Good afternoon.Can you please tell me if there is software for converting the calculations made in Mathcad to a C-like code?Or maybe there are libraries under Mathcad for this purpose?The task is to transfer the "model" described in Mathcad to the code in any of the higher-level programming languages.
Hello eveyone, I am trying to calculate erosion on clay levee's where the soil protection has failed. To do this I need to calculate 2 variables. The way the variables are calculated differs depending on one of the variables that I need to calculate... Hope this makes sense. To illustrate I added a picture with a program where the different ways of calculating and the statements for each phase are given. I am trying to calculate the variable cotat and hklif. So in the case cotat < 8 it would be the equition from the first if statement. Other variables like Hs dk hb etc are known cause they are input in the sheet.
Dear all, Sorry for this simple question , I am just a new user in this software. I would be grateful if someone can help me to know how to derive the trigonometric equations without getting a solution as in the attached thread. In other words, instead of driving the trigonometric equations as per attached, the software does this for me. Thanks in advance
Hi all, I have the need to use a MathCAD function (possibly) but I am not sure how to achieve what I would like the program to try to do. My situation is essentially I havea fixed-fixed beam of circular cross section with a known span L anda uniformly distributed load w. So using standard beam equations I have the max moment is M = wL^2/12 so the max stress is S = [(wL^2/12)(OD/2)]/I where I = (pi/64)(OD^4-ID^4), OD is known and the max deflection is y = wL^4/384EI where E is a known constant. What I would like to eventually find is the thickness t = 0.5*(OD-ID) which just satisfies y = 0.1 and S = 2000. Usually by hand, I would work use S = 2000, find the value of I and work out ID, then find t, substitute into the formula for y and see if equal to 0.1. I can probably assess it graphically but that would probably not give me too exact of an answer. However I am not sure what functions would help me get MathCAD to automate this for me. Can anyone shed any light on
Hello, Mathcad is giving me error messages that units used are not compatible although I've declared the variables I'm using. What do I do wrong? Thanks, maurits
For example i have deployed some random nodes in (200x200), but the problem is i want to form some random cluster's, like the given graph, please look my mathcad file !
This may have been resolved previously but I cannot find the answer so if anyone can help, I'd appreciate it. I have 5 pages of equations that use variables stated at the very top. I want to have a table at the end stating that if a single variable changes at the beginning, this is how the final equations calculate out. Is there a way to do this? Thanks in advance.
Estimados todo Buen día Mi consulta es como puedo realizar operaciones dentro de una tabla para que cuando los datos de una columna dependan de otra pueda calcularlos automáticamente. Gracias
Hi to all, I am further experimenting with my Naval Architecture calculations in MC. In the attached MCP3 file, can anyone tell me why the integral returns what seems to be an infinite number of answers when the answer I expect to get is 50m^2? Thanks, Andy.
For example: i have attached the picture about it (check once) ! i searched for documentation but i didn't find any!
Estimados todos Buen día Mi consulta es la siguiente como puedo multiplicar dos vectores ya definidos pero elemento a elemento, es decir: V=[2 4 6 8] W= [3 6 9 12] Z=V*W=[6 24 54 96] Cual es el operador (*) a utilizar. Muchas gracias
Hello everyone, I need your help converting or perhaps coding a new routine to plot a 3D truss. Yesterday after the help of some of you guys, I was able to get my hands on a solution for a similar problem here in this forum but solution was done in PRIME. I tried the whole day yesterday to convert the code to the old V15 mathcad without success. So now I am asking y'all for help once again. Thanks!
I'm trying to solve the attached equation for T. W, U, V, Theta and Phi are all defined values. I can't seem to get solve,T to work. It just says undefined. I can partially do it by breaking it down but I get to the final step and cant seem to get Mathcad to rearrange in terms of T. Anyone got any advice?
hi, how can I isolate V? It give me a answer in matrix but I want it in m/s.
I want to be able to able to make sure that my vector numbers are always equal to or greater than this number (Wall.Aspect.Ratio.Min) but i am getting an error sign because my L.1 is a vector and not scalar. Any way I can go around that?
How do you convert xmcd files to mcdx without Mathcad 15? Or just view the xmcd files would be nice. I do not have Mathcad 15 anymore, how do we do this? Mathcad prime 4.0 canot convert them without Mathcad 15 please help
I am posting this question again. I created several Mathcad files (using 15) last year. I tried to open them yesterday. I got a message saying "not a valid XML file" . Then I tried to attach the offending file and it would not attach, saying "file contents do no match file type". Can someone out there explain what is going on and how to correct this. Has PTC developed a fix for the problem? My email address is dmgjr@suddenlink.net
I have several files I created last year. They are typed as xml files. Now when I try to open them I get a message that they are not valid xml files. Can someone explain why this happens and how to fix it. I am attaching one of the offending files. When I try to attach the file I am told the contents do not match the file type
Hey! I'm having an issue with my mathcad file. It says the file isn't supported tho i remember saving it yesterday and it worked perfectly. I'll attach the file below. I'm on the schools computer so i cant access program data and its saturday so I'd be happy if someone could help me ASAP! Thanks in advance!!!
Hi I have a problem, i don't find why ? (equations for intersection point of 3 planes) Probably syntax error ??? in first solve block, i have copy / paste equastion of symbolic evaluation for plane equation
Hi all. I have some files that read data from text files and then does some calculations. In some instances that data may be moved which basically "kills" the calculations. How can I "embed" the data into the Mathcad file so that it becomes self contained? Do i have to copy the data into a matrix or table or is there another way? Thanks.
Do you know how a catenary lies on the cone? Without friction!
Hi, I have a rather large matrix (1100 x 40) from which I tried to filter out the data that have NaN content, but to no avail. When I searched for the problem in my code I found that the the filterNaN function sometimes didn't filter NaNs although the entite columns was filled with NaN. I tested this by checking whether the value is indeed NaN, which it is. Checking whether the same value is a scalar returned also a positive?!? (see attache sheet which contains a subset of that data). Does anybody have an explanation for this contradiction and/or can tell me how to avoid this? Thanks Raiko
How to find upper and lower envelop of the signal ? please check my mathcad file !
