class always_use_face_centroid_with_periodics(service, version, mode, path)

Bases: TUIMethod

When enabled, ANSYS Fluent uses quad face centroids when creating subtets in cases with periodic boundaries.

class boundary_layer_tracking(service, version, mode, path)

Bases: TUIMethod

Enables/disables the calculation of the particle time step that considers both the cell aspect ratio and the particle trajectory. This method improves the accuracy of the predictions in boundary layer cells, particularly in layers where flow gradients are large.

class check_subtet_validity(service, version, mode, path)

Bases: TUIMethod

When enabled, checks the validity of a subtet when the particle first enters it. If the subtet is found to be degenerate, the tracking algorithm modifies to accommodate it.

class enable_automatic_intersection_tolerance(service, version, mode, path)

Bases: TUIMethod

Enables/disables the automatic calculation of intersection tolerance. By default, the tolerance used in intersection calculations is scaled by the residence time of the particle in the cell to improve robustness. For most cases, the scaled tolerance is sufficient to identify all intersections of the particle trajectory and the subtet faces. You can set the intersection tolerance manually using the set-subtet-intersection-tolerance text command.

class enable_barycentric_intersections(service, version, mode, path)

Bases: TUIMethod

Enables/disables an alternative method of calculating intersections with cell boundaries. Barycentric intersections are linear calculations and are faster than the default intersection algorithm. The default intersection algorithm is second-order for stationary meshes; therefore, using the barycentric intersection may sacrifice accuracy. You must verify that the barycentric intersections provide comparable results to the default intersection method. This option is available only for 3D stationary meshes and the double precision solver.

class enable_high_resolution_tracking(service, version, mode, path)

Bases: TUIMethod

Enables/disables high resolution tracking.

class enhanced_wallfilm_location_method(service, version, mode, path)

Bases: TUIMethod

Enable enhanced method of locating film particles on faces.

class load_legacy_particles(service, version, mode, path)

Bases: TUIMethod

Load particles that were tracked without high-resolution tracking enabled.

class project_wall_film_particles_to_film(service, version, mode, path)

Bases: TUIMethod

Enables/disables projecting existing particles to Lagrangian wall film to track using high-resolution tracking. When reading in a data file that contains wall film particles previously tracked with the existing ANSYS Fluent tracking method, you need to either clear the particles from the domain or project their positions to the wall film surface using the project-wall-film-particles-to-film? text command prior to using the high-resolution tracking method. After tracking the particles for one timestep, this option can be disabled to improve performance.

class remove_stuck_particles(service, version, mode, path)

Bases: TUIMethod

.

class set_film_spreading_parameter(service, version, mode, path)

Bases: TUIMethod

Set the spreading parameter for Lagrangian wallfilm particles.

class set_subtet_intersection_tolerance(service, version, mode, path)

Bases: TUIMethod

Specifies the tolerance used in intersection calculations. This tolerance will be scaled by the characteristic cell crossing time of the particle if the enable-automatic-intersection-tolerance? text command is enabled. If that option is disabled, the specified tolerance will be used without scaling. The default intersection tolerance is 10-5.

class sliding_interface_crossover_fraction(service, version, mode, path)

Bases: TUIMethod

Specifies the fraction of the distance to the subtet center to move the particle. At non-conformal interfaces, the nodes used for the barycentric interpolation are different on either side of the interface. This may result in incomplete particles due to discontinuities in the variable interpolation. The number of incomplete particles may be reduced by moving the particles slightly off of the sliding interface. Recommended values range between 0 and 0.5.

class use_barycentric_sampling(service, version, mode, path)

Bases: TUIMethod

When enabled, this option provides improved accuracy and parallel consistency when sampling particles at planes. This item is available only with the 3D solver. Using the double-precision solver and bounded planes is recommended.

class use_legacy_particle_location_method(service, version, mode, path)

Bases: TUIMethod

Enable legacy method of locating particles in cells.

class use_particle_timestep_for_intersection_tolerance(service, version, mode, path)

Bases: TUIMethod

Enables/disables the use of the particle timestep for the subtet intersection tolerance with axisymmetric grids (default: enabled). If disabled, the tolerance will be calculated in the same manner as non-axisymmetric meshes (a scaled value of the tolerance which is set using the define/models/dpm/numerics/high-resolution-tracking/set-subtet-intersection-tolerance text command).

class use_quad_face_centroid(service, version, mode, path)

Bases: TUIMethod

Enables/disables using quad face centroids when creating subtets. This option changes the way hexahedral cells are decomposed to avoid creating degenerate subtets.

class use_velocity_based_error_control(service, version, mode, path)

Bases: TUIMethod

Enables/disables an alternative method of timestep adaption. By default, ANSYS Fluent uses the half-step method of timestep adaption with particle integration. This alternative method of controlling the integration timestep based upon velocity changes is faster; however, you need to ensure that the accuracy is comparable for your specific application.

class wallfilm_relocation_tolerance(service, version, mode, path)

Bases: TUIMethod

Set the relocation tolerance for wallfilm particles after remeshing.
