NAME
mkgeo_ball -- build an unstructured mesh of an ellipsoid, in 2d or 3d
SYNOPSIS
mkgeo_ball options [n]
EXAMPLE
The following command build a triangle based 2d unstructured mesh of the unit ball mkgeo_ball -t 10 > ball-10.geo geo -mayavi ball-10.geo or in one comand line: mkgeo_ball -t 10 | geo -mayavi -
DESCRIPTION
This command is usefull when testing programs on simple geometries. Invocation is similar to mkgeo_grid (see mkgeo_grid(1), mkgeo_ugrid(1)). It calls gmsh as unstructured mesh generator. It avoid the preparation of an input file for a mesh generator. The optional n argument is an integer that specifies the subdivision in each direction. By default n=10. The mesh files goes on standard out- put.
ELEMENT TYPE OPTIONS
-t 2d mesh using triangles. -q 2d mesh using quadrangles. -tq 2d mesh using both triangles and quadrangles.
THE MESH ORDER
-order int The polynomial pproximation mesh order, for the curved boundary, as defined by gmsh. Defualt is order=1.
THE GEOMETRY
The geometry can be ellipse/ellipsoid inscribted in the [a,b]x[c,d] rectangle or the [a,b]x[c,d]x[f,g] parallelotope. By default a=c=f=-1 and b=d=g=1, thus, the unit balls are considered. -s Only a surface mesh is generated: a curved line in 2d or a curved surface mesh in 3d. In 3d, supports both '-t' and '-q' options. -a float -b float -c float -d float -f float -g float
BOUNDARY DOMAINS
The meshes defines a domain named boundary that groups all boundary sides.
OTHERS OPTIONS
-fix -nofix By default, internal face and volume node from gmsh are recomputed, since they have incorrect coordinate that destroy the conver- gence properties of isoparametric high order elements (order >= 3). The -nofix option skip this correction: this option is avail- able for test purpose. -clean clear temporary files (this is the default). -noclean does not clear temporary files. -verbose -noverbose print intermediate commands and information messages.
