I have downloaded a file 'pim_installmgr_mathcad.exe' and try to run it. It opens up, the PTC Installation Assistant runs up to 100%, Windows pops up to ask me to allow this program to make changes, I say yes - and then nothing. Nothing more happens. It just stops. I have Windows 10 Home 64-bit as my OS. I have tried running it as Administrator - same non-resuslt.   Please help

Hi! I'm trying to switch from Mathcad 15 to Mathcad Prime 5.0 but still haven't found any way of writing commas in subscripts without the formula switching to some other format. In Mathcad 15 you could always use the Ctrl+Shift+k to do this but i haven't found any equivalent solution in Prime. Do anyone know of a solution to this problem?   I've already searched the web (and forums) but haven't found an adequate solution to this. I found a post where they gave some suggestions and said something should have been added in Prime 3.0 but i haven't been able to find any references as to how this actually work. Since im working with Eurocode and write a lot of formulas with subscripts i can't be bothered with copying content back and forth but rather need a straight forward way of achieving what i want.   Kind regards, Johan 

Then I flew recently in an airplane and saw a neighbor on the screen of the Mathcad tablet with such a strange example. Then I realized that this is a Jewish or Arabic version of the package.

To all experts,   I am breaking down an investigation I am hoping to do to simple blocks. I am looking at creating “dummy” bi-modal PSDs to meet a specific rms value. See attached mcad15 sheet If I specify the values fn, zeta1, A1, alpha and p is there a way of Mathcad finding the zeta2 value required to get a given rms value? A solve is returning “no solution found” but it works with a Find(). I believe one cannot use Find() in a program   Ultimately, I would like to create a number of f dummy PSDs with the same (or near) rms value by changing the parameters. For example, I would like to specify a series of alpha values and get a vector of rms value   Thanks Regards JXB

Hi   Can someone help me with some pointers to achieve above.   Ideally - file can be dynamic  but will settle for a static file.   Sample file attached

Hi  I defined a function but right below it says its not defined.   Please let me know the issue? Very bottom of the document   Thanks   Prashanth Rajendran    

Find aL and replase to a.L - Ctrl+h No problem to do it in Mathcad 15 How can I do it in Prime?

Problem. A chain is taken (absolute flexible and inextensible thread) of length S and with a specific (linear) mass mc. The chain is suspended at the same height from two ends. The horizontal distance between suspension points is L. A pendant (material point) of mass M is strung on a chain, which can slide along the chain without friction. What will be equal to the arrow of the sag of the pendant?I solved the problem numerically. Is there an analytical solution?

Hi   Attached is a calc Im working on. Everything seems OK until I try to enter a value for epsilon/D and then the program keeps popping that it must be a scalar value. Progressively I wish to use the value of Epsilon/D and then calculate Cf. Here also the program keeps saying Cf is not defined. Kindly assist.   Regards Shastry

I have an initial matrix containing "Yes" and "No". This initial Matrix is named A. A can start with a "Yes" or start with a "No" and the times "Yes" and "No" are in the A Matrix should be unlimited.    In A the "Yes" and "No" do always alternate, they never repeat.   Then there are two matrices which are really vectors; B and C.   I want to stack these two vectors which might have the same number of columns or might not. For this case A, B, and C always have one row.   Recap: A is manually input; B and C are also manually input. Matrix D is generated.             Matrix D is the generated Matrix which is going to have one row. For columns it will have the sum of the                columns of B and C or simply the number of columns from the A Matrix which should be the same as the              sum of columns of B and C.   D’s first element will be

Final goal is to output a Graph with X and Y values.   I am having problems with the generation of the Y values. The Y values depend on weather an initial value is "Yes" or "No" under the variable Assembly.   I would like to replace matrix B and C for a single matrix that will take into account the Matrix called Assembly.    If you look at both examples, SW-1 and SW-3, you will notice that matrix B depends on weather Assembly starts with a "Yes" or a "No". Matrix C is simply the cumulative addition of matrix B.   I was thinking of creating a Loop that starts with Matrix ShearWall.Gap and applies the multiplication ShearWall.Gap0 times (v.shearwall-v.diaphragm) if Assembly is "Yes" or -ShearWall.Gap0 times (v.diaphragm) if Assembly is "No" and then continue doing what Matrix B and C are doing. Stack the C values and be able to graph them.   Thanks for any of your input.

I want to make a dynamic report using Word and MatCAD (15 M045).However, I ran into some problems: 1. Formulas typed and formatted in MathCAD lose their style (underline, italics, etc.) with a special insert in Word. Is it possible to somehow fix this? 2. Noncritical problem: the Russian-language text from Matkad is inserted into the Word with hieroglyphs (solved this problem through the GOST font, it does not give distortions). Is this an encoding problem? I apologize for the errors, wrote through Google translator.   Дублирование на родном языке:   Spoiler (Highlight to read) Я хочу сделать динамический отчет с помощью Ворд и МаткАД (15 М045). Однако, я столкнулся с некоторыми проблемами: 1. Формулы, набранные и отформатированные в MathCADе теряют свой стиль (подчеркивание, курсив и т.п.) при специальной вставки в Ворде. Возможно ли как-то исправить это? 2. Некритичная проблема: русскоязычный текст из Маткада вставляется в Ворд иероглифами (решил эту проблему через шрифт ГО

I try to create a symbolic matrix (in my example, the matrix RES  ).  The problem is that I cannot have the result in the form of a matrix, the only way to obtain what I want is to say that RES is not a matrix and is depending on two others variables corresponding to the indexes of the "matrix" (RES2 solution in the attached file question.xmcd). However, I need to use this result after and I need to have the result in the form of matrix.   How can I do to obtain my result in the form of a matrix ?   Thanks !

I show to my sdudents the equations sin a + sin a = tan a 99% say that it is not correct? But 1%... See please

I have got the letter Dear friend,I am Mrs Maria Johnson, Manager of bill and exchange at B.O.A BANK inNigeria, I would like you to indicate your interest to receive the 1 000 000 Mathcad licensees in aur bank safe, and i want you to stand as the next of kin to late customers who die in plane crash.Thanks for your co-operation.Sincerely, Mrs Maria Johnson.   What is it?

Hello all, whenever I try to solve this mathematical equation, it always gives me an error.  I am pretty sure I am doing osmething wrong or not writing the equationj ina proper way, but until now havnt found out any solution to fix this problem.    It will be very kind of your experts to kindly help me out in this small issue.  The file is attached, in this file you will see "b_limit", which always shows an error for bing_bent, can anyone help me out to solve this please?   Best Ashutosh Mukherjee

Attached is a little problem in 4.0 that has me stumped - not sure how to set it up to solve.   The problem is for a pump - which we know performance of.  I need to find the speed to deliver the required flow and pressure must exceed the requirement (it can be higher) and the speed should be such that the consumer power is lowest while meeting the flow & pressure needs.  Since efficiency/flow/head curves vary it's possible that the lowest power speed delivers more pressure than necessary, but does so efficiently.   Everything works up to the solve block, and despite many attempts I can't figure out how to formulate it. Thanks,

I need to create paths(creating matrix of coordinates) just check image that i have given below is there any simple method to solve this ? this graph has to be plot in x and y coordinates.

To all,   I am looking/thinking about something and would like to know if it’s possible to create vectors populated with random numbers. I have only started thinking about it so don’t throw a stone at me if it’s so obvious.   In the attached mcad 15 sheet, I have an equation which is the sum of j-values (j=3 in my example) Is there a way of generating the values in the vectors in a random way so that the vector length is changed by the user? For example I may want a 1st pass with j=10, then j=20 and maybe j=100   The constraint is that for the vector fnv: f1 < f2 <f3<…<fj   Would this be better set-up as a MonteCarlo problem using mcad buil-in function   Thanks in advance

I understand that my S 2 and L x are both defined as vectors.  I’m using a comparison operator (<) that compare scalars, not vectors.  I have no clue how to make an if/else if statement work.  Any assistance or advice would be extremely appreciated.

hi,   Can we integrate solidworks with Mathcad prime 5.0? if yes , can someone please send me the procedure. Thanks in advance.
