mkgeo_ugrid
mkgeo_ugrid(1rheolef) rheolef-6.1 mkgeo_ugrid(1rheolef)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 inte-
ger 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 suit-
able 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.
