Mathcad

I have MathCad 14.0 and would like to plot a 3-D polyhedral surface from a set of (x,y,z) vertices. I could not find any plotting option/function to this - am I missing something? Does MathCad 15 have this functionality?

As far as I know, vertically-stacked fractions are always displayed in Mathcad equations. Is there a way to display fractions in "x/y" format? This would be helpful for powers with fractions, e.g., x^(y/z) in large equations with lots of powers.

Hello everyone.As I can get all the values that belong to a particular component based on a data table as shown in the attached sheetThanks in advance

Hello,I am currently looking at combined heat transfer (radiation - convection - conduction). When radiation is considered, the differential equation becomes non-linear, and thus I figured using MathCad would be great for solving the DEQ as a function of parameters. As a note, the text I am using/refering to is: Thermal Radiation Heat Transfer 5th Ed. by Howell & Siegel, Chapter 7. This chapter is mainly dealing with numerical solutions and setting up the equations, but I would like to know how to solve them using MathCad.Attached is a worksheet and a few pictures of the example problems I am trying to solve, in which there is a graph showing the solutions. I am hoping I can get Mathcad to solve the equations as a function of parameters.

I came across an article discussing research in building programming languages to speed up development of simulation programs. Here is the link. And here are some quotes from the article:"They have created a language similar to the language of mathematics.""... in the field of programming there is a classic problem linked to selection of the correct units used to describe physical quantities""Our new programming language is easy to use, it takes less time to write programmes, and the sources of error have been removed."Reinventing the wheel comes to my mind.

Hi,The Mathcad document have some calculations from the old article. The article says that all the calculations are done on a computer. However, my results do not coincide with those shown in the article. On the screenshots you can find input information (a, t), the formula for calculating the value (x, y, b_0, b_1). I have tried to carry out calculations with different accuracy, but the result is still different. Maybe I missed something?

Hello to everyone,I'm just giving a try to the MP3.0 trial version.Basically, somewhere in the worksheet I need to find the max. value of a function over the range of its parameters.Unfortunately I have some problems with the programming tools.I'm struggling for a while to implement correctly the program I want as I'm not familiar with this programming feature of MathCAD, but I think there is a problem with units and/or external functions to the program.I made a file with an example.What do you think ?

I do not see the add-on in my Resources list so I am not certain if it installed correctly.

Hello,please scroll down in my attached sheet. i have placed a red arrow near the questions. There are a total of two questions. Thank you !

Hello,Attached is a short sheet with a Minimize function. I'm getting a "variable undefined" error.Can anyone help?TIA

Hello everyoneI need to find the value of a variable (Dev) per iteration, assigning an initial value, but I get error and truth do not know why.Hope you can help

Hi.I'm trying to output a vector based on a vector made by range variables. I'm not sure how to start this so any help is appreciated.My input vector 5x1 and I want one output vector to give me a 3x1 one vector based on values in my vector which is bigger than value a and one output vector which is smaller than a. See attached for more info.I can kind of solve it but I want the output vectors to be 3x1 and 2x1 vectors with no zeroes.Thanks in advance!

I would like to use interactive 2d drawing in mathcad where variables can be passed to active dimensions in the drawing and redraw it to scale with dimensions displayed. Years ago this was possible using smartsketch which was actually supplied free with mathcad.Is there a similar solution for prime 3.0 that doesn't invovle buying Creo?

Hello,please scroll down in my attached sheet to the bottom two curves. i am not sure why it is showing more curves than what i am trying to plot. Thank you!

I tried the converter on some of the handbooks that installed with the v15 download. A result sample is attached.I'm assuming that there is supposed to be a plot on the traces. Could somebudy offer an opinion as to why there isn't?ThanksJoe

I'm using MathCAD Prime 3.0 and when I try to use the following equation, the units show incorrectly. MathCAD is displaying the units correctly, as f'c has units as MPa and MathCAD is showing (MPa)^(1/2), but this is incorrect for that equation. The equation is emprical and should have a result in MPa. How can I remove the units (and just insert some text in their place), or specify units for this equation. Thank you!

Hi,Is it possible *somehow* in Mathcad to have more-than-2 dimension matrix ? I don't want to represent them (that would be really awkard), just to define and read the elements, do some math ... the usual. The only thing I saw that came close was to use nested matrix, but that gets a bit messy in terms of reading. X[a,b,c looks a lot better than ((X[a)[b)[c ...Thanks

This is a Mathcad 15 example of a function returning multiple values with different units.

I opened the worksheet (that was created in Mathcad 11) in Mathcad 15 M030 version. The document is rather large and I can not edit the contents of the file and select anything in therein. What is wrong with this file?

Hi,I have a dll I have used extensively over the years and it works in Win XP with Mcad14, but for some reason now I am on Win7-64b the functions in my dll are no longer accessable in mathcad.How do I get user dll's to work in Mathcad14 in Win7/64b?I have attached the dll in question.Thanks.

Can someone explain me why i can't get the value in right unit? The final unit should be obtained in kPa, instead i get sth far different

I have been working on this for sometime now. I have a for loop that I want to calculate and make diagrams of. My problem is that how can I get all of the steps in the for loop?See file attached. I have been trying to find help from here and from other sources, but I still can't find a way to print/plot the steps. I have heard that I should have used a other software to do this simulation but I wanted to work with this software. THX in advance for the help. Lauri

Hello folks,I ran into this problem of the match function. When used in a loop it claims to not have found a match. When used on its own it works just fine; see attached worksheet.Does anybody know why? I'm using MC15 on a Win 7 machine.Thanks in advanceRaiko

Hey there,I have received a file from my colleague which was made in MC 15, I would really appreciate if someone could convert it into mcdx (Prime 2) file since I can not handle it (do not have MC 15 010) and once in the past I used my trial so I can not get a licensed MC 15.Take careMik

Not sure if this is even possible with Mathcad but thought I'd ask the question.I have several collapsible areas on a mathcad file. Depending on a answer from a formula at the start of the mathcad file some of the calculations would be irrelevant and are therefore hidden in collapsible areas.i.e. if the answer is >10 then all fomulas are applicable If not then 3 areas are not required and these are generally hidden.Is there a way of autohiding collapsible areas based on a given answer from a formula?
