Mathcad

Hi Guys,Does anyone know what are the minimum hardware requirements for running Mathcad licensing software?Currently running our licences off an old server with the fear that it may pack it in soon. Rather than purchasing a new you beaut PC we might try to get away with a very basic computer.Cheers,

I defined a user-defined function: However the variable after the equal remain undefined.Already I created similar functions. But, this one is giving me a hard time. Could someone help me please.MathCAD Prime 4.0

Hello,When I translate a Mathcad15 worksheet into a Mathcad Prime worksheet, it puts these red arrows and lines in there, which can be removed using the clear annotations command.What do these annotations mean? I don't want to simply clear them and ignore them if they are really important, and pointing to some problem or flaw

Hi All, I have a 4th order equation for an unknown parameter. The equation includes some constants whose number depends on the external setting. The parameter must be a positive real number. In the attachment, I listed two possible symbolic solutions k2_1 and k2_2. How can I set the if else condition correctly to achieve the following requirement?(1) if both k2_1 and k2_2 are real and positive, show both of them as the solution of k2(2) if only one of k2_1 and k2_2 is real and positive show this real number(3) if neither k2_1 or k2_2 can satisfy the positive real condition, show an error messageThank you!

What would be the best way to get a solution where  A  is the maximum.

Hi All,I am trying to get a skewed bell curve to represent a chemical in a reaction via an equation. This first bell curve will be subtracted from another skewed bell curve that represents a second chemical in the reaction. I have tried many equation types and have settled on the one that I am currently using. The trouble is that I cannot manipulate the equation variables enough to attain the configuration that is needed. Would you all inspect my equation and advise me on whether it can be edited to fit the Benchmark dots on the graph. Maybe another variable can be inserted into the equation? If, not, can you recommend a new equation? The curve slopes are not as critically important as the start, finish, and peak positions and values.As of now, the starting(blue) and finishing(cyan) points are good. It is the peak(green) that must move to the right without sacrificing the other positions.All help is very appreciated.Thank you,GaryMathcad 11

1. I meant to write nC/m^3 as a unit, nanoCoulomb per meter cubic.However mathcad considers it as something else (variable maybe?)All the calculations are correct.What should I do?2. I should put unit meter m on variable r2.But if I do that, the calculation goes wrong.any idea?

I'm trying to output mathcad results as excel or text files so I can imbed them in word, but it seems to me it only allows you to write dimensionless numbers? Is there a betterway to do what I am trying to do?eg I want a word document that says;"In conclusion, the Area is 2 in^2"where the number is calculated by mathcad. (the report is way too complex to do in mathcad alone, I need heading styles, tables of contents, image references, bibliographies etc. etc.)

How do you get horizontal and vertical alignment in Prime? This new grid does not do a very good job.

I try to find forces in this task. The Mathcad 15 sheet is in attach. Are equations in the Given-Find block right?What is the 8-th equation?

I have developed a simulation for GEV distribution by using log likelihood estimate. However, there are some errors on that coding.From that code, I expect every parameter (location, scale, and shape) should be come out in matrices not an integer. Hope someone can help me.Thank you.

   Hello Everyone.   From :     Similarly, the question is : How to transform from the Series to a Continued Fraction ?              Thanks in advance for your time and help.                       Best Regards. Message was edited by: Loi Le

   Hello Everyone,   From :          So the question is : Is it possible to create a program function to transform from the Series to a Continued Fraction ?                     Thanks in advance for your time and help.                            Best Regards. 

I have a small programm trying to split a matrix depending on the content in the rows. Now I'm using the folling algorithm:take the row as submatrix on the actual positionstack that on one of the two alternative matrizes depending on a conditionUnfortunately this has a very poor performance both time and memory wise.Assigning the rows via i,j to a new matrix seems to be better. Any ideas why?thanks

Has anyone experienced this before?  The variable I type in comes out as grey, or grey out, and when you try to use it in a formula, it does not work?My worksheet was working fine before, but when I tried to do some "experiementing" with trying to disable certain regions, or certain areas, I get this problem.  I am not sure how to turn it back.I did find a "cure" in creating a completely new file, tested it to see that the variable and formulas show up as solid black and worked.  I then copied the entireccontents of the "grey formula" file to the new one, and the problems seems to be resolved,Not sure what is happening.  Thanks for any feedback so I know how to resolve it later if it shows up again.Dan

Hello,I have a problem with odesolve function in my algorithm in mathcad 15. The puprose is to receive deflection (and deflection curve) of statically determinated beam. The only load is prestressed which generates bending moment. According to Clebsch method I'd like to solve this equation in my case: So I was trying with and without units (You can see it in my file) and I didn't get even one working solution. I'd like to ask You for an advice, because I'm trying to use this function for the first time and I've got no more ideas what should be changed here.Greetings Piotr

Hi,Could anybody help me with the error message in attached worksheet?All the bestPayman

The universal constant R is incorrect in mathcad 15. Is it so for you too?

Hi!I'm trying to solve the deflection of a beam with a constant load along it's length.I have a differential equation of 4th degree with four initial conditions.The moments in the bearings are zero and the deflections too.Now my question is: Why don't i get a solution with "Odesolve" in MP4 although i initialized all four conditions completely?Without Units, it works!The Error Message is: Any help will be appreciatedThank you.Best Regards, Volker

Do you know that we can use in Mathcad Prime? See the picture and try the Prime 3.1 attach! I have created this variable in Mathcad 11 thru Shift-Ctrl-j, opened in Mathcad 15 and convert into Prime. You can copy variable from my sheet, edit its and use in your Mathcad Prime chemical calculation!

I am trying to write a sheet for grad, div, and curl.I am finding that one symbol (rho) is considered as a constant instead of a variable.what should I do to rectify this?

I am doing some cost analysis in the attached sheet. I want to show visually the shapes of the three curves which if I plot each separately is easy to do. However, because the scales are so different I am struggling to find a way to show the shapes of the curves visually on one plot as they appear as straight lines when plotted together. Any tips?Andy

How do we write function to accomodate range of min and max .. in an interation function. Please see attached.I have list of Mw and Mmax values that i want to intergate all at once so that i can later use to plot a  graph. Please help.
