Mathcad

Hello, Community.I have a question connected with hydrodynamics and natural circulation.As you know, in such systems water changes its state to steam and moving upwards the pipe without pumps.You can see the photo of the system in my post.The problem is in water tank(water is in normal condition) which is located higher.There is a system of 140 tubes inside; it is not so easy to find an equation which will show where the steam(temperature is about 202 degrees,16 bars) becomes water during the process of condensation(i.e temperature distributions in pipes). Pipe pattern is not so important.In addition, defining the preferences of water in downward pipe is complicated either.If you have an experience with such problems (maybe even templates), I will appreciate your help.Thank you for the attention!

Hello,I'm trying to plot a function from Hibbeler Mechanics of Materials in Mathcad Prime 3.0 but I'm not getting any results.I put in a figure for P (15N) and for A (100mm^2). So the bar on top of the page isn't rectangular but square (10x10mm)Theta = 30deg is not producing any result.Somewhat below on the right I tried to list all theta angles from 90deg to 0deg: no result.Obviously I do something wrong here. Please help.Thanks maurits

Hi everyone,Can anyone help me to program this plz:Knowing all of: Fi, a1,a2,a3, gama, beta,delta t and u0, u̇0 and ü0Thank youBily

How can I gat a Real and positive root - see the picture and attach (Mathcad 15 and, pardon, Mathcad Prime 2.0)

By gentleness is there an expert who can tell me if the attached inverse Laplace  transforms are exact?Thank you very much.With best regardsF. M.

Just installed V15. I was told I could download the E-Books (primarily the Mechanical eng. library. ie: Roark's Hickey etc) I followed the link in the getting started guide but with no success.... Can anyone help? it appears the documents you get are less than helpful..Wade

Recently i have used MathCad prime to solve Calermann linearization to transfom a non linear ssystem of differential equations to a linear state equation and mainly i mam studying triangular upper systems. HAve someone interst in this??

Hi,I have upgraded Mathcad 15 to the latest version of Mathcad 15 - (M045 [MC15_M045_20151202]) and discovered that a feature of the Windows 7 Professional operating system is preventing me from Inserting Word docs into Mathcad.  Also Word text blocks within a Mathcad 15 program cannot be edited or opened.  The "feature" that seems to be a cause is USER ACCOUNT CONTROLS (under control panel).  When I set it to NEVER I can edit and insert Word files and text blocks.  The IT department has deemed that USER ACCOUNT CONTROLS be turned on however so after a while - 1/2 day the feature turns itself back on and I am stuck again.  What can be done? The previous version of 15 did not have a problem with USER ACCOUNT CONTROLS being ON.  I like this newest version because it seems a more stable (less likely to crash) so don't want to go back.David Born

Hello,I have to create a large matcad-document under prime 3 und want to devide it into numbered chapters. Is there something like a MS-Word chaptering, so that an insert between existing chapters would renumber the old chapters.Or what is the preferred method to get numbered headlines?

Sorry if this question might seem trivial or a repetition but here is my question:I will use a simple function to explain my problem -  If I have a function say f(x) = x^3+20x+20. And x is a range variable e.g x=2,4,6....20. If I plot in Mathcad the function f(x) vs x, I get a polynomial curve. Now, If I say, f(x) = 22.375 is a fixed limiting value for which I want to know the value of x at this limiting value of f(x), how do I tell Mathcad to give me this value of x for which f(x)=22.375. Is there a program or Mathcad function that I can write for Mathcad to solve this for me.I have given a very simple function to explain my problem but the function which I am dealing with is much more complex. In order to add depth to my question, you can imagine the function I am dealing with as the stress on a machine component that depends on displacements of the component. At the start of my Mathcad worksheet, I define the displacement as a range variable, e.g. x=0,1,2...9. Then through a se

I have defined 2 range variables and an equation that uses these variables to create a matrix.I would like to plot specific columns of this matrix against one of the range variables.I have tried everything I can think of.  Running out of ideas.I am a student trying to learn Mathcad.Would appreciate any suggestions.  Thanks !

Hello,My name is Daniel and I would like to kindly ask you for help with while loop. The problem is that i cant calculate this loop because it looks like it never ends. Any ideas why? Can somebody look at it for me please? Here's my code:And here is how it should work step by step

Hey,maybe anyone can help me.During Readexcel of a column i encountered an error.I have the columns in excel via a when function so that: when(A1=0;"";A1) ----> Need a NaN in mathcad when the column in Excel shows a zero.THe problem is the vector in mathcad is not NaN it is ""And when i want to do a  max function mathcad encounters an error.So i would need a NaN so that i can calculate with the vector something.Now, how can i manage the function in excel so that in Mathcad the empty cells are regognised as NaN so that i can calculate somthing with it.I dont know how i can do the function in excel.Best thx ,Stefan

Heyho,best thx to the forum i could manage a nealry complete automatisation of many calculations.Now i have more difficult Problems and i hope i can solve it.I have now very complicated equations and the way to calculate a certain value is per iterativ methode.Now for example i need to calculate a Force:F=f(.....variables....b)Now at beginn i calculate b with a startening equation (gives a startening point of b)The next step is to calculate the force.After the Force (initial force which gives a value but is not the right force) was calculatedThe problem is now: For a detailed calculation, the variable b is depending on the force, which was calculated before.so:F=f(.....variables....b)b=f(....variables....F) --> there are 2 equations for b .... an initial equation which is simple and the complicated one (b=f(....variables....F))So for me looks this like an iterative solving. I was thinking: I want to start with the initial b and F value and change F, so that the residum of b is less

Hello,I was wondering why when I define a counter variable like "i" and assign it to a vector the result display a "..." and not the actual value I just assigned to the vector.It is a little annoying to have to type out the variable again to display the value, I would like it to display correctly without having to retype the variable.See below:

Good Morning Community,I have having a hiccup here with a file I have put a substantial bit of work into.  The file has been working fine for weeks including this morning however now I am getting an error listed:The file type is not supported.Log is located atC:\ProgramData\PTC\Matchcad Prime\Logs\MathcadPrime_Exception_20151208_095225.logCan anyone please assist me in recovering this file?  I have a backup saved from yesterday but I'd hate to reverse almost a full man day of work!Thanks so much,--Adam

0down votefavorite I want to simplifying radicals in Mathcad. I have expression with product of radicals and want use this rule of transformation:The product of the square roots of each factor is equal to the square root of a productHow I can do it? For example,  srqt(a)*srqt(b) as sqrt(ab); sqrt(a-1)*sqrt(a+1) as sqrt(a^2-1). Comment I have complex expression that can simplify by use last transformation, but Mathcad don't view how simplify it, how explain Mathcad use above rule?

how can i find arc tangent?

In the x-y plot,the plots are not copying to thepowerpoint clearly, when I choose dotted lines(Traces--> line-->dotted lines)Please go through the attached filefor clear understanding of my question.Please help.

I have created a programme for Mone Carlo Simulations but now want to get an output table to show what would happen if I created more and more simulations.In the attached file the basic problem is using 1000 simulations which returns 0 failures in my problem. However, I want to see what happens as the number of simulations (Nsim) increases i.e. I want a table with Nsim in one column increasing and the number of failures in another column also increasing.Any help really appreciated.

Hi everyone,I met a question, when I use "pdesolve" in mathcad. The failure is listed in the picture as following:It told me that the second-order are not allowed, but I have another successful example from the website, which can be seen in the following picture:In the above successful case, we can see it also contains uxx(x,t), which is second-order derivative. Anyone can help me about my failure in my case? I attach my input file in the annex, please kindly find it.Best wishes,Jason

Hello all, i am new here and struggling to get this transfered.My current setup was MathCAD 14 on uses workstation with a Floating license install on a Windows XP .I decided to move this to an official license server running Windows Server 2008R2 64bits. I contacted PTC License management to generate me a new floating license with my new info which they did.I tried to install the PTC License Server with WildFire 5.0 ( M050) but i am never poped the question to browse to my license file. When the installation completes it only seems to have copied the install files here : C:\Program Files\ptc_customThe deamon - lmgrd.exe are no where to be found. I presently have LMTools running other licenses on this server so i decided to configure a new one for MathCAD. I open LMTools go under Config Services and createa new one. I copied the old deamon from the other machine ( ptcd_exe ) and used another lmgrd file from another application. All gets created ok but the Windows service one created doe
