source
HOHQMesh.generate_mesh — Method
generate_mesh(control_file;
              output_directory="out",
              mesh_filename=nothing, plot_filename=nothing, stats_filename=nothing,
              verbose=false, subdivision_maximum=8)

Generate a mesh based on the control_file with the HOHQMesh mesh generator and store resulting files in output_directory.

You can set the mesh filename, the plot filename, and the statistics filename using the keyword arguments mesh_filename, plot_filename, and stats_filename, respectively. If set to nothing, the filenames for the mesh file, plot file, and statistics file are generated automatically from the control file name. For example, path/to/ControlFile.control will result in output files ControlFile.mesh, ControlFile.tec, and ControlFile.txt.

You can activate verbose output from HOHQMesh that prints additional messages and debugging mesh information with the keyword argument verbose.

To override the maximum number of allowable subdivisions in the quad tree during meshing adjust the value of subdivision_maximum. The default value of subdivision_maximum is 8, meaning that elements can be up to a factor of 2^8 smaller than the background grid. Note, think before doing this! It could be adjusting the boundary curves, background grid size, adding local refinement regions, or some combination may remove the need to adjust the subdivision depth.

This function returns the output to stdout of the HOHQMesh binary when generating the mesh.

source
HOHQMesh.generate_mesh — Method
generate_mesh(proj::Project; verbose=false, subdivision_maximum=8)

Generate a mesh from the information stored in a Project created using the interactive mesh functionality. First a check is made if a background grid exists and all inner/outer boundary curves are valid.

This function will then make a HOHQMesh control file from the control dictionary proj.controlDict and use it to call the wrapper function that interfaces with HOHQMesh. The resulting mesh and control files will be saved to proj.projectDirectory. Also, if there is an active plot of the mesh project it will update to display the generated mesh.

With the optional argument verbose one can activate verbose output from HOHQMesh that prints additional messages and debugging mesh information.

To override the maximum number of allowable subdivisions in the quad tree during meshing adjust the value of subdivision_maximum. The default value of subdivision_maximum is 8, meaning that elements can be up to a factor of 2^8 smaller than the background grid. Note, think before doing this! It could be adjusting the boundary curves, background grid size, adding local refinement regions, or some combination may remove the need to adjust the subdivision depth.

This function returns the output to stdout of the HOHQMesh binary when generating the mesh.
