mkgeo_sector1rheolef

Usage

Examples

The following command build 2d unstructured mesh of the triangular region delimited by the three points (0,0), (1,0), (1,1):

    mkgeo_sector
    geo sector.geo

Overview

This command is convenient for building a mesh for a sector of a square pipe section, as it is a very classical benchmark in complex fluid flow problems. It calls bamg unstructured mesh generator. 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

The geometry is the triangular sector (0,0), (a,0), (a,b). By default a=b=1.

-a float
-b float

The discretization

The optional n argument is an integer that specifies the subdivision in each direction. By default n=10.

Boundary domains

The boundary sides are represented by domains: axis, boundary, and bisector.

Options

-name string

Set the basename for the output files. By default, the basename is sector.

-[no]clean

-[no]verbose
