Mathcad

Hello, I am working on a simply supported beam calculator. I have everything up and working but I am having trouble when it comes to determining the maximum of the displacement and it's corresponding x value.  In the collapsible area under the loads you can see I have the various displacement equations and to find the total displacement I sum them up. I then need to find where this value is a maximum but I don't know how to do it other than reading it off the graph.  Is there a more elegant way to determine the maximum so I can define a function for maximum displacement and corresponding x-location. I have attached the sheet for reference. Thanks,Callum 

I just installed Prime 8.0 I'm trying to convert xmcd files but the converter button is grayed out under the input/output tab. How can I convert these files?Thanks,Todd

Is it possible for me to mark a variable with a bar on top (see picture below) to indicate it’s a complex number? This is how I normally do it in WordMat:I understand that the bar is used for conjugation in Mathcad but it is how we are taught a complex numbers variable is displayed.

Hello I hope someone can help me, Im a student and through my school I have a license to Mathcad 7, but when i try to download it, I can only get Mathcad 8, does anyone know what i shall do?    

Mathcad 15.0Hello Can you please send me a link to the Mathcad 15.0 download on your website? I can not find it any more. There only seems to be a download for the prime 8.0 version.I am trying to download and use my Matcad 15.0 licence. My laptop got wiped recently and i lost access to it. I still have my disk and product code to re-instate but no disk drive on my machine.You helped me with this problem previously in 2019. many thanks and regards, John Dillon

I want to plot the adiabatic flame temperature of a mixture, given the excess air present but I don't know how to tell/write the program to find the value given the excess air. I'm using Coolprop's fluid properties libraries to get the enthalpy of the mixture and mathcad prime 7.

Hi everyone Does anyone know if the setting of using ORIGIN in string indexing is stored in any variable? A work around would be to use one of the string functions and check what it returns.  

Hi does anyone know this issues?

Over the years I used most versions of Mathsoft's Mathcad versions from the 1990's to 2017 (probably using Mathcad 14/15), when I retired.I have many legacy files from Mathcad 14/15 which I would like to convert using Mathcad Prime 8.0.However, after I installed and start the Prime 8.0 trial version, I selected the convert MCD/MCDX (which I had selected during installation) and loaded an old file into it (which was recognised as Mathcad 14/15), it is quickly flagged as 'No License' and conversion halts.Why is this? I no longer have access to older versions of Mathcad, which is why I hope to eventually purchase a full single user Prime 8.0 licenseso I can convert and continue using some if not all of my old files. I was hoping that the 15-day trial would give me a chance to see how successful conversion might be. Is there a solution?Please reply As soon as possible.

Hi allI am using Visual Basic for Application in Excel and am trying to pass an array of strings from Excel to Prime 8 through the API. I have managed to pass a matrix/array of numbers, but if I change the matrix content to strings, the OutputGetMatrixValue object fails with Errorcode = 7, suggesting "Matrix result is invalid." See Figure.png and below code. It appears not possible from the help documentation, see Figure2.png. Alternatively, I could convert the strings to unicode numbers, and then pass them to Excel through the below code, and then convert them back to strings. Or use a text file? Any suggestions for the easiest way forward? 'Get a matrix valueSet out2 = ws.OutputGetMatrixValue("out2")Dim q As VariantRowCount = out2.MatrixResult.RowscolCount = out2.MatrixResult.ColumnsReDim q(RowCount - 1, colCount - 1)For i = 0 To RowCount - 1For j = 0 To colCount - 1d = out2.MatrixResult.GetMatrixElement(i, j, dblhere)q(i, j) = dblhereDebug.Print "q(" & i & ","

I am in the process of writing an M050 worksheet, a patent disclosure, into Prime8. Quotient numerator and denominator are usually power series in root(s). In M050, simplify gives me a quotient in integral power of the complex variable, (s). Nothing seems to work in Prime8. This is so basic; it is a nuisance. I must be doing something wrong.

Does anyone know how to turn off the green outline that appears around duplicate variables in Prime 8.0? It even occurs around subsequent members of an array, which are technically not the same variable. Please see the attached screen shot. The green outline didn't exist in Prime 7.0 but suddenly showed up in Prime 8.0. I would like to get rid of it since it doesn't appear very professional in a printout. 

HI i dont know who i cant convert the file from xmcd to mcdx. can some kind soul help me to convert it ?

Hello do anyone have a work around for the following problem, i am trying to multiply the terms within Tidx by Phi and b, of which i get the correct result (when undefined). when i try to define that to put into another equation it pull through an error.   Sheet attached thank you
