To import data into the working document, you can also use "READEXCEL("file", "range", [emptyfill])" the built-in function, which returns a matrix from a defined range in an Excel worksheet.

In the attached worksheet there is a plot error (Plotting failed. Replace complex values and NaN by real numbers.) I've tried using failterNaN to remove the NaNs. Is there a way to remove the complex results?

I can't open your sheet, only see the jpg's.

In Filter 1 you define ORIGIN:=0 (that's default any way.)

In Filter 2 you have

so the first element of xv is not defined, 0 by default, but no units.

I don't see where you define x, but:

suggests that x has no units--you put in feet and Mathcad divided by meters to balance the units.

I think that's your basic problem.

filterNaN does not work the way you use it and would not help anyway.

A 2D plot will only fail with that error if ALL values are NaN or invalid and I suspect that the latter is the case.

I can't read P3.1 and I could not be bothered to switch between three JPGs to debug.

But I would suggest you try to evaluate your function V for a simple single value.

What happens if you type V(2 ft)= ? Where does the error trace to?

EDIT: Fred could possible be right (again). Try to define a range variable for x, like x:=1ft, 1ft+1in .. 10 ft or whatever seems appropriate.

Dear PTC experts, i would like to ask your invaluable pertinent to the attached file. In this problem, i am evaluating Zpq for a frequency (f:=2.45*10^9), the value of Zpq turns out to be complex and i have seperated the real and imaginary parts. I would further like to evaluate Zpq for a frequency range i.e., from 2.2*10^9-2.6*10^9 with step size of 0.5*10^9. Moreover, i would like to plot Zpq against the mentioned frequency range. Any help in this regard would be highly appreciated. Many thanks

If so, then use WRITEEXCEL(M, "file", "range") - writes a matrix M to an Excel file.

The latest version of .NET Framework is 4.6/4.6.1 (link: .NET Framework 4.6 - Search Microsoft.com). You installed this version?

Fred,

Please find PDF document of this worksheet in attachment.

We will wait for feedback from you.

Dear Luc Meekes,

Thank you very much for the kind help. It solved my problem, with your detailed guidance, I was able to duplicate it perfectly.

Good day shabby sam

I am glad you were able to find a solution!

Would you please mark Luc's answer correct as it make the information easier for others to find.

Thank you!

Toby

Thank you all very much, the issue was that x was not defined.

Thanks! It's interesting to see the entire sheet..

Yes I have installed this one.

I need help from this community.

Could you describe the initial problem in more detail?

For a basic oscillator, you are correct:

The frequency and displacement of a vibration are independent. For a given frequency a larger displacement means a larger acceleration.

If that doesn't answer your question, then please post a more detailed question.

Hi all,

This is my first post on the forums and I wanted to ask a general question on gaining proficiency in Mathcad.

In a nutshell, I am an experienced Project Engineer by profession (mainly mechanical & structural bias) but in order to widen my skill set, I have recently been training part-time in Finite Element Analysis, which I enjoyed immensely. To complement this, I asked my colleagues which packages would best complement my new skills in FEA and ANSYS software and Mathcad was one which came highly recommended.

With all of this in mind, I wanted to ask if any of you can offer advice and hopefully point me in the right direction (ie. training courses, PDFs available online) so that I can work on Mathcad from the ground up. I am completely self-financed and so I am looking to do this on a tight budget, but I am motivated and can devote more than enough time to making this happen. Thanks in advance for any input.

Best regards,

- Chris

In case of linear vibration 'Time period' or 'Frequency' will be same for different displacement ?
