@sand15 Thank you for your help this is a nice start. First I will give you some additional explanation on what is the background of the data. The data coming from calcified human aortic valve leaflets. We are trying to developed techniques to repair these sick leaflets and are comparing the same leaflet before and after treatment. In my previous software I first smoothed the data in order to find the minimum and maximum values which prevented the errors you had in the first plot. However, the second plot seems to be OK.

Additional questions and comments:

Is it possible to extract also the extension value at the maximum and minimum values?

Each cycle goes from 0.1 N to 5 N. In my previous attempts I took the slope between 2 and 4 N but I would love if it is possible to use polynomial functions to define them as you did. But how easy is it to compare statistical two polynomials?

I also would like to have the surface area of each of the tree cycles if possible.

I know I am asking a lot, but although I find maple a fantastic software, my transition from my previous software is sometimes pretty hard, as in this project.

Thank a million for your help

@sand15 Thank you so much for your willingness to look at my problem. I have attached the separate files below:

@acer thank you for your swift response; it worked, and your help is highly appreciated!

@dharr thank you for your swift response, it worked and your help is highly appreciated!

@nm Thank you for your help, I tried it but it did not solve the issue, so I went back to 2025.1

@nm thank you for your help. I tried to follow your instructions and this is what I get

Did I do something wrong or is there another issue?

@ecterrab Thank you for your prompt reply but I do not understand because my worksheet indicates the physics is installed see attached document PhysicsPackagePresent.mw

@ecterrab I followed your advice given to nm11633 but I get the following shown in the attached pdf as I am not sure the document file will give you the problem dsolve_gives_parsing_error_maple_2025_2_nov_20_2025.pdf. Can you help me with it?

Thank you in advance

@WD0HHU I also use Maple 2025. I show you a larger print screen below. I hope this helps

@Carl Love thank you for your prompt reply. I believe there is a misunderstanding. If you go to the top of the mapleprimes webpage there is a  tab Products

If you click on it you will find questions and answers for the different versions of Maplesoft products. Before there was also a section for Maple Flow, which is now no longer present. So you could ask specific Maple Flow questions such as differences in syntax between Maple and Maple Flow. 

@alex_b Thank you for your answer. I first downloaded the Maple Flow 2025 trial version and then saw that I could also download the Migration Assistant. I checked all required boxes but nevertheless could only download a trial version without Migration Assistant. I hope you can give additional assistance in short notice on how to do this as the Migration Assistant is a very nice feature for an old mathcader as myself and my trial version has only 11 days left.

Thank you for your help.

@Samir Khan 

Would it be possible to send also a link for the migration assistant to me?

Thank you in advance!

@manasp 

I have the same problem, and mentioned it at the sales force yesterday. 

@acer Thank you for your swift reply, highly appreciated!

@Scot Gould thank you for the update. I upgraded my Office in the meantime from 32 bit to 64 bit and do not see problems as long as I make the file in the 64 bit version. In that case the first row becomes automatically the header in the dataframe.
