Hello,   I am trying to solve a differential equation for a clamped Circular Kirchhoff-Love plate.   Why am I getting this error in my displacement function w(r)?    

Hi,   I am trying to run an equation in Mathcad 14 but to have it run through a loop from i=1 to i=29. I then want the output to be in an array form with each solution to the equation being output sequentially in the array.   e.g. put i=1 into the equation and run, output goes into row 1 of array put i=2 into the equation and run, output goes into row 2 of array   I have attached an image showing my manual method, where I have laboriously gone through and done the equation 29 times (only the first several are shown). The image also shows my attempt at streamlining the equation to iterate through all 29, but this only outputs the answer at i=29 (the last one).   Any help would be appreciated.

Hi. I have a problem with some lost work in a Mathcad dok. When i trying to open the file, there is a tekstbox saying - ''Some regions are corrupted and connot be opened''. Can someone help me i this situation? I attached the file.   Best regards.

...in one case returning a vector; in the other evaluating only the last entry in vthrow? The expressions  have the same form.

I cannot make to work the algorithm of the attached file containing Gauss-Seidel Operator for linear systems. Can someone give an advice, please? I attached it.

I am trying to set up a solution for a symbolic equation, but somehow the solution units are not working out correctly.  I have attached the worksheet and would appreciate any comments on what is wrong.  The result should be in feet, but as you can see, there are three variables that are not being handled correctly.   Also for some reason I get an error message that says "The contents of the attachment doesn't match its file type." Do I need to save back to an earlier version?   I am running MathCAD 15.0.

Dear All, How let Prime Solve Root of Equation by Matix ? Many thank.

Afternoon,Have a quick question that might be better suited to the community than opening a ticket. I'm looking to upgrade four of our MathCAD users from MathCAD Prime 2.0 to 3.0. My question is in regards to the license. In the past, I've installed MathCAD 15 & MathCAD Prime 3.0 for users, where you associate the later installation with the former's license file (point to).As for upgrading from 2.0 to 3.0, I've never attempted this yet. During installation, do I point to the existing license file (2.0)? Also, do I install 3.0 and uninstall 2.0 afterwards or is there an "upgrade" option? I've look througn most of the "FAQ" documents and small PDF articles and haven't been able to locate any concrete information.Thanks,Jordan

I am new to MathCAD and am doing a simple static force equilibrium analysis. My goal is to understand the best way to do this type of analysis so that I can then scale it to more complex problems. MathCAD document is attached (prepared in MathCAD Prime 3.0) and a scan of the sample problem that I’m working on is shown on the second page of the document.   I was able to get the correct result using Method-1 and Method-3 but I’m not able to get Method-2 to work. In Method-2 I’m attempting to make the resultant loads Bx and By (the variables I’m solving for) variables within a function called B. I’m then trying to call function B in the moment equilibrium equation to simplify the form of the equation. If I could get this approach (or something similar) to work it would be great because for more complex problems it would be very convenient to write equilibrium equations as a function of reaction load [B] where [B] represents Bxi + Byj + Bzk.   Also, as mentioned, Method-3 works b

Hi all,   I am trying to generate a plot of a function P(y), where the variable y is itself a previously defined function, y(L). I have defined L:=200,201..400 and the two functions, y(L) and P(y) but when I attempt to plot P(y), I get an error about the value not being a scalar or a vector.   Is there a trick to working with functions dependent upon other functions?   Thanks  

I want to create a matrix using a little program with Kronecker Delta (1 if i=j, 0 if not) however it does not work. Where is the mistake? Thanks!

When we have not a circle but a line we have a parabola! When we have a circle we have line (r=0), hyperbola and ellipse? Or?

We all know that the symbolic engine in Mathcad (mupad) is not state of the art and often is not capable to solve or simplify expression where other software succeeds. But this wrong result "1" is surprising nonetheless. Can anybody provide an explanation (other than it being a bug)?

Hi All. I m trying to model a circuit which is basically a CE amplifier.   I m not sure how to start. Can anyone please help?

Hello everyone,   I have the following matrices:   x = (15 -17)    y = (-6 20)   z = (55 -75)    I would like to combine them to form a new matrix such as,   A = (x y z)   I'm thinking (not sure if its right) A would turn up to be a 1x6 matrix.   A = (15 -17 -6 20 55 -75)   Then I would like to get the maximum absolute value of A which if everything is possible up to this point then the result would be 75.   Any suggestions?   Thanks!  

I am wondering then how to fix this new problem. I have fixed the error for the basic file, but now I want to express the heat transfer not knowing the wall temperature but rather knowing the ambient temperature. The equations are not too bad to solve, but I'm having issues with the solve block having too many arguments after I made the functions of the variable I wish to solve for. I would like to put my conditions in as a function and get the feedback for the correct outlet temperature (assuming the thermal gradient isn't too large that the wall temperature varies greatly in the z direction along the pipe axis).The issue is I would like to express the properties of any given substance as a function of temperature (or average temperature in most cases).The excel spreadsheet (minus updating the properties) gives a correct answer by iterating through. The user needs to press the buttons several times until all errors are zero.I know I can do this problem in excel or a programing languag

I found a problem with WRITEEXCEL.  Wondering if anyone has a workaround.  If I write output to Excel (let's say 1,2,3,4...20) it writes those 20 rows to excel.  Then, if I change my result to (1,2,3,4...10) it writes 10 rows.  However, in the excel file the data in rows 11-20 are still there from the previous result.  So I have 10 rows of good data and 10 unwanted rows.  If I use WRITECSV it overwrites the entire file and I only get the 10 I want.  So, I can use that but is there a way to fix it for WRITEEXCEL?  Is this a bug or a 'feature'?  Using prime 4.0.  Thanks.
