Unstructured + Boundary Layer Meher Code

Posted January 10, 2015 at 19:08 by truffaldino

Zip archive contains

bc.f95 - auxiliary program which takes x y airfoil coordinate file and produces contour (bc) files for furteruse by meher dist_mesh_new.f95

bl.f95 - auxiliary program which takes x y airfoil file and produces sub mesh (boundary layer) file for further use by mesher dist_mesh_new.f95

dist_mesh_new.f95 - mesher


IMPORTANT !!!!!! : Read "ReadMe.txt" before using the code

Make appropriate changes Pathes/filenames...

Example 3 for dist_mesh_new.f95

Posted December 31, 2014 at 17:16 by truffaldino

1) use bl.f95 and e184.txt (or .dat) as input for bl.f95 to generate boundary-layer submesh file e184_bl.txt (or .dat) for further use by dist_mesh_new.f95

2) run Example 2 of dist_mesh_new.f95 (look the code) using input files:

mum_m=1
m_file(1)="e184_bl.txt"
num_c=2
c_file(1)="wt_bc.txt"
c_file(2)="wake_bc.txt"

2D unstructured mesher in F90

Posted August 9, 2012 at 08:23 by truffaldino

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
