Mathcad

This is the new version of the worksheet "Nichols Chart.mxcd" (rudimentary) made some time ago with mathcad 14, imported  in mathcad prime 3.1, with the related changes.

Hi,Can someone please help me in finding the mistake in the attached solve block?Thanks,TDP

Hello,I'm trying to solve a "standard" 2D partial differential equation but the Pdesolve function gives the error: "The initial conditions are not consistent with the endpoints specified in the temporal range". I don't understand why.I also copied the Worksheet example on using Pdesolve into the file and it gives "Unknown error".I'm attaching the file in MC14.Thanks for the help.Gigi

Hi I have an error message saysHow could I deal with this error message. I added unit of temperature but it doesn't work.Any suggestions, please.

I want to determine parameters for function "N*(Sigma^m)=10^C" by using "genfit" built-in function in Mathcad. However, in the process of calculating an error occurs. Whether it is possible to bypass this error somehow? And maybe the input data not absolutely approach under this function ("N*(Sigma^m)=10^C"), but I need to know parameters for it.

Hi !,I trying to learn the programming methods at mathcad, for that I'm triyng to make a loop to classificate a Pressure Vessel according to the fluid,Pressure, Volume. But i cant get it, if any one could help me with that.

For the solution of one of tasks I work with the handbook by author Y. Murakami - "Stress intensity factors handbook", Vol 1. I try to deal with tabular values for a choice of correction coefficient "f_1"which enters a formula for coefficient of intensity factors "K_1". Correction coefficient (on the formula given in the reference book) depends only on the "alpha" variable which represents itself the relation of the geometrical sizes, however at a choice of tabular value for correction coefficient of "f_1" one more numerical scale appears there (values in it change from size 0.000 and to 0.010). What mean these values from 0.000-0.010? I looked at all first volume of this handbook, and also reference article [8], [25], [50], but didn't find a mention of it there about these values. There are any ideas? Perhaps I missed something.

Hello !Skimming through Mathcad Express I noticed that maximum number of lines for calculation is about ten per page.Is it possible to increase it without using characters too small ? (I don't remember for the moment if in prime there's zooming...)In older versions number of lines was around 20 and I am worrying about the no of pages for my longer worksheets after conversion/rewriting them in Mathcad Prime (MP).Are still there the pages on the right in MP ? They were useful, at least for me, as "notepad" area, for "recycling" expressions, tests,...Best regards,Liv

If I convert a version 15 document to Prime the plots come over with the vertical plot labels on the left hand side.Prime launches a new plot with the label on the right.Is there a way to move the labels to the left that I haven't found?

I am trying to set up the equations for the solution of a matrix displacement problem in structural analysis, i.e., F=KU, where F = force matrix {4X1}, K=stiffness matrix {4X4}, and U=displacement matrix {4X1}.  However, Mathcad will not accept the definition of these matrices with mixed units.  Do I have to define these matrices as unitless and track the results by hand?Thank you for your assistance.

Hello EveryoneI am new in Mathcad. I would like to plot "Bode Plot" from the given transfer function. I followed one of the attached reference ,but i stucked in between. Please help in this regard. Please tell me if any other simplest way exist to do so.

Hi, I have a system of differential equations to solve where I wish to vary an angle theta and plot responses in time waveform to show instabilities and a bifurcation diagram. I have used the same approach previously in a similar application that has solved successfully but for some reason theta is not recognized as a valid variable. Any help would be appreciated.ThanksRoss

Hi Everyone.I am trying to calculate the area between two cylinders, but i am not sure how to do this. Are there any of you guys that can help?Maybe if it is possible to plot the area, that would be great.The area i would like to calculate and plot:I have attached a mathcad file, where i have plotted the two cylinders.Thank you for your help.Kind regardsNiels.

Hi . Any one can help me to use the global definition in Mathcad prime. The situation is this. I have all the data in Exel sheet .  I only want to change the MATRIX INDEX as a variable. how can I get the assigned value base on the assigned matrix index ? I attached the exel file and the Mathcad prime for your reference.

Hi All, I have a two equations to solve and want to get the symbolic expressions of two variables. One of my variable k1 is a real number and assumed to be much larger than 1. Another variable Q6 can be either real number or have imaginary component.If no condition provided, it is a much higher order equations for k1 and Mathcad returned no solution. How can I set the conditions to "filter out" the unqualified solutions and get what I want? The worksheet is attached. Thank you!

Simple question here:Is there any way to return a row from a matrix in Mathcad 15?  Of course, there's a matrix column function, and there is a matrix row function in Prime, but I have been working in 15 for a while on a worksheet and would rather not re-create it (converter isn't recognizing 15 on my computer and therefore won't work).Thanks.

Estimados colegas del foro, tengo una consulta con respecto al uso de mathcad prime 3.1, espero me puedan ayudar.Tengo el siguiente problema definido:En la imagen he resuelto mi problema digitando cada elemento de la matriz "a", pero necesito definir la variable "a" de forma automática para muchos mas datos, hacerlo de forma manual sería tedioso, se puede hacer?

Why it not solved?

How do I move the two matrices from the right into the table (not manually type)?

Hi all,I am getting  error as no solution was found. Try changing the guess value TOL or CTOL.could someone help me.I attached my code below,

I have MathCad V.15, and theres one equation I can't solve. I've tried a simplified solution which works, but I can't figure whats wrong. Can you please help me?See attachments.Thank you.

Dear Mathcad ProfessorsI am a student. I am going to study Matcad S/W and I have a problem.   The problem is that I don't know to import data according to any data varidation.For example)Excel  A=250~500,   B= [ 1, 2, 3, 4, 5]A=100~250,   B= [ 1, 3, 5, 7, 9]A=0~100,   B= [ 0, 1, 2, 3, 4]If I need to import these data to Math-cad S/W acorroding to 'A' data variation  How can I do?I sincerly need to help. Thank you for reading my question

Hi, I have a question about PTC Mathcad Prime 3.1Is Mathcad Prime 3.1 available to use on Windows 10? Please let me know about it, Thanks,
