MeshQuality¶ The class provides functions to quantify mesh quality
Compute the radius ratio for all cells. @param mesh (std::shared_ptr<const Mesh>) @return MeshFunction<double>
The cell radius ratio radius ratio geometric_dimension * * inradius / circumradius (geometric_dimension is normalization factor). It has range zero to one. Zero indicates a degenerate element.
-
static std::pair<double, double>
radius_ratio_min_max(const Mesh &mesh)¶ Compute the minimum and maximum radius ratio of cells (across all processes) @param mesh (const Mesh&) @return std::pair<double, double>
The [minimum, maximum] cell radii ratio (geometric_dimension * * inradius / circumradius, geometric_dimension is normalization factor). It has range zero to one. Zero indicates a degenerate element.
-
static std::pair<std::vector<double>, std::vector<double>>
radius_ratio_histogram_data(const Mesh &mesh, std::size_t num_bins = 50)¶ Create (ratio, number of cells) data for creating a histogram of cell quality @param mesh (const Mesh&) @param num_bins (std::size_t) @return std::pair<std::vector<double>, std::vector<double>>
-
static std::string
radius_ratio_matplotlib_histogram(const Mesh &mesh, std::size_t num_intervals = 50)¶ Create Matplotlib string to plot cell quality histogram @param mesh (const Mesh&) @param num_intervals (std::size_t) @return std::string

static void
dihedral_angles(const Cell &cell, std::vector<double> &dh_angle)¶ Get internal dihedral angles of a tetrahedral cell
-
static std::pair<double, double>
dihedral_angles_min_max(const Mesh &mesh)¶ Get internal minimum and maximum dihedral angles of a 3D mesh
