Method Details

[hide private]

init(self, dim=3, element_size=1.0, order=1, keep_files=False)
(Constructor)

Initializes the gmsh design.

Parameters:

dim - spatial dimension
element_size - global element size
order - element order
keep_files - flag to keep work files

Overrides: object.__init__

getMeshHandler(self)

Returns a handle to a mesh meshing the design. In the current implementation a mesh file name in gmsh format is returned.

Overrides: design.Design.getMeshHandler

getScriptHandler(self)

Returns a handler to the script file to generate the geometry. In the current implementation a script file name is returned.

setOptions(self, algorithm=None, optimize_quality=True, smoothing=1, curvature_based_element_size=False, algorithm2D=None, algorithm3D=None, generate_hexahedra=False)

Sets options for the mesh generator.

Parameters:

algorithm2D (in self.DELAUNAY, self.MESHADAPT, self.FRONTAL) - selects 2D meshing algorithm
algorithm3D (in self.DELAUNAY, self.FRONTAL) - selects 3D meshing algorithm
curvature_based_element_size (`bool`) - switch for curvature based element size adaption
smoothing (non-negative `int`) - number of smoothing steps
optimize_quality (`bool`) - switch for mesh quality optimization
generate_hexahedra (`bool`) - switch for using quadrangles/hexahedra elements everywhere.

Overrides: design.Design.setOptions

setScriptFileName(self, name=None)

Sets the filename for the gmsh input script. If no name is given a name with extension I{geo} is generated.
