Mathcad

Hi,I recently open the download section on PTC's site (link: https://support.ptc.com/appserver/auth/it/esd/product.jsp?prodFamily=MCD ) and see the following message:"VERY IMPORTANT: Critical issues with Mathcad 15.0 M040 in handling matrices with 256 or more elements. Please refer to CS218119 - Warning: an unrecoverable read error has occurred. xx regions could not be read from this document while opening specific worksheets in Mathcad 15.0 M040: http://support.ptc.com/appserver/cs/view/solution.jsp?n=CS218119CS217297 - Error "Operation aborted: max-element-depth constraint violated" occurs when evaluating big matrices in Mathcad 15.0 M040: http://support.ptc.com/appserver/cs/view/solution.jsp?n=CS217297 PTC will release a new maintenance release Mathcad 15.0 M045 that would address these issues soon."

We’ve recently found, through customer reports and our own testing, an issue with matrix definition and evaluation that was introduced in PTC Mathcad 15.0 M040. This issue affects matrices of 256 elements or larger and can lead to a failure to evaluate and the possible loss (if document is saved after failure to evaluate) of matrix definition regions themselves. This tech support bulletin has more information on this issue. We intend to release PTC Mathcad 15.0 M045 as quickly as possible which will include a fix for this issue. The release date for PTC Mathcad 15.0 M045 will be posted on the Product Calendar page soon.

Hi...how can I use  API to make a interface application (look like a clip in PTC Mathcad | Engineering Calculations Software

Hello everyone.I made the following function in VBA (Excel) to retrieve the value of the variable B from the mathcad file using the API.The Variable is defined in the file with a unit i.e. B := 2 mPublic Function test2() As Double    Dim objApp As Ptc_MathcadPrime_Automation.Application    Set objApp = New Ptc_MathcadPrime_Automation.Application           Dim b As Ptc_MathcadPrime_Automation.WorksheetReadonlyOptions    Set b = objApp.CreateWorksheetReadonlyOptions    bb = b.SetOptionValue(WorksheetReadonlyOptionNames_RequestToUpdateInputsEnabled, 2)        Dim objCalc As Ptc_MathcadPrime_Automation.IMathcadPrimeWorksheet3    Set objCalc = objApp.OpenEx("C:\Users\kai.jakob\Desktop\Testo.mcdx", b)    Dim a As Ptc_MathcadPrime_Automation.IMathcadPrimeOutputResult    Set a = objCalc.OutputGetRealValue("(@LABEL VARIABL

Hi All,I currently have run into a small issue with the way that Mathcad displays the unit system when using the explicit command. The default in-built unit system defines a Force * Distance as joule rather than a moment which is what I want. To avoid having to change from joules to moments (N*m) every time I calculate the capacity of a beam I have created a custom unit system which defaults force * m to kN*m. However, as you will see below when I call on a result that is calculated earlier in the mathcad sheet with the explicit function it will cause unnecessary unit conversations (see 1x10^4 / 1/x10^3). Is there a way of controlling the units in the situation? I am keen to find a solution for this as it complicates the calculation for the person reviewing the work.FYI I have a mathcad prime 3.0 so if there is a solution with this version I will happily switch.See below attached images:Kind Regards,Liam

Dear experts, I'm a third year Agronomy major from Costa Rica. I'm calculating degree days built up for every day in a given data set with over 7 000 observations. Each observation is an hourly average so 24 observations make for 1 day. There are around 300 days in my data set. Growing Degree Days is a measure of acumulated energy in a system during 1 day and it is calculated as follows:Max T = Highest temperature measured from 0000 to 2400; Min T = Lowest temperature measured from 0000 to 2400; Tbase = Minimum temperature required for crop growth (specified by literature)GDD = (Max T - Min T)/2 - TbaseSo, what I want to do is grab my data set, split it into 300 or so chunks of 24 observations. Out of those 24 observations I need to calculate the maximum and the minimum. With those values determined I can now calculate GDD. I need the algorithm to store that value in a matrix and move to the next 24 observations. If the first day is from obs 0(start) to obs 23(end), the second day is f

Hello,How do I start Mathcad from c#? Try to create a new object of type Ptc.MathcadPrime.Automation.Application there is a notimplementedexception thrown.Regards

Is there documentation on this?

I would call this behavior a bug. The integral is only found if the symbolics is forced to float mode (it also happens if you use the "float" keyword).Does anybody know when it was introduced or can anybody confirm the bug in earlier versions of Mathcad than M15 M030?

Hi all!I'm trying to embed an excel file in mathcad 14 using the    insert--> component--> excel file--> "create from file" (display as icon).All I want is data from A1:A166053  (i know it is a lot of data ), this data represent the significant wave height since 1957. After I "create from file" I select 0 input and 1 output and then define the range i need. When this is done the icon appers in mathcad and I define the  name. In this case "Hs". Then the error message "The range value specified is invalid" appears...What am i missing?? Regards Sigurd Næss

So is there a way to do the second equation with symbolic operator?Shawn

Hello,I am attempting to program a simple for loop to increment a single variable in an equation and plot the equation as a function of the variable. I have attached the mathcad worksheet. The issue arises on page 3 of the worksheet. The value I am trying to find is "Sigma_max" as "e" increases from 0 to 1 in 0.01 increments. I'm sure this is easily remedied and due to my own mathcad ineptitude. What am I missing?Thanks in advance!-Ryan

hi,how to get total number of pages in mathcad sheet in VBA or .Net.

I have been having problem with Mathcad Prime 3.1 crashing lately.  First, when I load my files, some random equations will be red-circled as "Unknown Error: mpl%_Exception".  (see attached image).  As soon as I start changing the values on my worksheet, Mathcad would crash.At first, I thought it might be migration issue from my Prime 2.0 file to Prime 3.1, but I realized even if I try a simple calculation in a new file, Mathcad would crash.  ex. a:=1m, b:=2m, c:=a+b=  (see attached image)I am now stuck, not being to load any of my worksheets.  Could anybody offer any suggestion or explanation?  I am running Mathcad Prime 3.1 Express, on Windows 7 service pack 1, 64bit.  Intel Core i5-3470 CPU 3.20GHz, 8 GB RAM.  I did try reinstalling the software with same result.Thanks in advance for helping out.

We use Mathcad for calculations of structural design and create a report of it to be submitted to the customers. While I have created a Mathcad file having set of calculations for standard product, there is a slightly different variant of that product that requires slightly different calculations to be incorporated than the standard one. Now, I want to standardise the template of the report such that, there will be two options (Radio buttons etc) in the beginning to select the variant, and based on the selection the set of calculations will be displayed. Thus I don't have to create two different types of template for the same product.The way of doint it can be hiding and unhiding corresponding regions/pages based on the selection of variant but I don't know how to do it.Any thoughts?

Hi all, I have a long equation calculated by Symbolic solve. It is very long and it is very time consuming to tell the coefficients of each term. Can anyone help me with the attached mathcad file? Thank you!

From CreoParametric 3.0 M030 you can embed a MathCAD sheet into your model. That works fine with CreoParametric, but I do not know how to make this information contained in the MathCAD sheet visible in CreoView.Any ideas?

Can anyone help me evaluate this integral?

Narrow backfill is a common practice in hard rock excavation.  Most common cases are construction of retaining walls with a short distance from rock face cut which is usually carried out vertically.The formula used in calculations is partially derived using symbolic calculations. The formula is similar to that to compute pressure on varied pipes.  Kee H. Lee, P.E.

Can anyone help me with this integration?. I cannot seem to complete the integration.Thanks

Hi all, if I have the three variables in three equations, would you advise me how to use mathcad to express the derived expression of the variables?I have three unknown variables x,y,z, and three pre-defined values a, b and c. If I have x+y+z=ax+2y+3z=bx+3y+4z=cwould you teach me how can I use mathcad to express x, y, z as the expressions of a, b and c, instead of assigned the numbers to a,b and c then solve x,y,z as the fixed numbers? Thank you!
