Discussion Overview
The discussion revolves around solving a perturbation problem using Mathematica, specifically related to fluid mechanics. Participants seek clarification on the problem's parameters and the context of the equations provided.
Discussion Character
- Homework-related
- Technical explanation
- Debate/contested
Main Points Raised
- One participant presents a differential equation and boundary conditions, seeking assistance with Mathematica.
- Another participant questions whether the inquiry is homework and requests more details about the problem.
- A participant clarifies that they are a master's student in mechanical engineering working on their thesis related to fluid mechanics.
- Several participants emphasize the need for more context regarding the variables involved, such as ε, u0, and u1, to provide meaningful help.
- One participant mentions having solved the momentum equation using the perturbation method and seeks guidance on encoding and validating the solution in Mathematica.
- There are repeated requests for clarification on the parameters and functions involved in the problem.
- Some participants express willingness to assist but indicate that they require more explicit information about the problem statement.
Areas of Agreement / Disagreement
Participants generally agree that more information is needed to understand the problem fully. There is no consensus on the specifics of the problem or the solution approach, as multiple viewpoints and requests for clarification are present.
Contextual Notes
Limitations include unclear definitions of variables and parameters, as well as the absence of a complete problem statement, which may hinder effective assistance.

Is this homework? In any case, you will probably have to give more details.

Can you give even more details? While I may not be the one to be able to help you here, I think that not knowing what ε, u0, u1, etc. represent is going to make it hard for anyone to give you advice.

I solved the momentum equation of the fluid by perturbation method. I need to encode and validate the solution with mathematica. I used direct expansion in the solution of the perturbation. I want information about the code.

Which parameters do you know, what is a function of what, what are uo and u1?
You can’t expect help if you don’t explain the problem sufficiently for others to understand it.

I'm still missing the context, but it is nice if you have the solution now.

So, you solved the problem by hand, but you have to do it in MMA, for your thesis? Is that correct? I know a little MMA, and I'm willing to look into it, but I can't read the photos of your solution, so I'm going to need some more information. Reading your original post, it looks like you are working with 4 functions - u, u0, u1 and epsilon. Is that right? It seems a little peculiar to me. A more explicit problem statement would be helpful.
