Does anyone know how to export string variables to text or CSV files withour quoation marks "" in MathCad Prime?This used to be easy in MathCad 15 using the Insert\Data\File Ouput.Thanks, colin

Hello All,   In the attached mathcad15, i'd like to automate the output "Z.summary"  for each steel thickness "ts" instead of doing each individually. On page 6, i had to create Z summary for each steel thickness ts=0.142, 0.150, .... How can i have it show for each steel thickness the corresponding Z.summary without having to individually putin the row number 0,1,..? i showed the results for Zsummary for t=0.142 and 0.150.   Thank you, Sam

I have a program that works (PPPWorks_12_19_2020) for solving a system of odes using Radau with the Jacobian (I am using this because the solutions have peaks which are slightly better resolved with this choice). I made what I thought was an innocuous change (PPPNoWork_12_19_2020) adding the equation dA=0 so that I could set the value of A in the initial conditions. Now the calculation for the Jacobian grinds away for a while, then crashes MathCad. What did I do wrong? Maybe I now have two many equations d(...)= 0 for setting parameters in the IC? Any suggestions?

Hi all,   I have a slight problem with my code. I have highlighted and explained the flow as well as i can. Please let me know if further clarification is required. The .mcd file is also attached for your reference. My question: When I look at the values of U_n and PTCU_n, the values seem to keep increasing indefinitely. In theory, PTCU_n should stabilize at 75% when tn_n reaches 6xRTC and not increase any further. I am not sure where I am going wrong.   Thoughts?   Any help is appreciated. Thank you in advance!        

Hi everybody,   I ask you because I don’t know any solution. I have some Data in the given Ex-celsheet. Interesting is the force F_S0_org and the according time t. This is the red plot in the diagram. I want to read out the time when the force F_S0_org is higher than the parameter GW for the first and for the last time. (For all three curves, to seperate them later) But my program gives me back all the the times. The problem is, that I don’t know how to realize an exit option for my if condition after it found the first time…. Something like break or continue. But it doesn’t do anything when I use these commands. You can see that in the diagram. The vertical blue lines are the times. So you can say that I want only the left and right side of the blue blocks.   Sorry for my bad english, I’m a german guy. Wish you a safe Christmas. 🙂 Thanks Paul.

Why someone is not correct? See lpease the picture and Prime 3 sheet in attach.

I try using Solve Block to find the solution of an equation by fixing "FS" to a constant value using the variables "alpha" and "w".  But it doesn't seem like working even it shows no error message.  Also, the unit for "alpha" supposed to be in "degrees".     The file is attached.  The first part of the worksheet calculate FS using the correct "alpha" and "w" values.  The solve block on 2nd page used the trial values of "alpha" and "w" to solve the equation.   Please advise.   Thanks,   Vincent

for learing it

Now in Prime too... Nice day!

Hello, how do i get the "CheckBrdg" yield the answer in a matrix format? please see attached sheet!   Thanks, Sam  

Mathcad Prime 3 doesn't work. Error "An Unhandle exceptionError "An unhandled exception occured in the dispatcher thread. See C:\ProgramData\PTC\Mathcad Prime\Logs\MathcadPrime_Exceptions_XXXXXXX_XXXXXX.log for more information." after launching Mathcad Prime

HelloI am having issues with the "find function". I am trying to solve for the reactions of the structure in the attached file. I've been wrestling with it for a while now and am finally asking for help.   Despite my units working out in the equations, MathCAD refuses to solve it. I am not sure what I am doing wrong.Some advice would be greatly appreciated.

Hi,   Good day.  Anyone could help me to make a tabulated graph similar to what I attached Material is aluminum  Moment of inertia is given 58.97 cm^4 I am using  Prime 6.0  Design pressure is given deflection criteria  L/200 Thank you.

I have problem with the command "if" in 3D solutions and graphs. In the sample you can find my mistake and please help what we can do with it.

Hi, I also know how to interchange more than two columns between two arrays, as shown in the attached file.   Thanks.

I am using Mathcad Prime 6.0 6.0.0.0Cannot get secondary Y axis on plot. When I try to "double-click the plot area to open the PTC Mathcad Chart application" nothing happens (i.e. no chart application shows up). In the Axes section of the menu bar there isn't anything that addresses adding secondary axes.

Hi, I need to adjust a Bessel function to this data. I was unable to make it and I can't discover the error. Can someone help me?

 

Hi There,I created my file in Mathcad 14 and need to continue my work In Mathcad prime, can you pls let me know how I can convert the file?

Hello Everyone.Given :inscribed circle of triangle ABC touches its 3 sides at A', B', C'. (see Figure)A'A'' is a altitude of triangle A'B'C'.Prove : C'B / C'A'' = B'C / B'A'' ( blue / green = red / pink )  Thanks in advance for your time and help.Regards.Loi.

In older versions of Mathcad (i.e. before Prime), I could change the default unit of each type independently, that is, I could set length to inches, force to kips, and mass to kg.   Is there any way to do this in Prime 4.0? I am well aware that I can change the display unit of an individual math region, but I need to be able to change the default display unit because I often work with matrices of mixed units. As such, I cannot change the display unit of such matrices, and I'm stuck with feet and pounds, and I'd really prefer to have inches and pounds.   Thanks, -Sean

Hi, guys im trying to solve this equation and get the value of coefficients (alpha1,2,3) and it doesn't work. Do you have and suggestions on how to solve this? I would like to use it in the future, so it should be parametric. I attached a screenshot and file. Thanks. https://imgur.com/2wQE0L0  

Hi Say I have an expression: Z(s):= c(s)[a(s)+b(s)]; where s is a variable When I evaluated them, they are not the same.    Z(s)=   The results is not the same as: c(s)[a(s)+b(s)]=   Please see attached for a better explanation. The bottom right row result is not the same as the bottom left result. Bottom right row is correct   I think it has to do with some kind of matrix errors   Thanks Rdliquid
