Mathcad

Dear MathCAD Prime experts,Currently I have had a problem of opening my work file. I was doing my engineering design of Footing in MathCAD Prime7.0, but I was not get done on work I saved and closed. When I opened the for continuing my work the error message was popped up " The file type is not supported. Log file is located at C:\ProgramData\PTC\Mathcad Prime\Logs\MathcadPrime_Exception20210505_145107.log'' and I could not even open my file, I tried. Have somebody experienced this kind of problem? I would like you somebody else kindly spare your time to have a look at my attached file for making it to be as normal as it can be?I am here for looking forward for your help. Thank you!

Hello,   I'm trying to solve a double integral but I wait for hours and the result didn't appear. Could anyone tell me if Mathcad solve this type of equation?   Thank you    

Hi,   I'm trying to replicate a template that evaluates the shear and moment of a simple beam. The problem is that to W array, I've got the message that n is invalid. The index should be an integer that it is n=3, no less than origin that it is because i have set up origin=1 and no greater than the last element which i don't know if is true. Any idea how can I fix it?   Thanks Thank you all for taking the time. It was the origin :1 that was not written as it should so no all sorted. Thank you very much anyway!!  

I am trying to calculate the following equation for a project that i have. Nor the find function or the root function doesn't give me the result. I am currently using the Mathcad Prime vers 7.0. What can i do? Thank you!

Hello! How to use Mathcad15 functions in C ++ builder? I need to enter formulas and output 3Dgraphs in my application.

Hello , Is it possible to get all the values back to Excel as a product.of L*B as an area. I tried with one row but it is too much time consuming. I believe there is some other way to do may be by programming but I am not sure how to do that can please someone help.   Somehow I was unable to add excel sheet so attaching screenshot  Don

Hi everybody,   I am using Mathcad prime 6.0. I have tried to make some calculus of temperature, but it seems that Mathcad has a problem with calculation of temperature. First I tried: 1F+1F=461.67F (it is not 2F!!!), then 2F/1F=1 (it is not 2).    I don't really know if that is a technical bugs of Mathcad Prime? or it is just a bad copy of Prime in my laptop, or Did I miss something?    

Animation is not just a toy. This is also a good illustration of what numerical precision is.This is an illustration for my article, which is being prepared for publication. Is it possible to solve this problem (two weights moving along a chain) absolutely precisely - without jerking. The Mathcad 15 sheet in attach.  

What does this mean? I could not find it in the list of error messages. The attached program was working until I set a_1, b_1 and d_1 = 0.

Hello, currently I am using Mathcad prime 7.0 trial version, While I'm doing definite integration the upper limit is outlined by red color and there shows an error notice that the value must be real for upper limit value. so what I will please solve my problem. also give response as soon as possible.

I'm trying to convert an old MCD file to the XMCD format -- but the converter fails with the message "Could not start mathcad conversion process"   How can I convert this file so that I can use it with 'PTC Mathcad prime' ?

Hi,   Given the recent posts on the forum, I was curious to try and drive a mass, spring, damper system using a square wave. Luc posted an interesting solution for creating a square wave. There are decent quick sheets for mass, spring, damper systems in Mathcad 15. So I just combined the two things. I did have to modify the square wave definition some. The state space solver is faster and more robust. However, using odesolve provides a check. Working with each solver is different. The examples help show how to work with each solver.   The examples allow you to see what happens when you use a square wave instead of a cosine wave. Also, what happens when the square wave duty cycle changes. You can see that traditional ode solutions don't match reality. I've seen this before as well. The classic text book solutions are limited in a number of ways.   Also, thanks to the other forum members who helped me create these examples. I couldn't have did it without their help.  

is there a way to convert the odesolve output to a matrix, so that the max and min can be found. apparently the odesolve output is a function. i attached a worksheet. i want to convert t and x to matrices.

I need to linearly interpolate from a table, which I attached with some examples.I appreciate any help... Thanks a lot!

I have solved the Problem of Malfatti circles  with Prime 6 or Mathcad 15 - see pls attach Can you solve it more sort, more nice 😉    

"You are a three-dimensional being, and your shadow is two - dimensional. This means that you are most likely the shadow of a four-dimensional being!"Is it a new type of diagramm - not a triangle, but a Tetrahedron diagram How can we plot it in Mathcad? See please the Mathcad 15 sheet in attach! The edges of a tetrahedron are a function of one argument with a maximum, the sides of a tetrahedron are a function of two arguments with a maximum, and the interior of a tetrahedron is a function of three arguments with a maximum" Etc Tetraeder diagram

I am encountering a problem wherein the resolution of the plotted points in the chart component is too low. I made a manual range of 0 to 0.1 to see the sine wave more clearly. I tried looking at all the settings in the chart component but nothing seems to work.   

Hello,   Hello everyone,   I have a very simple question. I solved an integration and I was unable to generate a table with the data of that integration. I send my file here. Can anyone help me?   Thank you

Trying to solve a systems of 3 equations with 3 unknowns by means of SOLVE BLOCK and MINERR function. (or find). It doesn't provide any error message but it seems not to calculate any root; it simply provides the three guessed values as the results without running any iteration.

Hello, I am trying to solve a series of two first order ODEs, the ODEs are a function of time but also include a piecewise temperature component that varies with time. I believed at first this is what was breaking the solver but when I make the temperature constant the solver remains broken. Can anyone see where my mistake is? I am thinking it is most likely the constants and/or initial conditions.    Thanks for any help that can be provided. 

Hi i make a new calculus for free fall with linear friction i can see the theory , but i have difficult to talking to Prime 😅 and chart! i have this:   But i can't make a chart !!! unit problem I think in the same way the evaluation of the limit does not give the expected result    

Hello, Can someone help me with this? I want to translate some Matlab code into Mathcad 15.   Thanks.

hi,   i've never used symbolics before and i'm having a bit of trouble. i attached the worksheet in question. i'm trying to solve for v1 and v2. however, u1 and u2 are also coming out of the Find function. i think i'm missing something.   thanks,   anthony

I'm doing a simple calculation as shown in the picture attached. E has units of psi F has units of in A = (EF^3)/12 A should have units of lb*in, but Mathcad gives it the unit of (lb*ft^2)/(s^2)   Why is this happening?
