intersection_control#

class ansys.cfx.core.generated.pre_processing.settings_261.intersection_control_1.intersection_control(name: str | None = None, parent=None)#

Holds advanced parameters to control the details of interface discretization.

Attributes

Attribute	Summary
enabled	Enable the INTERSECTION CONTROL object.
option	The ‘Intersection Control’ option.
permit_no_intersection	When true, the solver will run when there is no overlap between the two sides of a GGI/MFR interface. Use this parameter for transient rotor-stator cases with rotating valves etc. that sometimes are fully closed to the geometry.
discernible_fraction	Control surface discernible area fraction.
edge_scale_factor	Degenerate surface length scale tolerance.
periodic_axial_radial_tolerance	GGI periodic surfaces cannot be constant axial surfaces or constant radial surfaces. This parameter controls the tolerance used to determine if the surface is in one of these two invalid situations.
circumferential_normalized_coordinates_option	Sets the calculation recipe for eta.
face_search_tolerance_factor	Scaling factor applied to element sized based separation distance that is used to find candidates for the GGI intersection.
face_intersection_depth_factor	Scaling factor applied to element sized based separation distance that is used to intersect the sides of a GGI interface.
angle_tolerance	Angle tolerance for intersection (in degrees) used for the direct intersector. The normal vectors of two intersected faces has to be in opposite direction with respect to the specified tolerance.
bitmap_resolution	Bitmap resolution to use on a mesh face when calculating the mesh intersection for a nonmatched domain interface.

Included in:

Parent	Summary
mesh_connection	Defines how the meshes on a domain interface are connected.
solver_control	Holds all objects that control discretization and execution of the solution process.
