Hello all,i am using MATHCAD 15,i want to customise the temperature Default unit (K-Kelvin) in SI to cutomised unit (Degree celcius - oC)i have tried to convert this usingTools / worksheeet options / Unit system / Temperature(K) / change unit /in the unit column there is celcius option is givenonly "CHANGE DELTA C" is available in need degree celciusI am new to math cad plaese help me RegardsBalaji.K

Hi everyone,I would like to know if there is a way in MathCAD to solve such an equation: Where (unfortunately ) Sa(w,x) is known and G(w) is unknown. All other parameters can be considered known. The equation comes from a book about Eartquake Engineeering, and gives a possible relationship between Response Spectrum and Power Spectrum, together with Fourier Spectrum (less common) they are the type of spectra commonly used in earthquake engineering. So the unknown function G (in my problem the power spectrum) would appear at the same time under integral and outside of it. Schematically it would be something like: with F(w) known (but not a simple analytical function, it would have to be a splined interpolation, see small example on the left in the first picture above) and X(w) unknown.If, as I believe, there is no MathCAD way, I would be grateful for some hints to known numerical methods to solve the problem... my calculus lessons are a little dated Thanks a lot in advanceClaudio

Hi,I have tried to solve equations of current ramping up and down in a power converter, including the series (parasitic) resistances in the circuit. Solve block works fine and finds sensible results, except ... one of the 2 parameters I am searching (aa) is a duty cycle, and therefore, should be unitless, and it comes out of the solve block with a unit (Amps, like the other variable). I just can't find what I've got wrong, since all the equations I input will only work if the variable is unitless, so why on earth would the solve block add a unit that doesn't work ? Unless I missed something ...Thanks

I have entered into http://support.ptc.com/support/mathcad_downloads.htm, from my support page. I see there are many links to download versions of the application. For example, I found:Product: MathcadVersion: 14.0Datecode:M020License: Single-UserFile(s) to download:Is this the complete software (version 14.0) or is it only an update? is the single-user license included, or how can I obtain one of mathcad 14?In advancce, thank you very much.

Good Afternoon Community,If anybody can tell me why I'm not getting an output to the attached file. My goal is to calculate the lateral stiffness of a pile group called alpha_sub_uF, but when I substitute the pile spacing S_p and xi in the procedure, I did not get any output. I have cut and paste the equation I'm trying to program at the bottom of the worksheet. Please help.Regards,Boyer

How could I download an offline instalation file of Mathcad Express?That's because I don't have right now a broadband internet conection at home, only a minimal conection that will let me only activate the product, but not to download it. I need download the offline version, so I could install it in my personal computer.In advance, thank you very much.

The solve block in Prime 3.0 contains section in which to enter equations, parameters, etc. That's OK, but I'm trying to put solve blocks into a document (a book manuscript) and I need to be compact. As it is, it takes half a page to display all this stuff and tryinig to compress it makes it unreadable. In MCAD 15, solve blocks could be very compact while still being easy to read.Is there some way around this problem?

Hi all, I was wondering if there is way to change the default page size from letter to A4 in Prime 2 / 3 without using templates? Is there a config file somewhere?Any advice appreciated.

Hey guys,Do you know what could be wrong when installation is stuck at 75%? It is a brand new laptop (lenovo T540p)I have installed all needed components (C++,.Net framework, MSXML and so) but the installation stops at 75% and nothing happens.I have mathcad 15, win7 pro.

Hi everybody,I am trying to make an iterative calculation in Mathcad 15, but I seem to fail. I am trying to calculate rock stability in water by calculating the shear stresses caused by currents and waves. The bed roughness (kr) is a function of the D50 that I am calculating. see the photo. Can anybody tell me what I am doing wrong? If you need more info just ask. Thanks in advance.Kind regards

Hi All,I make frequent use of steam table calling functions in my Excel spreadsheets, and I would like to use this capability within Mathcad Prime 3.0. However, so far I have been unable to figure out how to bring a sheet with it's steam table calls into an Excel component in Mathcad Prime 3.0.I think the functions are inside of a couple of .bas files, and I have tried to save those in the Excel component, but this seems to cause trouble with Mathcad.I will attach a small sample Excel file showing how the calls work.If anyone can advise how to make this work I would very much appreciate it.Thanks,--Eric SeelyeP.S. The steam calls in this sheet are the work of Magnus Holmgren (formerly of www.x-eng.com) However, he seems to have dropped out of site. I was unable to find him when I last tried some months ago. Anybody know what happened to him?

Hello!I can't find an option for reversing axsis (from minus to plus) in diagramms. Like a mirror image respect to x-axis. Is it even possible? Thank you!Sami

In MathCAD 14, I am having trouble making a 3D scatter plot when the matrix-function contains an element that is a natural log function. The same matrix-function plots OK If I substitute and different function for the natural log function. I have included an example file; why does the p.2xyz function plot OK and p.1xyz not plot at all?

Hello Everybody. I need help with proving the above, in general case for p. Thank you in advance. Best Regards.

Hello Everybody, Now I need help with transferring a term to RHS. ( Illegal operand ). How to correct them ? Thank you in advance for your time and help. Best Regars.

Hello Everybody,Could you please help me with this problem. In the attached worksheet, there is function sp(k,b), where k is the variable and "b" is the parameters. for different set of parameters, there is a phase shift between sp(k,c1) and sp(k,c2).How can I find the amount of the phase shift? or minimize the phase difference? The ultimate goal is to find a new set of parameters as close as possible to the model parameters "c1"Thank you very much in advance

In the attached Prime 3.0 worksheet I am attempting to graph a function of functions. This is something that I did readily in Mathcad 15. Is this possible in Prime 3.0? Is there a change I need to make to this function to make it graphable?

Im having problems using the solve functionSometimes it works fine, other times it does not. I cannot figuree out what the problem is, but a workaround is sometimes to strip my equations for units. But I rather keep the units.The problem is that I dont get a result, but MathCad says"This variable is undefined. Check that the label is set correctly". Im not quite sure what it is MathCad is trying to tell me.Does anyone have a idea of what the problem is and how to work around it?

So, I'm completely new to Mathcad and am literally using it for my first time ever for a grad assignment. I am having difficulties with a couple of things in particular.First, and most importantly, I am getting an error which states "This value must be a function." Having defined the term and function in question previously, I am just not sure where I'm going wrong. I'm sure it's something easy about how I'm typing it in or what I forgot to do, but I need someone more experienced to help me out.Secondly, in the "error 2" worksheet attached, I am getting an error about incompatible units. If anyone could help me with one or both of these errors, I'd greatly appreciate it. Sorry for my lack of knowledge of the program.

I find myself trying to solve a set of equations, which are a function of two variables (P2 and D), with different units (psi and pulg), whose values I intend to find out.How I can deal with this problem?Thank in advance

I am a recent convert from MathCad 15 to Prime 3.0. In the attached Prime 3.0 worksheet, what is the correct formatting for stating if a variable is not an answer (NaN) to set a variable to one value, and if it is an answer to set it to another variable?

HiI'm trying to compute soil pressure resultants from soil pressure and depth vector.The problem is that the resultant vector should have fewer rows than are in the depth and in the pressure vectors.The solutions should be made in a way that it works for n-layers.Thank you for help in advance.

Dera friendsI am going to simulate a Gaussian electromagnetic wave propagation in a multi layer media (pulse shaping, transmission and refelctivity). On the following web address I have found a some how similar package but the link directs me to ptc.com.http://www.mpassociates.gr/software/distrib/science/mathsoft/application_files.htmlDo you know how to get a similar code to get a primary idea?Thank youPayman

Is there a way to raise each element of a matrix to a power without having to do it manually each one?
