Mathcad

Hello all,I'm using Mathcad Prime 7.0.0.0 and during calculations I get warning message as in title. I have PC with 16GB RAM and when I monitor task manager Mathcad doesn't reach top border of available memory. There is still about 5GB free RAM. Other components as CPU ect. also doesn't work at full performance...so I don't know where is problem. I know that this topic was touched previously but that answers not fit to my issue. Thank you in advance

I'm fairly new to the use of arrays and matrices in general. I'm in the crane design industry and modern codes require multiple load combinations to be analysed in structural calculations simultaneously. Codes then often pose choices based on things like stress ratios. For example, in it's simplest form, a different set of rules are required if a stress is in compression rather than in tension. I need the ability to automatically differentiate between these stresses, and the correct rules are applied for each load combination. Sometimes these problems may use array sizes in the hundreds. I've attached a very basic programme. My desired outcome is a single n x 1 array. What I tend to get is an array of nested arrays. I've played around and found that if I were to transpose this and turn the nested array into a single clean matrix, use the diagonal function, then this would give me what I need. I have no idea how to do this though. Help would be greatly appreciated.

I defined a function of x and y and plotted it. Later I am calculating matrix values for the function and trying to create a second function to fit the points. My belief was it should result in the first function but the second function deviated from first by large margin. How to rectify this?   

Hi, I'm trying to input this equation into mathcad, but I keep coming into the problem of incompatible units. Thanks for the help. This is also my first time exploring physics so it may equally be my fault. The equation is in the image attached.   

Anyone can help me reverse this program? This program contains the lower left side triangle to be 0, and I want the program to run on the opposite side on the upper right to be 0. My program does not seem to be working properly. If anyone can help me reverse "0" in the matrix, that would be a great help in my studies.  Thank you.

I am using Mathcad Prime 6.0 6.0.0.0Any chance Mathcad will support MathML in the near future?I would need this support in order to copy formulas from Mathcad to Adobe Framemaker vice versa.

I'm trying to use bvalfit to turn a boundary value problem into an initial value problem in Prime 7. I can find nowhere on the internet any resource that explains how to properly use bvalfit, and my current attempts are failing. Does anyone on this forum know how to use bvalfit?  See my sheet below.  Can someone please tell me what's wrong with my sheet? Thank you! For the record, yes I know this is an easy DE to solve. The point of this exercise is to get bvalfit working so that I can expand the application to other equations and standardize it in my worksheets.

To all I haven’t got a mcad 15 worksheet yet working on it while I am reading a couple of things on the matter – please bear with me and will attach soon   Is there any way of plotting a gyroid in mcad15? Looking at the ebook bout the ‘amazing picture in mathcad’ looks like it ought to be simple.   I am looking at the equation (see links below) for such shape and look straightforward but once again plotting 3D stuff in mcad is proving a pain.   0=sin(x)*cos(y)+sin(y)*cos(z)+sin(z)*cos(x)   Is anyone able to point me in the right direction?   Thanks   @ttokoro  is must be your kind of things    https://soulofmathematics.com/index.php/gyroid/ https://plus.maths.org/content/meet-gyroid

A simple problem wich worked fin in Prime 6 and doesnt in Prime 7.In the first line, a simple equation is solved (it's a linear equation!) - all works fine ...Then some constants where defined and a equation of the same type is to be solved => won't work, after a very long time there is some message, that there is not enough memory (again, to solve a linear equation!!).If one first calculates the left side of the equation, it works ....Whats wrong here? Prime error or mine .....  

Hello. i am trying to paste an equation i wrote in microsoft office (word) into ptc to calculate it for me.when i press Ctrl + V it pastes the equation with comma marks and they can't be deleted. what should i do ?

Would love help with this.  I've defined my function, inserted a table of values, and am expecting results in a vector format. HELP!!

I want to use Mathcad 6.0 to create a color-coded mesh surface plot of a hemispherical dome whose height ranges between 0 and 1.0 as defined by the function cos(πx/2a), 0 ≤ x ≤ a, with a = 300. The surface is “swept out” by taking this curve [plotted along the x axis] and rotating it a full 360 degrees about x= 0.  

Hi,Following my previous thread, I can successfully pass data from Excel to Mathcad, calculate, and then take the outputs back to Excel. Thank you @terryhendicott  !!! This is a summary of the code I am using.- Get inputs, Aliases, units from Excel.- Open Prime and worksheet.- Get Prime Input Aliases.- Loop through each Prime Input Alias and match them with Excel Aliases. If there is a match, add the corresponding value and units to Prime.- Calculate- Obtain Prime output as a matrix.- Loop through each Output element, store its value and send the element back to Excel.  This is the weird part that I can't figure it out. If the program runs by clicking the ActiveX Command Button, the Outputs are not added to the Excel.If the program runs in VBA and there are break stops, the program adds the Outputs to Excel as intended. The minimum number of break stops seems to be two. One after the I get the Outputs and one after the loops that moves the Output

Hello everyone. I just wanted to share some animations created using mathcad, I think they are great! It is about aircraft design, and it shows the aircraft performing some flight maneuvers, all inside mathcad using the 2D and 3D plots. youtube links:https://www.youtube.com/watch?v=7EQt2PT9Tighttps://www.youtube.com/watch?v=RdfJoxDi4qohttps://www.youtube.com/watch?v=fmUko9sFgGE Regards, Guilherme

Hello everyone!How do I embed an animation in a Mathcad 15 worksheet? Thank you!

Dear all I noticed the Caching Referenced Worksheets is not update until open and save.An ExampleFile A: is input fileFile B: is calculating file and never open that included (Variable A to Z and WRITTEXT .. ). File A is Referenced Worksheets of  File B.File C: is Result file. File B is Referenced Worksheets of  File C.I try to change File A and save . and open File C but not updated of Calculation. Until  Open File B calculate and Save it will work.Any Solution for Update File C without Open and Save File B?Best regardSPRSTRUCTUR

Hi, I managed to pass variables from Excel to Prime 7 and then back to Excel using Visual Basic. The code works as intended. Here is the code Private Sub CommandButton2_Click() Dim a, b, c As Integer Dim RowNum As Integer Dim Path As String Dim MC As Ptc_MathcadPrime_Automation.Application Dim WS As Ptc_MathcadPrime_Automation.Worksheet Path = CurDir & "\" & ActiveSheet.Range("J4").Value a = ActiveSheet.Range("C2").Value b = ActiveSheet.Range("C3").Value c = ActiveSheet.Range("C4").Value Set MC = CreateObject("MathcadPrime.Application") MC.Visible = True Set WS = MC.Open(Path) WS.SetRealValue "a", a, ActiveSheet.Range("D2").Value WS.SetRealValue "b", b, ActiveSheet.Range("D3").Value WS.SetRealValue "c", c, ActiveSheet.Range("D4").Value WS.Synchronize Set RawOut = WS.OutputGetRealValue("out") ActiveSheet.Range("C7").Value = RawOut.RealResult ActiveSheet.Range("D7").Value = RawOut.Units End Sub The issue arises when I try to pass multiple variables (100+)

The file is from Mathsoft MathCad, but I want to run it in the new PTC MathCad what is the solution please answer ASAP. 

This is what I found at the bottom of my desk drawer. Many do not even know what it is called and what it is for. And most importantly, all the instruments are intact and the leads stick out! This photo, of course, should be in the Creo section. But, I'm sure, and users of MathCAD will appreciate this tool, which often lay near the slide rule - Mathcad.  

My English barometer, bought all the way in Greenwich, Mathcad and WaterSteamPro show that in Moscow water is now boiling at a temperature 2.3 degrees lower than at normal pressure. So eggs, soup, pasta, etc. need to be cooked longer!Reminds me of Mark Twain.“Our troubles are over; so people could rest, and I finally had the opportunity to pay attention to the scientific side of the expedition. First of all, I wanted to determine the height of the place where we were by means of a barometer, but, unfortunately, I did not get any results. I knew from my scientific readings that either the thermometer or the barometer had to be boiled to take a reading. Which of the two - I probably did not know and therefore decided to boil both.Still got no results. Having examined both instruments, I saw that they were completely damaged: the barometer had only one copper needle, and a lump of mercury dangled in the thermometer ball ... I found another barometer; it was brand new and very good. I boil

Hi, I have just started using Prime 7 instead of Mathcad 15 and have to convert all my files. The issue is after solving a system of equations, the solutions I get are part of the solution vector I guess. I can perform calculations but cannot plot due to the error mentioned in the title. I have seen similar topics here, but I cannot find a way to solve my issue. I figure it is simple and straightforward. The fileis attached. Thanks in advance.Ali 

Each of us loves to dream. A person dreams that he has become the richest person on earth and can afford this or that. Another dreams that he would become the president of the United States or Russia and would do this or that.My dreams are more modest.My dream is that PTC will finally be smart enough to make Mathcad a free program. Not only Express. but full version of Mathcad 15 and Prime. At the same time, I am confident that PTC's earnings will grow at the same time. Why? Explainer!Those using Matcad for STEM education will get to know Creo, etc., and then move on to this project. The bottom line! By making Matcad free, PTC will generate more revenue.

Hello. I solved symbolically two equations by means of vector form (file attached, Chapter 3).I took the expression of y1(x) and added to the expression of y2(x) and then equated everything to zero.Is there any compact form of solving these equations in Mathcad? Solve block doesn't seems to work.My solution looks messy. Any feedback will be appreciated. Best regards,Sergey  

I am working on a solved problem of Piping Network that uses hardy cross method to solve using Mathcad. The book has used some old conditional statements that are now available in Mathcad Prime now. i.e "Otherwise" with If conditions. I want to know how to correctly write the same in new Mathcad prime. I have the screenshot of the problem shown here in old version. I can attach the sheet if u like.

I recently encountered an issue with Prime 7. The function odesolve doesn't work the way it used to in Prime 5 and I can't figure out why.  I'm updating my MathCAD sheets to Prime 7 and my current header and coding standards, and finding that there's an issue with odesolve.  Here is my solve block showing the differential equation for deflection of a beam. It's a simply supported beam, so deflection delta at 0 and at the beam's end L are both zero. E is in units of GPa, Iy in units of mm^4, length l in units of m, and M(x) in units of kN*m. I have verified that all units are correct.  When I open this MathCAD sheet in Prime 7, I get an error "These units are not compatible", but when I open it in Prime 5, I get no error and the thing works.  What is different about Prime 7 that causes the functionality not to work anymore? MathCAD sheet attached.  Please help! Thanks!
