Mathcad

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

Hi, everyone, I trie to install the mathcad prime 7 thru the link below but it didn't work. Does anyone had the same problem? What do you recommend me to do? https://www.mathcad.com/en/try-and-buy/mathcad-express-free-download Error messages:  I don't know exctly where to find the installation log. Sorry if it is a repeated issue, I tried to find a similar post but I could not find it. Regards, Guilherme

Cannot install. Downloaded install manager and every time I try to open it, a popup shows up saying Extraction Failed, File is Corrupt. I've downloaded the install manager multiple times, turned off anti-virus software and restarted computer, still cannot install. Please help as soon as possible.

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,I have a problem with installation of mathcad version 7.0. I have installer, recieved it via e-mail. When I try to install it, after runnig installer, there is only extraction of some files, the window disappears and nothing is happening. I tried to download full version of installer from website https://support.ptc.com/appserver/auth/it/esd/academicFree.jsp but there is no file under the name of Mathcad 7.0. I had the same issue with 6.0 version but on that time there was a full version of installer on that site and it helped. Kind regards

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!  

Hello,   I'm a teacher in Mechanical Engineering and we use Mathcad Prime 5. Since the 1st of januari we can no longer activate our (unused) Mathcad Prime 5 license codes. We don't need to upgrade and want to keep using our remaining license codes, but this no longer seems possible. Our reseller has zero options for this, except to buy a new pack of license codes (and run into the same problem in a few years)...    Does anyone know of a solution for this problem? Or maybe a name from someone at PTC who could help me?   Thanks, Daan

Does anyone know anything about Allan Razdow - one of the creators of Mathcad? I used to communicate with him both by mail and on Facebook, I wanted to invite him to Moscow for a conference. And now nothing is heard about him. It worries me.I visited him in Boston two time. He showed me the house where MathSoft was located. He told me a lot about this Mathcad and why it fell into the greedy hands of PTC. Mathcad was the only favorite son in the MathSoft household and became one of the stepsons in the PTC household. Alen's parents (Razdovich) emigrated from Yugoslavia to the United States before the WW2, where Alen graduated from MTI.By the way, the creator of the PTC is also from Europe - from Leningrad. In general, all the creators of the most popular CAD trinity (Creo, Autocad, SolidWorks) come from the USSR. This is not a brain drain - this is a transplant of brains into more fertile soil.

Is there a way? Possibly through an intermediate format via export-then-import process?

Hi!I have written som output in the excel component, and I would like to define a few values as "NaN" (they are out side my range of interest), but the excel component does not appear to accept NaN from excel. Are there any workarounds? Thank you! (using MC P7) 

Hello,  I can´t figure out by myself the syntax to pass a matrix from excel via SetMatrixValue to Mathcad Prime 7.I was able to write a single variable with "Call WS.SetRealValue("test", 6, "")" with no Problem but I can´t get it working with a matrix. The code I use: Dim MCPath As StringDim path As String path = Ordnerpfad(ActiveWorkbook.Path)MCPath = path & "\Rechenkern\....... Set MC = CreateObject("MathcadPrime.Application") 'CreateObject("Ptc_MathcadPrime_Automation.Application")MC.Visible = TrueMC.ActivateSet WS = MC.Open(MCPath)Call WS.SetRealValue("test", 6, "")Call WS.SetMatrixValue("test2", ?????, "") The variable "test" and matrix "test2" already exist as inputparameters in Mathcad, I simply want to change the value of the matrix like I did with "test". I hope somebody can help me with my problem.
