Mesh 2d of a complex geometry with FORTRAN

Click For Summary

Discussion Overview

The discussion revolves around creating a structured triangular mesh in 2D for a complex geometry using FORTRAN. Participants seek clarification on the requirements and specifications for the task, as well as references or resources that could assist in the implementation.

Discussion Character

  • Exploratory
  • Technical explanation
  • Homework-related

Main Points Raised

  • One participant expresses the need to create a structured triangular mesh in 2D for a complex geometry using FORTRAN.
  • Another participant requests more details about the task, including the type of input information and expected output.
  • A suggestion is made to formulate a clear specification for the program, including tasks, input, and output.
  • References to existing programs and resources are mentioned, indicating that similar tasks may have been addressed previously.
  • A participant notes the importance of understanding whether the task is for learning purposes or for practical completion.
  • The original poster clarifies that they are working with the control volume finite element method and need the mesh for a specific complex geometry, specifying that they have found resources for ordinary geometries but not for complex ones.
  • The expected output is stated as the coordinates of the nodal points of the mesh.

Areas of Agreement / Disagreement

Participants do not appear to have reached a consensus on the specifics of the task or the resources available, indicating that multiple views and uncertainties remain regarding the requirements and existing references.

Contextual Notes

The discussion highlights a lack of clarity in the original request, with participants noting the need for more detailed specifications regarding the geometry and the intended use of the mesh.

You're going to have to explain a lot more about what you want to do.

ok, I have to do a mesh 2d for a specific geometry with Fortran, have you any reference or cite can help me to do that

It's still not clear what your task is.

Are you trying to write a Fortran program to generate a 2-D mesh? What sort of starting information would you be working with? What sort of output are you looking for, in addition to the coordinates of the nodal points of the mesh?

As a general rule, when writing a computer program, regardless of the language used, it is always a good idea to

1. Formulate a clear and detailed specification for what tasks the program is intended to accomplish
2. List the input information which the user will be expected to furnish
3. Describe the output results expected.
 
I presume this has been done before, for example, take a look at this page listing many kinds of program; entry 693, for example, sounds like the kind of thing you are looking for, then entries starting at item 769 regarding triangulation...

The above references may be too much for you...you request is so vague it tends to reveal quite a bit of inexperience.

Are you supposed to implement this program for the purpose of learning? Or are you supposed to just get it done for whatever purpose?
 
thank you for your answers, I work with the method control volume finite element method and I need to do with fortran the mesh 2d to specific geometry, (I found the mesh for on ordinary geometry, but not a complex geometry)
so the output that I need is the coordinates of the nodal points of the mesh
