input will be always sorted by LoadCase column. I would like to add new rows for each node ID, namely 7 OPEPOS and 8 OPENEG, using a specific formula which pulls its input from the existing data within the matrix. Input for the readexcel function:Desired output by the writexcel function:Rows 8, 9, 16 and 17 should be added by the formulas:FR is the force resultant.Just as a note, I have currently MathCAD Prime 8 and unfor

I have a long workshheet with a few  red or black two colour plots. When I save as PDF some of the red traces show as black. I have been very careful with Plot positions and spacing.  I have tried saving from the Math tab and the Document tab. Is there some official guidance?

I have attempted, but failed, to authorize my Mathcad 15.0 program. Is there anything that can be done to make this program work? If not, is it possible for me to upgrade to a current version and get credit for the Mathcad 15.0 that I already purchased?I am in urgent need of the use of this program. Anything that can be done to expedite getting this corrected would be appreciated.Thanks!

i would like to make FH4, FH3, FH2, FH1 the same value. only by changing alpha. i would be very gratfull if someone can help   

At the point when I work out segment properties for a bar, I for the most part run AutoCAD's MASSPROP order on the segment and afterward do any extra examination in MathCAD. I'm frequently doing composite pillars, radiates with custom shapes, and so on so I can't depend on wizardry equations for explicit shapes. There are a couple of properties that I haven't had the option to work out as effectively, for example, the torsional steady, distorting consistent, plastic segment modulus about plastic segment centroid, and monosymmetry steady. These are tracked down utilizing limited component examination. I have a python Programming interface composed by Robbie van Leeuwen called SECTIONPROPERTIES, and it's perfect yet my partners don't have the foggiest idea how to utilize Python. So with that unique situation, my inquiry is "How might I utilize MathCAD Prime to cut a part into discrete components and run a limited component examination or settle differential conditions o?

The trial version for Mathcad Prime 9.0.0.0 states that it has full functionality for 30 days. However, as I am using it, there are several functions that are unavailable to me. They even state "Note: This premium feature will be disabled after the 30-day, full functionality license expires. To use this and other premium features, please upgrade to a full license using the 'Upgrade' button. Specifically, I am trying to test out the excel embed functions within Prime as a long time Mathcad 15 user and this is not available to me to be able to do an evaluation. All buttons are greyed out and even converting old sheets over to Prime does not allow for the use of excel.

Dear all the reason of my posting is an failed conversion of a MathCAD 15 file/model to MathCAD Prime 7.0In particular this Model contains a quite complex differential equation, and after using the converter the new MathCAD Prime 7.0 model output an error on the command line which should start the solver (in this case it is the rkfixed, but the same error occurs also with other solvers. The red mark of the error is put on the "D" of the beforehand differential equation, the error report is (in german) "Ein_Aufrufziel_hat_einen_Ausnahmefehler_verursacht." This means something like "a call target has caused an exception error" (I do not know the exact error description in the english version).As MathCAD 15 is terminated by the supplier, we need a solution to further operate this MathCAD model. Attachment: The MathCAD 15 file and the MathCAD Prime 7.0 file after conversion. The said Differential equation ist given on Page 13...15 in MathCAD 15, on Page 16...18 in MathCAD Prime 7

Hi!Is there a way to make a filter based on comboboxes ? i.e. I want to be able to filter "Type" and "Version" so that the end result is a matrix i can plot I used vlookup to easily filter "Type", but not sure how i can incoorporate the "Version" filter? (I've attached my sheet, MCP 9) Thank you!  RegardsSNA    

Hello, Thank you for your time. I've recently downloaded MathCAD 6.0 and activated the 30-day trial. However, I was trying to open a .mcs file but failed. I've done my research and learned that this type of file (.mcs) was associated with MathCAD software, so it doesn't make sense if it couldn't work on .mcs files. Please let me know if there is any solutions. Looking forward to your reply.

A=Q/U*T should give m^2 , where Q= heat capacity in kW, U heat transfer coefficient W/m^2*K, T is temperature difference in K.  The area I am getting is in Kg^2. Why?  

I am unable to use Mathcad Prime.

Hi,I am having issues in acquiring license for the MathCAD 30 days trial. I have received warning message: "Program ID already expired."Please assist. Thank you.

Good morning, I spun my wheels on this for a while yesterday, and now I'm looking for help. The attached file was created in MathCAD Prime 8.0. In order for it to work, make sure that the csv file and the mathcad file are in the same directory. What it's supposed to do is accept a csv file with a specific structure and convert it into a vector of properties with MathCAD units. It was supposed to be a short program, but I'm running into a bug that I can't seem to work around gracefully.  When I have the READCSV(filename) function inside of a program, my output has no units, but when I have my READCSV function outside of the program, it works.  I want the READCSV function to work inside of the program so that I can call multiple csv files and combine the properties of each, otherwise the purpose of my overly-complicated data entry experiment is moot. Please help!  Thank you,Kevin

How can I delete locked areas in Mathcad 15? Is there any way to do that?  

Hi All,I am new to the forum.I am doing some case study in DOE,It will be useful if I get some DOE-Mechanical case studies sheet solved in Mathcad Prime 8 Thanks,RegardsGSVP   

Hello, I have a question. As you can see in attached picture, i want to create function if IL1 equal to IL2, but I want the equal to function to only consider 4 number of decimal places (ie: 0.6193). Is it possible? I use Mathcad Prime. Thank you 

I am getting a new computer which can be upgraded to Windows 11.  I did not take the subscription service to upgrade to Prime 7.  I would like to continue to use Mathcad 15 and Prime 6.  Does anyone have experience on installing Mathcad 15 and Prime 6 on Windows 11?  I know neither are certified for Windows 11. Regards,

Dear All, I am trying to write a program to return the only KP values when F is greater than 0.   

Dear All, I am trying to assign the back to the largest value matrix within the gap =6 back to the range, i.e. 1 to 6, 6 to 12 and 12 to 18 and so on .. What is a suitable program and looping to do compare and reassign the largest value back to the range of matrix.    

HiI want to calculate the maximum deflection of a structure subjected to bending. The deflection occurs within the buckling length, defined as the deflection within the points of inflection i.e. where M(z)=0. I have plotted the moment and the deflection in the attached file, but need further assistance finding the maximum deflection within the buckling length (see page 2 in the attached file).  Any help appreciated!   

Hello, I am new here, and would like to know if there is someone modeling optical fiber lasers using MC Prime 9.0.0.

Mathcad prime 8 Are the worksheets in the structural design library able to be downloaded or are they suuposed to only be pdf files for reference?  Are they free/how to buy if not?  

 This has affected me again.  This has been a recurring problem.  I responded to Mitch G. and fully explained my situation.  He provided NO HELP.  Just sent me to a website that was no help. My 10 year-old PC is showing signs of failing. I still have my original Product Code and MED-60602-CD-150_M050.zip file, as well as the unzipped files, plus my sales receipt indicating my license is perpetual for my academic version of MATHCAD 15.  I also have my original license file. Apparently, MATHCAD 15 cannot be re-installed with all my above original information without having to contact PTC; it will this be another painful process? I have been using MATHCAD since well before PTC took over.  I think I started with MATHCAD 3, definitely before MATHCAD 6.  After PTC took over MATHCAD, the licensing and installation were the most painful, convoluted processes I have ever encountered with newly purchased software. I guess I am out

Dears, I'm stuck on learning how to apply a real PDE problem. It is an application that I can observe in my daily life involving gas, the effect of a pressure wave caused by a transient in a gas pipeline when a valve is abruptly closed at the end of the pipeline. Reading several technical papers on this matter, many numerical simulations of fast transients have been performed to solve the partial differential equation for transient flows in horizontal gas pipelines. Dorao (2011) [1], like many authors, starts the discussion with this system of PDE:  I was thinking (naive?) that I could simply solve this using the PDE Solver, but after many trials and errors, I came to a halt. I´m stuck setting the initial conditions right for the solver:T0=-0s is during a steady state. Flow, velocity, and density all are the same for the length of pipe L, from L0 at the (inlet) and L1 (outlet), as this is before the transient.After this, the flow stops:T1=+0s is the outlet valve closed.

This does not work:Error message says "variable not defined". But this works:The intention was to add an entry to the matrix at the end.This is quite odd, experimenting I found this works without the "=" sign:
