high_res_tracking

class ansys.fluent.core.generated.solver.settings_271.high_res_tracking(name=None, parent=None)

Bases: Group

Advanced settings for high-resolution particle tracking. High-resolution tracking subdivides polyhedral cells into tetrahedra (“subtets”), tracks particles through subtets, and interpolates flow variables continuously to the particle position. This improves robustness and accuracy and is recommended for most cases.

Attributes

Attribute	Summary
enabled	Enables high-resolution tracking (recommended for improved robustness and accuracy).
always_use_face_centroid_with_periodics	Uses face centroids when creating subtetrahedra in cases with periodic boundaries.
flow_interpolation	Selects the interpolation method for flow variables at the particle location. Interpolation ensures particles
boundary_layer_tracking_enabled	Adjusts particle time step in high-aspect-ratio boundary layer cells. Reduces particle step size in ~%high aspect-ratio boundary layer cells to prevent skipping thin cells and improve wall interaction accuracy.
subtet_validity_checking_enabled	Checks for invalid subtetrahedra caused by warped cells. Detects invalid or inverted subtetrahedra in ~%highly skewed meshes, preventing tracking errors or particle loss.
auto_intersect_tol_enabled	Automatically scales intersection tolerances for robustness.
barycentric_intersection_enabled	Uses barycentric coordinates for intersection calculations.
particle_relocation	Settings controlling particle location and relocation.
stuck_particle_removal_enabled	Removes particles that become stuck at edges or faces.
barycentric_sampling_enabled	Uses barycentric coordinates when sampling particles on surfaces.
quad_face_centroid_enabled	Uses quad face centroids when constructing subtetrahedra.
