calfem.mesh.create_mesh¶

Purpose:

Create a mesh for the given geometry using GMSH. This function serves as a convenient wrapper around the GmshMeshGenerator class to generate finite element meshes from geometric definitions.

Syntax:

cfm.create_mesh(geometry, el_type=2, el_size_factor=1, dofs_per_node=1, gmsh_exec_path=None, clcurv=False, min_size=None, max_size=None, meshing_algorithm=None, additional_options='')

Description:

Source docstring:

Create a mesh for the given geometry using GMSH.
This function serves as a convenient wrapper around the GmshMeshGenerator class
to generate finite element meshes from geometric definitions.
Parameters
----------
geometry : object
    The geometry object defining the domain to be meshed.
el_type : int, optional
    Element type identifier. Default is 2.
el_size_factor : float, optional
    Factor controlling the element size. Default is 1.
dofs_per_node : int, optional
    Number of degrees of freedom per node. Default is 1.
gmsh_exec_path : str, optional
    Path to the GMSH executable. If None, uses system default. Default is None.
clcurv : bool, optional
    Enable/disable curved element generation. Default is False.
min_size : float, optional
    Minimum element size constraint. Default is None.
max_size : float, optional
    Maximum element size constraint. Default is None.
meshing_algorithm : int, optional
    GMSH meshing algorithm identifier. Default is None.
additional_options : str, optional
    Additional GMSH options as a string. Default is ''.
Returns
-------
mesh : object
    The generated mesh object containing nodes, elements, and connectivity information.
Examples
--------
>>> mesh = create_mesh(geometry, el_type=3, el_size_factor=0.5)
>>> mesh = create_mesh(geometry, min_size=0.1, max_size=1.0)
