Mathcad

when running mathcad 15.0, I get a message to repeat the licence wizard configuration. At the end of this, I get a message like "this demo is no longer available2", however the software is not a demo

Hi guys I have 2 sets of data kz.b and kc and the refence variable z.b currently i can interpolation to find what kc is when z.b is equal to a value hence the below; however there a various values of Kcphi which i may need to interpolate between such as if kcphi was 6 i would then need to interpolate the value between kcphi5 and kcphi10 to then return the value and interpolate z.b to return the vlaue i am after. i was wondering if there is a function that could be written to help with this Thanks 🙂

Hi, I'm trying to plot a function but I get an error and I'd like to ask:Can I define a variable in a range between two other variables? and if not, how can I do it differently. Please see X3 variable and Y3(X3) function. thanks,Eleni  

Hi guys I have developed at mathcad worksheet that wish to publish to clients, the client has Mathcad licences and therefore can access sheets or templated provided.  Is there a mechanism to allow me to provide controlled access to my sheets/templates ? I believe there are two options 1 - REST API - access external data source to validate user credentials 2 - Build worksheet template for HTML and provide control with access via the webpage  If anyone has any experience with this please let me know thanks 🙂  

Dear all I don't know any code or any Languages only Mathcad Prime. Please help me my question below. My purpose is to get Platform that can order Mathcad prime sheet Open Run Save and Close automatically step by  step to get Text File without open and run manually that it hard to do with many sheets. And I also attach relevant file as below Best regards  SPRstructure  

I have an old Mathcad 13 'mathsoft' disc that does not have the product code anymore. Is there anyway to still download the disc onto my new computer?

Добрый день.отправил заявку на пробную версию mathcad, но ссылка или файл на почту не пришли, проверил все папки в почте.

As the title, cannot open it suddenly.

Hi all, I want to solve the following 2 equations for all v values: Since there are 2 unkowns (Fo(v) and Fc(v)) and two equations, I want to obtain the Fo(v) and Fc(v) formulae since that should be possible. I tried to find this formulae using the 'Find' function in mathcad prime:However, that didn't work. Attached you can find the worksheet. Really appreciate your help in advance!

I just purchased and licensed Mathcad Prime 7.0.0 and want to check that it correctly converts the XCMD files we create with Mathcad 15.  The PTC 'Migration Guide' says: "To start the XMCD, MCD Converter ... click 'XMCD, MCD Converter".  When I do this, it says to install XMCD, MCD Converter  using 'setup'.  It also says "Alternatively, you can start it from the Start menu". But, I can't find either .'setup' or the Start menu.  Please advise.  

I haven't used your program yet, but it says that the trial license has expired

Hi community , Once again I call on you .my problem:I have a mechanism with a non-linear movementin input, I have a linear displacement, and in output I have an angular displacementthis displacement follows a behavior curve I want to drive the input with a motor, so here is my problem.I want to find a max speed value of motor to reach a given angular position. But also that time is linear that is to say, if I want to go from 0 degrees to 60 degrees (for example) what will be my lowest linear displacement time (constant speed value at output), and what will be my motor control curve the solution I found is cut the curve with linear parts,but I don't really like it because it's DIYI don't see the way to get there, maybe with the derivative If someone has an idea   

Hi, I'm trying to build a program so that when I choose a variable to present a set of calculations but when I choose another variable to see in the mathcad spreadsheet another set of calculations. Do you know if this can be done?I was thinking the a,b & c to be different mathcad sheets. Please see attached thanks,Eleni

can you convert now mathcad format xmcd into mcdx, please

I hope I have solved this old interesting problem - One catenary problemSee please pictures and attach (15 and Prime).But at G=0 and x.0=1 m I have not one chain - is it an error of Math model or of a numerical method of 9 equations solution?At x.0=40 m and others not at two fix points all is OKWerner! Where are you?

Its not letting me open a case logger with my product code:(I chose to not include it here) but it is for a One Year Student Term LicenseIt say it is invalid..Cant download mathcad 15website say i have insufficient privilege's on the download page.From the email:"If you need the PTC Mathcad 15.0 software, it is available for download (using your Product Code) here: https://www.ptc.com/appserver/lm/mathcad/download/index.jsp"This link doesn't let me access mathcad 15.Why does nothing work?I just want mathCAD 15. I do not like prime, I do not like converting every file I do at school and vice versa.

Greetings, Here is something I enjoyed working on. I couldn't find the answer online, so I had to figure it out myself. The challenge was to divide a square into 7 equal parts. Each part had to be as compact as possible (minimum perimeter to area ratio), so I knew that the trivial solution of dividing it into 7 long, thin strips would not work. After drawing several iterations, I came up with this model. A hexagon is centered in the square, rotated at 45 degrees so that two of its vertices align with the diagonal.  Each shape has an area of 7, in this 7 x 7 square.  If this was a tile fastened to a surface, then the fasteners would be placed at the centroids (stars) to prevent uplift in the most efficient way, supposing that they want to use 7 fasteners and not any other number. Fastener patterns with other numbers are easier to figure out. The next-hardest one was with 5 fasteners, but that's just a simple square in the middle instead of a hexagon.  

Hi everyoneI get an error message trying to use polyroots: this value must be a scalar. It seems to me, that the exact same error is also in the Quicksheet (see image).Any hint would be appreciated. Thanks a lotRegards, Claudio 

Hi everyone,I have an equation that I would like to let Mathcad simplify for me.  It looks like this:ok 🙂 I know I could simplify it myself, but please consider this an example! If I select the left side and then Symbolics > Simplify I obtain the highly unsatisfying result:what I would like is that pi remains expressed as pi! I have tried, remembering another thread, the "symbolic undefine" pi:=pi (above the equation) but apparently it does not work! Am I asking Mathcad 15 too much?   thanks for any suggestion! Best regards, Claudio PS: no, I do not use Prime 😉PS2: the equation is derived with some manipulation from ASME Boiler and Pressure Vessel Code, Section III, and is related to the allowable stress in a pipe product, under known inner pressure and external moments, at design condition.  

Dear All Please help for calculating  Transformation of the nodal coordinates of the spaceframe element, I stuck here both theory and Mathcad Prime. I attached file of Mathcad prime sheet and lesson and example. Best regardsSPRStructur  

Can someone help me with my program? I think I am lost in doing a program in Gauss-Seidel Method of Iteration. Thank you in Advance.

Hi, I need to solve this equation. I tried the solve function to solve it, but it does not work. I managed to solve it with wolfram,  please see the pictures below. Is there a way I can solve this?  

As per this thread , same issue. Hello Luc,   Many thanks for developing the LODEsolve function.   In the explanation is stated: " You cannot specify an initial condition for a value of the independent parameter other than 0. See examples on how to deal with that situation".   I have a curved beam with three boundary conditions at each end of the beam (theta = 0 and theta = phi). The beam is described by three second order differential equations. In can't find an example'that deals with this situation. Is it possible to have multiple boundary conditions at different independent parameters? If yes, can you explain how to handle this situation?   Kind regards,   Ton    

I have converted numerous MathCAD 15 programs over to Prime. In doing so I am having issues with the 'Include' look-up not reading/working properly. About half the time the source/path works just fine, but on the others I get a warning - "PTC MathCAD is using the CWD, Approximate Equality, Strict Singularity Check of the current worksheet, not the CWD, Approximate Equality, Strict Singularity Check settings from the 'Source Worksheet'" It also tells me there are calculation errors in the Source Worksheet when there are none. Please advise

is there any way to recover a file in mathcad prime 6.0?
