Hi there, need help, i have calculated values of L and R using rnorm function for 1000 intervals with the mean values and the standard deviation values of L and R. The results are in brackets so i assume it is a matrix. Now need to check when L>R and count, i was using if function but needs a scalar result and L and R are not, any ideas?

I am having trouble creating a template for use in Mathcad 15.  Specifically, I cannot get my text specification to "stick".   I go into the templates directory in Mathcad, choose the Griffin template in which I have specified my desired parameters, including 11 pt arial text.   Now, I save the template, open Mathcad click on new, open the Griffin template.  Everything works except the text.  It comes out at 12 point arial.   What am I doing wrong ?

A direct quote from the current tweet about the Digital Engineering editorial:"PTC Mathcad Prime engineering math software has 30-something years of continuous development and field use that has honed its features."Really?I seem to recall a step change between Mathcad 15 and Prime 1.0 a few years ago.

Hello all,Tonight I am attempting the below problem:The given correct answer is given as 14.49m for the centre of gravity from the keel of the platform i.e. KG=14.49mI have so far approached this as follows:I.e. the transverse Gravity to the Metacentre is equal to the Keel to the centre of Buoyancy + Centre of Buoyancy to the transverse Metacentre - KG.I.e. KG=KB+BMT-GMTI have also worked on the assumption that:i.e. BMT is equal to the transverse second moment of the water plane divided by the underwater volume. I've also assumed that the KB is half the draft.Further I have assumed that as the cylindrical columns are at the waterplane, the second moment of these areas will be about a circle and can be calculated as:i.e. Pi * diameter to the power of 4/64.I have carried on as below.I think that I have calculated the underwater volume correctly and the second moment for one column correctly. I am not sure how to equate the total second moment for the total waterplane i.e. all 8 columns.

i am  having difficulty with the integration problem.i dont even know mathcad can solve it or not.@Thanks in advance

I'm trying to use Mathcad to solve a series of equations. I keep getting the error message "This variable is undefined" Any tips?

Dear All,Could you please help me to solve or answer whether it is to possible to:1. make a different width for each part of the header, pls see picture2. Make a grid lines for the work sheet like in Mathcad Prime.Thank you in advance for all your comments.Kind regards,Jan

  Dear PTC Community,  I am trying to solve one dimensional heat conduction in a hollow cylinder (for example a pipe) with heat convection both from the inside and outside.  Is there a way to use parametrized solve block with pdesolve? I want to be able to use the solve block for different values of Ti and hi, in a for-loop.  I appreciate your advice.  Thanks in advance  🙂 

Hello,I have attached my worksheet.Is there a way for mathcad to tell me if an infinite series converges or diverges? And if it converges, what it converges to? Thank you!!

I have some data that I am reading into a worksheet.  For each line of data, I would like to solve for 3 unknowns.  I have three equations so that should work.  I have checked the equations within the solve block by copying them outside the solve block to see if they work and they do as can be seen after the find statement.I tried 'trace error' and it seems to give a nonsensical error.  Something about a squared term should be a function.I also tried to make my vectors of length 1 and 'trace error' gives a different error.I thought of trying to make the solve block a function but I am not sure how to get it to return 3 different values which don't have consistent units.The worksheet and example data is attached.  I am using v14.0 M020.I appreciate your suggestions.Jake

Hello everyone, I am going to parametrize solving block (odesolve func) and then define corresponding coefficients by least square.  But unfortunately, I meet problem after parametrization of the solve block. Could someone help me with this? Thank you in advance. You can find example of the program attached

Hi everybody,I am new in coding with the Mathcad. I am trying to code a model related to civil engineering (geotechnical engineering), but I have faced several problems. I think the problem is not that much hard, but I couldn't solve it. I wonder If somebody could take a look at it and give me some hints about that. I have attached my file as well as the picture of what I am trying to code.Thanks in advance.

Hi,I have a dropdown list in Mathcad. I have sections in it and it calls in some of the required section properties under it.Unfortunately whenever I close and reopen the file, the list jumps back to the very first item and forgets what I had chosen before.I have tried to protect the area but didn't help.Could anyone tell me how can I fix it to remember my choice?Thanks in advance,Viktoria

In Mathcad 15 page breaks are shown and it is possible to repaginate the document.  That feature appears to be missing in MCD Prime 4.0.  Am I missing something?In Mathcad 15 it is possible to align equations along the left document margin.  That appears to be missing in MCD Prime 4.0. 

Hello,I am using Prime 3.0. I want to export data from a trace in a plot into Excel. How can I do this?I can see one can import data from Excel, but what about exporting from Mathcad to Excel?Thanks in advancePascal

Hi Every oneCan any body Help me about this problem?I Have Attached main file which is done by MathCad Prime 4.0This is distributed load on a simple support beam and "V" and "M" are shear and moment, regardless of what is physical meaning of this parameters just as a mathematicsI do not know why M(x) does not return any answer while I can take answer in MathCAD 15  with same formulas!!I do not want to use Evaluate for first integral because it makes another problem when "a=0"Thanks in AdvanceRamakjavascript:;

Hi all,I have some problem in computing ODE in AdamsBDF.I want to use AdamsBDF function as below,S = AdamsBDF(initial, 0, 10^6, 10^10, D)But, when I try to use 'S' as above, I am getting an error as not enough memory for this operation.Is there any other way to increase the sampling interval.I attached my code below.

Hi, I had to change computers and my Mathcad 15 only loads 75%. I am trying to load onto a 64bit machine with Mathcad 15 M010.  Is that the problem?  Prime 3 loaded fine and is working but I need 15 to convert my old files.

How do I break up an expression so that it appears to be two lines?

HI, I just need some help to simplify Hz in a simple mathematical  program.

Hello, I am new to Mathcad and am getting the error "unable to form derivative matrix" when using OdeSolve. I think I may not be able to use OdeSolve inline like I am doing, so I tried putting it outside of the solve block as well. Can anyone confirm this? And what should I do instead? I appreciate your help. I am re-posting this because I have changed the code since then thanks to help, but am still getting the same issue. The file is attached, and the screenshots are displayed below.

I am having difficulty with opening the attached file with my version of mathcad could some please open the attached file and print contents as pdf? Thanks
