Mathcad

Hello users of Mathcad : ), user of Mathcad Prime 10.0Here is a picture of my problem. I am trying for days to solve it, I just don't understand why it won't work. I need it for a homework.So, I’m working with a rectangular channel where the flow area is A = b × hn. The problem is that I don’t know either b or hn, so to make things simpler, I just assumed the cross-section is square – meaning b = hn. That way, I only have one variable to figure out.I then rewrote the whole discharge formula so that everything (A, U, etc.) depends only on hn. All the other values like the slope and the Strickler coefficient are given.Once I find the hn that gives me the correct flow rate Q, I can always scale it afterwards, like double hn to get b and turn it back into a rectangle if needed. The most important thing is that the flow stays the same.So theoretically, this should work fine, but Mathcad won’t solve it, and I’m trying to figure out what’s going wrong.Thanks for any help. 

Find attached a 3D stiffness analysis I have written in MC-15.The analysis includes member local x beta rotations, member end releases and forced displacements.It will analyse up to 1000 members and 500 joints. The 3D graphics can show selected joints/members/properties/loads/supports with accompanying lists for checking purposes. Given the limitations of plotting member end to member end, which can create false members, the plots of members are made using single points along the member. the density of which can be increased or decreased using sliders. This also allows for sectional plans and elevations to be viewed, again with the use of sliders. Note always push the reset button first as the Mathcad for some reason can sometimes already set the sliders away from the default position. Joint equilibrium checks can be performed on any selected joint and the resulting data exported to Excel which can be used for joint calculations.local selected member shear/bending a

Hello,I would like to be able to solve trigonometric equations with Mathcad 15, but I can't.Example:What is x if cos(x) ≤ 1/2?Can someone tell me how to do this?Thanks in advance.Richard

Hello Mathcad community,Can anyone tell me where the error is?Regards,CarlosRomero

 As the picture above, I want to get the max value for the function K，under a certain condition, but the max() return the value like a matrix，so  how can I get the right value?

Hello PTC Community, Is there a way to insert borders around text or math blocks?

Convolutional integral of square signal and triangle signal is well knowen probrem.How to find the maximum value of the output signal? Prime's symbolic engine sometimes fail for convolution integral. 7/6 is the answer I want to get. Prime 11 sheet attached.

I am trying to solve this equation without success so far  am I missing something here or the equation simply does not have a solution?mathcad prime 9.0.0.0thanks!

Hi, Been lurking around here for a decade but never posted before. I just upgraded from MC14 to Prime10 and struggling with things as I get used to it.(1) How do I add additional sheet/page sizes? Specifically I am trying to add A1 and A2, right now it stops at A3.(2) What is the trick to using Find/Replace for subscripts? I tried Test.Test and TestTest but neither returned a match. I did find a post about this related to Prime6 but I figure it must have been addressed by now since I am 4 versions past that... Thanks!

Mathcad Prime V10.0.0 is failing to convert a V15 Mathcad file with a .xmcd extension. The file was originally created in a much earlier version of Mathcad - possibly V12 - but was used periodically using V15.After failing to convert, Prime creates a new file with a .mcdx extension to it. Does anyone have any advice on what the issue might be and what the next step could be? For the avoidance of doubt, I could previously open, edit, execute and save the original Mathcad file using Mathcad V15 without any issues.

Can somebody give me a list of course outline for MathCAD training? The experience of the trainees is from slightly have knowledge to expert level. Your help will be appreciated very much.

Beginner here. I followed this topic: Solved: Using results from output of function - PTC Communityhowever, that example generates a vectorI am trying to do it for a matrix, and I get instead a long vector:How can I make it so that the values of alfa/phi changes in the rows/columns returning all the results from the equation of P.  edit: attached a file and using mathcad prime 9.0.0.0

Having trouble here understanding why the red box shows up with the "These array dimensions do not match." error message.

Hello,I have attached Mathcad prime 9 document.  I'd  to iterate thru sections and select the proper section size that satisfy certain design criteria. On page 3, the TC sections are listed as shown belowThe member is selected manually until the interaction ratios (IR) on page 6 (shown below)and interaction ratios on page 11 (shown below)are all equal or less than one.i Just want to automate the process. Thank you for your assistance!Sam

The answer of Make one ohm by one ohms is below. Each current of resistor must different. Make one ohm by 2 S and 2 ohm resistors. Each current of resistor must different.   This makes 1 ohm but same current. So not the answer.    This makes 1 ohm but same current. So not the answer.

Hi guys, I need your help to solve the problem that I attach belowi have version 11.0 I wish to find the maximum value of a function containing a range of values in z.receive my best regards

Hello All, I have a mathcad project where the output is required to have in a matrice form which I am unable to. The function will work like the following, for each value of beta it will give a column of outputs and thus for the number of varibale beta, it will generate corresponding number of columns. Please help with a solution Thanks

Hi!Is there a way to implement MathCad Prime Advanced Controls to execute WRITEPRN function on button press using Version 10 Advanced Controls? This is so that WRITE or APPEND will only be performed upon the user clicking on the button. Thanks!

Hi,I can plot Magnitude and phase separately , but not in the same chart as primary and secondary axisPlease helpJacob

Not sure if this has been updated in the newer versions of MathCad, but is there any way to preserve internal hyperlinks when printing to PDF while also maintaining the formatting? I have a 70+ page report that has a lot of specific formatting that I worked hard on and would like to keep. When I save as a PDF directly, none of the links work but the formatting is perfect. When I safe as a Rich Text Document, the internal links work but the formatting is gone. Is there a way to keep both the formatting and the links? Currently using MathCad Prime 9.0.0.0

Hi,I just want a simple range in matchad but it seems really difficult All I want is a range from 5 to 45 in 0.1 steps. The typical definition doesn't work. Is there an easy way to do this? I tried the typical 5, 0.1 .. 45 but i get an error even though the mathcad support docs show that this should be allowed....

There seems to be an error regarding logical statements in Prime 10.0.1. See below.The expected output of all statements is 1. It seems to only be a problem when using units. Is there a fix to this? Thanks

Dear all, I’m experimenting since a while, with MathCAD Prime 9.0 and a specific spreadsheet, what I’d classify as “numerical instabilities”.I’ll explain better. I’m dealing with a complex spreadsheet; this last:Reads from an Excel file the input dataRecalls (include command) a spreadsheet defining a function of 6 variables  To be noticed that the above points have not created any trouble in previous spreadsheets      3. Involves recursive formulas with matrix multiplications and inversion     4.

As the title says one of my files got corrupted and i don't know how to recover it i've tried converting it into zip and recover it with some tools found online but nothing works This file is important as it contains the contents of a important project that i have to turn in in a couple of daysThe problem started today as my Mathcad wasn't starting and then i saw a thread about deleting user config i did and it worked Mathcad was starting and most of the files are available but this one isn'tPlease help me I'm quite desperate even tough its not much i already continued with the results from the equations in this and I'm not sure i can replicate them
