PROGRAM:

NAME


mkgeo_ugrid -- build an unstructured mesh of a parallelotope, in 1d, 2d or 3d

SYNOPSIS


mkgeo_ugrid options [n]

EXAMPLE


The following command build a triangle based 2d unstructured mesh of the unit square:

mkgeo_ugrid -t 10 > square-10.geo
geo -mayavi square-10.geo

or in one comand line:

mkgeo_ugrid -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)). 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 output.

The command supports all the possible element types: edges, triangles, rectangles,
tetraedra, prisms and hexahedra. It supports also mixed 2D with triangles and quadrangles:

mkgeo_ugrid -tq 10 | geo -mayavi -

and mixed 3D with tetraedra, prisms and/or hjexaedra:

mkgeo_ugrid -TP 10 | geo -mayavi -
mkgeo_ugrid -PH 10 | geo -mayavi -
mkgeo_ugrid -TPH 10 | geo -mayavi -

ELEMENT TYPE OPTIONS


-e 1d mesh using edges.

-t 2d mesh using triangles.

-q 2d mesh using quadrangles.

-tq 2d mesh using both triangles and quadrangles.

-T 3d mesh using tetraedra.

-P 3d mesh using prisms.

-H 3d mesh using hexahedra.

-TP

-PH

-TPH 3d mesh using a mixt between tetraedra, prisms and/or hexahedra.

THE GEOMETRY


The geometry can be any [a,b] segment, [a,b]x[c,d] rectangle or [a,b]x[c,d]x[f,g]
parallelotope. By default a=c=f=0 and b=d=g=1, thus, the unit boxes are considered. For
instance, the following command meshes the [-2,2]x[-1.5, 1.5] rectangle:

mkgeo_ugrid -t 10 -a -2 -b 2 -c -1.5 -d 1.5 | geo -

-a float

-b float

-c float

-d float

-f float

-g float

BOUNDARY DOMAINS


-sides

-nosides
The boundary sides are representd by domains: left, right, top, bottom,front and
back.

-boundary

-noboundary
This option defines a domain named boundary that groups all sides. By default,
both sides and the whole boundary are defined as domains:

mkgeo_ugrid -t 10 > square.geo
geo square.geo
mkgeo_ugrid -t 10 -nosides > square.geo
geo square.geo
mkgeo_ugrid -t 10 -noboundary > square.geo
geo square.geo
mkgeo_ugrid -t 10 -noboundary -nosides > square.geo
geo square.geo

REGIONS


-region

-noregion
The whole domain is splitted into two subdomains: east and west, This option is
used for testing computations with subdomains (e.g. transmission problem; see the
user manual).

mkgeo_ugrid -t 10 -region | geo -

CORNERS


-corner

-nocorner
The corners (four in 2D and eight in 3D) are defined as OD-domains. This could be
usefull for some special boundary conditions.

mkgeo_ugrid -t 10 -corner | geo -
mkgeo_ugrid -T 5 -corner | geo -

THE MESH ORDER


-order int
The polynomial approximation mesh order, as defined by gmsh. This option enable a
possible curved boundary, when applying a suitable nonlinear transformation to the
mesh. Defualt is order=1.

OTHERS OPTIONS


-clean clear temporary files (this is the default).

-noclean
does not clear temporary files.
