2D unstructured mesher in F90

Posted August 9, 2012 at 08:23 by truffaldino

Tags 2d mesher, fortran, unstructured

This is 2D unstructured mesher.

tri_mesh.f90 is a mesher and the rest are input files

Example 1: Cavity flow driven by upper cavity wall

file: cavity_bc.txt

Example 2: flow past NACA 0012 airfoil

files: NACA0012_bc.txt - airfoil
wt_bc.txt - wind tunnel
wake_bc.txt -wake

Description of the program is placed in the header of tri_mesh.f90

Methods for creating cellZones and faceZones

Posted July 26, 2012 at 11:03 by kalyangoparaju

Friends,

I've been playing around a lot with the creation of cellZones and faceZones and here is what I have to report !

Till now I have found 3 ways to do it. ( I am sure there are more)

1. To use setSet utility and cellZonesSet and faceZoneSet commands.
This works amazingly well and creates the zones. A small problem can arrise if you are trying to set zones for an internal flow case and at the center of your geometry you have level 0 cells....

Mentally tortured after two nights thinking on the applications of Computational Fluid Dynamics, Computation, Programming and my contribution to the field.
