NAME¶
mkgeo_obstacle - mesh of the obstacle-in-channel (rheolef-7.2)
SYNOPSIS¶
mkgeo_obstacle [options] [nx [ny]]
EXAMPLE¶
The following command build a triangle-based 2d unstructured mesh of the [-L,L]x[0,c] with a unit circle hole at origin.
mkgeo_obstacle > obstacle.geo
geo obstacle.geo
DESCRIPTION¶
This command is convenient for building a mesh for the obstacle-in-channel geometry, as it is a very classical benchmark in complex fluid flow problems. It calls bamg unstructured mesh generator with anisotropy feature. The mesh files goes on name.geo where name is the basename for the output (see option -name below). The three auxiliary files required for automatic mesh generation with Rheolef combined with bamg are also provided:
name.bamg
name.bamgcad
name.dmn
THE GEOMETRY¶
-c float
-L float
-cartesian
-zr
-quarter
-half
-N int
of the circular obstacle is considered. Default is N=100.
THE DISCRETIZATION¶
-hmin float
BOUNDARY DOMAINS¶
The boundary sides are represented by domains: obstacle, axis, wall, upstream and downstream.
OTHERS OPTIONS¶
-name string
-[no]split
-[no]clean
-[no]verbose
