Hi there It has been days since I started working in this task , but couldn't reach the right result I need to draw this graph in mathcad I have two values >>z ( depth a reading taking each 0.02 m )  so in one meter we have 50 z-values and qc ( resistance in that  z depth)  I need to write a program that will choose the minimum values of ( q , 12 MPa ) if  change through z depth in one meter is less than 12MPa and the minimum value of of ( q , 15 MPa ) if the change through one meter is bigger than 12 MPa the sheet is attached Thanks Yusra 

I have a Mathcad 15 file where I can plot the absolute value of two functions that have real and imaginary components. When i converted the file to Mathcad Prime 11 it provides error. Because the graphs are at the end of the calculations sheets, i am only providing screen shots for now, to avoid having to attached the complete calculation sheets. But let me know if i need to submit the complete files for review. thank you in advance, Rogelio

In my HVAC load calculation, I have the units in the matrix column in Watts.But, I  need units to be Btu/hr.I tried various options without success. I request help.Pl. see below.Also attached Mathcad file.

Hi, and Merry XmasI' trying to work with LeastSquaresFit and functions and variables NOT unitless, and I'm having problems.I have a variable and some data obtained by interpolationI want to find a value for  such that the function  fits the y values.I have definedDimensionally everything seems correct:But, when I try to use I get: "These units are not compatible".Which units? Everything now is unitless!Thanks

Hi,I have encountered a problem. Normally, I know how to prepare a list box, but in this instance, I need to create a dynamic list box such that input from another list box influences it. Specifically, I need to create a list box asking for the “Bolt Type,” but for that, I need two inputs, similar to a real case scenario: Bolt types depend on “Standard” and “Unit System.” Please find the attached image that I saw in a PDF. Please help me to create this in Mathcad Prime. Thanks in advance. The image: 

Hello,   As you may have seen, there is a recently introduced bug that is affecting Mathcad file attachments. We are investigating with the assistance of Khoros but are having trouble reproducing the issue. So, I was hoping a few of you might be able to help us out. If you are posting an attachment, could you try first without zipping the file. If it fails, go ahead and use a zip file but message me with a link to the post and description of what happened.   Additionally, if any of you have issues with attachments and have the opportunity could you try adding attachments from a different device on a different network and let me know the results.   Thanks!

This should be a simple problem, but the units in MathCAD don't work together...125 hp...but instead I get...Is there a way to make the units work with the units or do I have to bypass all of all of that to put in my values without units?See attached MathCAD Prime 9.0.0.0

Hi guysnew hereI have worked with mathcad a few times, but never with very complex sheetsI'm trying to do a calculation sheet for the Cross laminated timber (CLT) gamma values, which are used to accound for weak layers in a laminate.I have been able to create the matrices, but in a non automatic way. I'd like to be able to make the sheet build them automatically, with the correct size for the given niumber of layers.The PDF from ProHolz provides the calculation on page 5-7, and the indices are already given for placement in the matrix.But I cant get it to work, I always have an issue with the indices i-1 when its the first line, cause the indices simply don't exist for 0...Basically I want to just write down the number of layers, and the dimension, but then it should be automaticthe Matrix V and vector S always vary in size depending on the number of layersor use a trick like this, because once the matrices are build, I could just use the right one, but for a 3 layer -composition, the

Currently using MathCAD v15 (M050). I have Prime 10 but am having licensing issues at the moment. Anyway, I'm having trouble understanding why the invlaplace function won't evaluate as shown in the attachment. If I remove the absolute value sign, then it all works as expected (am I just running up against a domain issue and need to use the "assume" keyword.....or something......?)Any advice is welcomed and appreciated! If Prime 10 has no problem with it, then that's my answer (just gotta lean on IT to get the license issues sorted). Thanks!

Hallo Mathcad User,ich nutze Mathcad 10. Und wollte fragen, wo man benutzerdefiniert einstellen kann, dass mir Gramm in "g" angezeigt wird und ich nicht "gm" schreiben muss. "gm" ist ja die vor eingestellte Einheit für Massen und ich würde es viel gerne als "g" stehen haben.Liebe GrüßeSaro 

So a few days ago i made a post of my graphs not working. Back then i asked 3 teachers to look at it but they all couldn't solve it. Luckly the ptc community could.But now i need to present the solution and i want to add fancy things so it looks more complex then it is.For example first check of something is a range but somehow my second value wont work for it.Any other idea's to make it look more complicated? 

Maybe I am the weird but I would like to be able to format results using commas to make the "thousands" and "millions" clear.I realize that one can use engineering notation with powers of 10^3, 10^6, etc. but it would be nice to be able to have "3,000.00" or "42,000,500"One has always had that available in Excel (or its long departed competitors... Anyone remember Visicalc or SuperCalc?)--Doug

Hello,I'm trying to make an "If" statement on Mathcad 15 that is able to pull a value for Alpha based on the Exposure Category assigned (B, C or D). I did this on Mathcad Prime (see snip) but having problems replicating it on Mathcad 15. I defined exposure earlier as " E = "B", but when i try to type the if statement it says "Cannot understand this syntax". Any help is appreciated, Thanks! 

Hey!So for my industrial desing  class i have to calculate the force on a crankshaft.I made the formula's but i cant seem to get my graph. I think my Phi is not a vector but i dont know how to fix it.  I tried using another word for it  and other things but nothing works. any idea's? thansk a lotI use mathcad 11

I need to hire a consultant to help set up a spreadsheet to  parse and analyze arrays of data. Any  ideas who  is out there?

Dear PTC Mathcad Community,I am working in Mathcad Prime on a nonlinear moment–curvature analysis of a reinforced concrete section according to Ukrainian concrete Code ДСТУ Б В.2.6-156:2010 (Appendix A, second equilibrium form).I implemented a step-by-step algorithm with nested FOR loops, conditional checks, and accumulation of results into a matrix Moment_curvature.Problem descriptionI expect to obtain a matrix with multiple rows (i.e., 10 rows), where each row corresponds to the final iteration of strains (εc1, εc2), which have to iterate until the condition of equation (4.3) N<0 is true, and contains:iteration indexconcrete strains εc1, εc2curvature אsteel stressesbending moment MHowever, Mathcad returns an empty table only, even though:the outer loop is defined as for i ∈ 1..n with n = 20the loop body is executedno errors are reportedI understand that my script is one of the few possible ways to solve the issue; thus, with this regard, my questions arose:How can I use a WHILE lo

Hi there, I have a variable with 100 values inside and I want to check every 5 values to find the minimum between them. I need to do that through the entire values ... this means 20 times . I tried to write it this way but not working :  z , and q are related to each other . q is the resistance at z depth .. the results I expect is : the program will check q at each z and will choose the minimum (q , 15MPa) but will do this in intervals 5 values by 5 values .  the sheet can't be attached again . I attached  zip file thanks Yusra 

I have two similar integrals, one with sin function and one with cos function, but for some reason integral with cos causes an error, but with a sin does not. I would be very grateful for help. Integrals are at the end of the attached worksheet. I'm using MathCad Prime 11 if it matter

Hi all,  Looking for some help with writing a program shown in the image provided? Engineering code provided alongside for context. I'll accompany this with the Mathcad file (working with Mathcad Prime 10.0.0.0).  Kind regards, Iain
