Upgrading to Mathcad 15 Professional (single user), Professor, and University (student) edition.There are 3 basic steps to licensing your copy of Mathcad:1. Install Mathcad software on your workstation.2. Request a license file from PTC and save to your workstation.3. Tell Mathcad where your license file has been saved on your workstation.The attached PDF tells you how to install Mathcad 15 and request your license key.

Looking to obtain the reaction for 3-5 span continuous beam. Does anyone have an existing Mathcad 15 file that I can reference? Thanks.

Hello PTC Community, I need help with an error that I am getting while solving a summation expression. Please refer to the attached image to see the error. Any help would be appreciated.     Thanks

Good day   Any advice on the following use case would be appreciated. I'm designing 2 non round variable pitch cams. Most of the calculations I've done in Excel but have gotten stuck on finding the angle of rotation of the second cam so that a vector of the cam passes through a point. I can do a Matrix translation and rotation on the vector but need to find that angle. There is a measured geometrical solution in CAD that works, but it takes very long to make changes so would like another solution. Math can be found here, above my pay grade, but I though Mathcad might be easier. https://math.stackexchange.com/questions/2278357/rotate-a-line-around-origin-to-pass-through-a-given-point-how-to-find-the-rotat Express if possible, I do not have Mathcad, but this is a once-off so can do trial if required.   Thanks Trenton

  Hi, can i please know the method for this condition. 1st row value of ADC matrix should compare with ADC_LUT matrix and take the next higher and lower value. for eg-if 3996 from ADC matrix is compared with ADC_LUT matrix , it should take out 3997 & 3968 value from ADC_LUT matrix. similarly for other value to.   Regards, Kishore

How can I add a conditional formating to mathcad sheet similar to what excel. Where the results of a results checks highlights in different colors depending on the results check (ie. if 1 > 0 highlight as green, and if 1 < 0 highlight as red)?

Hello everyone   I want use array in solve block. I attached file "test2". But I have "pattern match exception" error...   I also try without array. I attached file "test1" I have also error, but I can use this result.   Please advise on this difference.    

Hi everyone. Today I faced a very weird issue in Mathcad.  When I define any variable with unit "m" my mathcad is multiplying by 3/m by itself. I was using my mathcad files  without any issue but yesterday I updated my windows from 7 to 10  and since then this crazy issue is appearing.  I mean when I write A:=3m. then when I type A=, it shows A=9. Or when I define a variable as B:= 3 kNm, then it reverts it back automatically  to B=9kN Does anyone knows what is the reason of this issue?  

Hello all,   I want to solve an equation of one variable in combination with a for-loop.   In the appendix I added an example of this problem. How can I solve this?   Thanks in advance!

Hi.The choice of colors seems very limited. Is there a way to get a bigger palette, to have more colors?RegardsLukas

A question regarding mathcad's use of units and one regarding the result of a calculation:   1.  at the bottom of page two, is there a way to delete the extraneous unit conversions (1/m * m * 1/ft * ft)?   2.  in the final calculation on page 4, i would like to have mathcad show the result of each of increment calculations (one value for each value of delta sigma v_i) and then i can add a summation function to obtain the final result shown (0.901 in.   any assistance would be appreciated.

Hello,   I have a question regarding my work. In my file, if I define the units of "lambda" as per "m" then the values of phi have some negative values but if I define the "lambda" as per "cm" then I do not have any negative values of phi. Please help me out about the issue as to why it causes this positive and negative issues only for changing the units. My Mathcad version is prime 4.0.   Thank you, Faisal

Hiya,   (Mathcad Noob here 🙂 ) I'm trying to get Mathcad Prime to do a relatively simple plot using an adjacency matrix and homogeneous data points. In Matlab I can do this quite simple like so:       Which results in this:   Now if I try to the same in Mathcad I get this (dont mind the 3d plots, just fiddling around):     I'm sure its because I don't know what I'm doing, since I'm still relatively new in mathcad. And it might even not be possible to do in Mathcad. But I was hopeing someone could enlighten me.   Thanx.

I am sure there is a simple solution to my question.... give the attached file, I am trying to compute the radiant energy from a fire to a target (using the point source method) and wish to turn the 2D plot into a 3D plot as a function of distance and angle from the fire.  Meaning, if the fire is at coordinates 0,0, I am trying to figure out the commands for placing the target from 1 m to a given distance (in this case 121m) from the fire in any direction along the x,y coordinates and then plot in 3D.... I am sure its easy, but this rookie can't figure it out... Any assistance is appreciated.

Hi , I am trying to solve this equation and it seems it can't be solved because of both "1" from the equation. Could you please help me find what units should i attribute to that values of "1" ? Thanks.  

Does anyone have suggestions on how to actually get support for MathCad? I've been trying for months (closer to a year) to fix a problem, where PTC screwed up and added our new MathCad user to another customers account, because our companies had similar names. Because he is not an admin, I can't get into their software tools, and our software does not seem to be registered correctly.   Emails go months without responses, their phone system is always "experiencing difficulties" and messages left do not get a call back. Have submitted more than once case for this. This is easily the most ridiculous lack of support I have encountered. It's impossible to get a live person on the phone to fix what should be a very simple thing.   Anyone have any ideas how I can actually get support for this software? Thanks! Michael

Hello Everyone   I use MATHCAD15. If impedance is calculated with and without units, it will be different numbers. I am confused. Please give me advice.   I attached file.    

All,    I'm attempting to start what should be a simple geotechnical effective stress calculation. My first step is defining a soil unit weight profile as a function of depth (z) in an efficient and robust method. In the past, I've used "if statements" to control this however they are cumbersome and not very sophisticated. An example of what I've done in the past is shown on Page 2 of the attached worksheet.    On Page 1 I attempted using "vlookup", however I ran into numerical issues and precision errors due to TOL...ideally, I would like to end up with a function that is as simple as the "vlookup" approach, but with the precision of the function defined by the "if statement". Any suggestions would be appreciated...I've attempted "for loops" and "while loops" without any success.    Thanks in advance!

Dear all,   Attached is a sample mathcad sheet, where I created a push button which should write some data to an excel sheet. But if I enable evaluation, my mathcad automatically runs the script in that push button and writes data to excel file (irrespective of whether I click the button or not).    The basic idea is, I would like to make lots of iterations / changes in mathcad, and once I am happy with the output, I would like to write the data to excel (by clicking a button). I wouldn't want the excel file to keep getting updated every time I make some changes to the mathcad sheet.   Required output: Output(0) = "Yes" Output(1) = worksheet.name   But Output(0) variable is by default, defined as "No" and I don't want it to change to "yes" unless I explicitly click the button (because I used an if statement to write file to excel). Kindly suggest changes / better way to achieve this ?   Your help would be much appreciated !   Many thanks in advance, A

Unable to plot 3D graphs when the variables are linked with Units.  Without units I am able to plot the graphs.   While the equation is reveling out correctly and there is no problem and it results clean.  Attaching the source file   

I am working through this tutorial (from this site), using Mathcad Prime 3.0, F000 The thing that is driving me absolutely crazy is tha tI can't get it to solve symbolically, like the tutorial says it should. I am trying to do this problem:However, when I insert the symbolic operator, this is what happens:Why am I getting a numeric solution instead of a symbolic one? It's especially frustrating since one would thing a PTC-supplied worksheet would, you know, work.Any input is appreciated.Thanks.

Hallo guys,   i have a question regarding finding a maximum value out of a matrix.   I have an overlap , maximum transmissible force, NOKOK Matrix   i now need to find the overlap for the maximum transmissible force under the condition "OK"   The values in the matrix are only valid for "OK"   For the given example the correct overlap is 0,127 mm with 649,736 kN   Can anyone help me out how to determine this problem?   I have Mathcad 15   Thank you Br Stefan
