ConcentricCircleMeshGenerator
This ConcentricCircleMeshGenerator source code is to generate concentric circle meshes.
Overview
The ConcentricCircleMeshGenerator object is used to generate a 2D mesh for concentric circles. Users can refine the mesh by providing a high number of rings for each specified concentric circle region or a high number of sectors in each quadrant. The test, concentric_circle_mesh_generator.i, explains the use of the ConcentricCircleMeshGenerator object. To execute the test, only generating a 2D mesh:
~/projects/moose/test/moose_test-opt -i concentric_circle_mesh_generator.i --mesh-only
To execute the test with the engineering and mathematical physics solvers:
~/projects/moose/test/moose_test-opt -i concentric_circle_mesh2.i
commentnote
Be aware: ConcentricCircleMeshGenerator only works with Replicated meshes.
More Information
ConcentricCircleMeshGenerator works by creating the first quadrant, called "top_right." An input parameter, called "portion", controls which portion of mesh would be generated. Any other one-fourth portions of circles are generated by rotating the "top_right" portion. Half portions are generated by stitching two different one-fourth portions depending on users' preference.
Users must provide the input parameters, such as:
number of azimuthal sectors in a quadrant
list of radii: specific locations of radii of concentric circles
list of rings: numbers of rings for concentric circles
inner mesh fraction: ratio of the length of the inner square to the radius of the innermost circle mesh
whether the volume for concentric circles should be preserved or not (true/false)
iteration number: number of iterations for Laplace smoothing
Users can choose if the mesh for the enclosing square is added to the concentric circle mesh or not. A portion can be specified, however, it is not required. The default setting generates the full concentric circles.
Developer Information
If one needs to enhance ConcentricCircleMeshGenerator, Laplace smoothing has to be constrained to the center circle. Efficient algorithms for adding nodes and elements, including the connectivity, may be needed. They can be found in ConcentricCircleMeshGenerator.C.
